Family report of Wolf-Hirschhorn syndrome in twins / 中华神经科杂志

Objective:To explore the clinical manifestations and genetic characteristics of Wolf-Hirschhorn syndrome (WHS) to improve the ability of diagnosis and differential diagnosis of the disease.Methods:The clinical features and auxiliary examinations and treatment of a proband with WHS caused by microdeletion of 4p16.3 segment who admitted to the Third Affiliated Hospital of Zhengzhou University in December 2021 were recorded, and whole exome sequencing (WES) of the family was performed. The prognosis was followed up.Results:The female proband, 11 months old, presented with convulsions at the age of 8 months, with the characteristics of heat sensitivity and cluster seizures, and her identical twin sister had a similar medical history. Physical examination found malnutrition, retarded development, special face, prominent forehead, wide nasal bridge, small jaw, precordial murmur and grade 3/6 murmur in the whole period, hyperactivity of P2, and low limb muscle tone. The whole exon and copy number variation (CNV) test of the family revealed that the proband had a 1.99 Mb heterozygous deletion in the chromosome 4p16.3 segment, including WHSC1 (NSD2), WHSC2 (NEFLA) and other genes. Copy number variation sequencing (CNV-Seq) of the proband and her sister showed 1.97 and 1.92 Mb heterozygous deletion of chromosome 4p16.3, respectively. Genealogical analysis by quantitative polymerase chain reaction revealed that the CNV was de novo, and it was determined to be a pathogenic variant according to the American College of Medical Genetics and Genomics guidelines. The proband took sodium valproate orally, and her sister took oral sodium valproate, zonisamide, and levetiracetam successively, and at the same time they received family rehabilitation training. The age at the last follow-up was 1 year and 8 months. Neither of them had convulsions again in the past 3 months, but the developmental delay was obvious. Conclusion:WHS patients may present with growth retardation, epilepsy, Greek warrior helmet-like special face, and congenital heart disease, and may have microdeletions in the chromosome 4p16.3 segment.

A Case of Wolf-Hirschhorn Syndrome with Early Rehabilitation Intervention from the Neonatal Period / The Japanese Journal of Rehabilitation Medicine

Wolf-Hirschhorn syndrome is a chromosomal aberration caused by a deletion of the distal short arm of chromosome 4, characterized by distinct craniofacial features, failure to thrive, psychomotor developmental retardation, epilepsy, and feeding disorders. We report a case of patient with Wolf-Hirschhorn syndrome who underwent interventional rehabilitation commencing from the neonatal period in the neonatal intensive care unit. The patient was born at gestational age of 38 weeks 0 days, weighing 1583 g, with an Apgar score of 4/9, and was diagnosed with partial monosomy of the short arm of chromosome 4. Postnatal inspiratory stridor exacerbation was noted for which high-flow nasal cannula therapy was initiated. Rehabilitation commenced on the 18th day after the infant's birth, to promote sensorimotor development. Initially, the trunk was in a low muscle tension and unstable state. Therefore, we first prescribed rest followed by sensorimotor rehabilitation. When the infant's clinical condition stabilized, we performed prone and anti-gravity hugging exercises to improve the low trunk tension. Breastfeeding evaluation began 56 days after birth, when the respiratory condition improved. We practiced feeding the infant orally, in collaboration with doctors and nurses, to reduce bending and stabilize the posture when raising the mandible. The infant was gradually able to feed orally and gained weight. Thereafter, he was discharged 141 days after birth. This report concluded that rehabilitation intervention from the neonatal period, in collaboration with the multidisciplinary team and patient's family, contributed to initiation of oral feeding, improvement of sensorimotor development, and smooth transition to home care.

Síndrome de Wolf-Hirschhorn: Descripción de cinco casos caracterizados por microarrays de polimorfismos de nucleótido único / Wolf-Hirschhorn syndrome: Description of five cases characterized by means of single nucleotide polymorphism microarrays

El síndrome de Wolf-Hirschhorn es una entidad polimalformativa debida a la microdeleción en la región distal del brazo corto del cromosoma 4 (4p16.3), el cual produce una serie de manifestaciones clínicas, que pueden variar dependiendo del tipo y tamaño del defecto genético en este síndrome de genes contiguos. Se presentan cinco pacientes, tres de ellos de sexo femenino, todos con los hallazgos clínicos primordiales, con rasgo facial característico de "apariencia en casco de guerrero griego", retraso en el crecimiento y del desarrollo psicomotor. Además de la deleción parcial en la región distal del brazo corto del cromosoma 4, en dos pacientes, se encontraron alteraciones genéticas adicionales, mediante el uso de microarrays de polimorfismos de nucleótido único. Se resaltan las características clínicas del síndrome de Wolf-Hirschhorn con la finalidad de orientar el diagnóstico, brindar una atención médica interdisciplinaria y, a través de su confirmación, brindar un adecuado asesoramiento genético familiar.

Wolf-Hirschhorn syndrome is a polymalformative entity due to the microdeletion in the distal region of the short arm of chromosome 4 (4p16.3), which produces a series of clinical manifestations that can vary depending on the type and size of the genetic defect in this contiguous gene syndrome. Five patients are presented, three of them female, all with the primary clinical findings, characterized by "Greek warrior helmet appearance" facial feature, growth retardation and psychomotor development delay. In addition to the partial deletion in the distal region of the short arm of chromosome 4, two additional genetic alterations were found in two patients, through the use of single nucleotide polymorphism arrays. The clinical characteristics of Wolf-Hirschhorn syndrome are highlighted in order to guide the diagnosis, provide interdisciplinary medical care and, through its confirmation, provide adequate family genetic counseling.

Prenatal diagnosis of Wolf-Hirschhorn syndrome: a case report / 中华围产医学杂志

This study reported a case of fetal developmental retardation indicated by ultrasound from 17+2 to 34+5 gestations.Single nucleotide polymorphism (SNP) array was performed to detect the copy number variation in the whole genome for the fetus and parents.A 2.42 Mb deletion at 4p16.3 was found in the fetus,but in neither parents,which suggesting a de novo mutation.Thus,the fetus was finally diagnosed with Wolf-Hirschhorn syndrome.No obvious'Greek warrior helmet'appearance or other facial deformity was observed in the delivered fetus.

Crecimiento intrauterino restringido como síntoma guía para el diagnóstico genético prenatal del síndrome de Wolf-Hirschhorn en gestación gemelar bicorial biamniótica / Restricted Intrauterine Growth as a Guiding Symptom for Prenatal Genetic Diagnosis of Wolf-Hirschhorn Syndrome in Bicorial Diamniotic Twin Gestation

El síndrome de Wolf Hirschhorn, también conocido como monosomía del brazo corto del cromosoma 4 (4p) o síndrome 4p-, es una rara enfermedad genética descrita por primera vez en el año 1961 por los doctores Cooper y Hirschhorn. El objetivo del trabajo es presentar un caso clínico sobre el síndrome de Wolf-Hirschhorn, que es un trastorno genético raro y aún bastante desconocido que cursa con múltiples anomalías morfológicas congénitas, así como con un retraso neurológico e intelectual de grado variable. La prevalencia de este síndrome es extremadamente baja, teniendo en cuenta que la cifra puede estar infraestimada, dada las pérdidas gestacionales precoces y la dificultad en el diagnóstico prenatal. Reportamos el caso de una paciente con gestación gemelar bicorial biamniótica tras un ciclo de FIV-ICSI, en el que al segundo gemelo se diagnosticó un Síndrome de Wolf-Hirschhorn, luego del estudio por una discordancia de pesos estimados y crecimiento intrauterino restringido de este segundo feto. El patrón clásico de presentación clínica se caracteriza por el desarrollo de alteraciones craneofaciales importantes, retraso en el crecimiento normal tanto prenatal como posnatal y deficiencia mental e intelectual de grado variable. El diagnóstico prenatal debe ser realizado por expertos. Puede sospecharse por un crecimiento intrauterino restringido, ya que se da en 80-90 por ciento de los fetos con esta patología. Una vez diagnosticado, se recomienda el estudio genético de los padres, dado que hasta 15 por ciento de los progenitores pueden padecer un reordenamiento cromosómico equilibrado en el brazo corto del cromosoma 4(AU)

Wolf Hirschhorn syndrome, also known as monosomy of the short arm of chromosome 4 (4p) or 4p-syndrome, is a rare genetic disorder first described in 1961 by doctors Cooper and Hirschhorn. The prevalence of this syndrome is extremely low, taking into account that the figure may be underestimated given the early gestational losses and the difficulty in prenatal diagnosis. The objective of the study is to present a clinical case of Wolf-Hirschhorn syndrome, presenting with multiple congenital morphological anomalies, as well as a neurological and intellectual retardation of variable degree. We report the case of a patient with a bicorial biamniotic twin gestation after a cycle of IVF-ICSI. The second twin was diagnosed with a Wolf-Hirschhorn syndrome, after performing the corresponding study due to a discordance of estimated weights and restricted intrauterine growth of this second fetus. The development of important craniofacial alterations, delay of normal prenatal and postnatal growth, and mental and intellectual deficiency of variable degree characterize the classic clinical presentation. Experts must make prenatal diagnosis. Wolf-Hirschhorn syndrome can be suspected by a restricted intrauterine growth, as it occurs in 80-90 percent of fetuses with this pathology. Once diagnosed, the genetic study of the parents is recommended, since up to 15 percent of the parents can suffer a balanced chromosomal rearrangement in the short arm of chromosome 4(AU)

Prenatal diagnosis of 4p deletion syndrome: A case series report

The 4p deletion syndrome, also known as Wolf-Hirschhorn syndrome, is a well-known genetic disorder caused by a partial deletion of the short arm of chromosome 4. The great variability in the extent of the 4p deletion and the possible contribution of additional genetic rearrangements leads to a wide spectrum of clinical manifestations. Herein, we present our experience with eight cases of 4p deletion syndrome, ascertained prenatally between 1998 and 2016 at our hospital.

Anesthetic considerations for a pediatric patient with Wolf-Hirschhorn syndrome: a case report

Wolf-Hirschhorn syndrome is a rare hereditary disease that results from a 4p chromosome deletion. Patients with this syndrome are characterized by craniofacial dysgenesis, seizures, growth delay, intellectual disability, and congenital heart disease. Although several cases have been reported, very little information is available on anesthetic management for patients with Wolf-Hirschhorn syndrome. We encountered a case requiring anesthetic management for a 2-year-old girl with Wolf-Hirschhorn syndrome. The selection of an appropriately sized tracheal tube and maintaining intraoperatively stable hemodynamics might be critical problems for anesthetic management. In patients with short stature, the tracheal tube size may differ from what may be predicted based on age. The appropriate size ( internal diameter ) of tracheal tubes for children has been investigated. Congenital heart disease is frequently associated with Wolf-Hirschhorn syndrome. Depending on the degree and type of heart disease, careful monitoring of hemodynamics is important.

Uncommon Oral Cleft in Wolf-Hirschhorn Syndrome

Wolf-Hirschhorn syndrome (WHS) is a syndrome with craniofacial and systemic abnormalities, which is related to 4p deletion. A 3-month old girl with an undiagnosed syndrome was referred for evaluation of the cleft lip and palate. Hypotonia, short stature, cardiac malformation, hypertrophied clitoris, and atypical thumb of both hands was observed. Microcephaly, low-set ear, prominent glabella, downslanting palpebral fissures, a characteristic "Greek warrior helmet" appearance, micrognathia, ears with pits/tags and bilateral incomplete cleft lip apart from incomplete cleft palate were observed as craniofacial findings. With clinical diagnosis of WHS, blood was subjected to karyotyping, which showed a 4p15.2 deletion, consistent with the condition. Here is reported the case of this WHS patient with an uncommon oral cleft extending the phenotypic spectrum of the disorder. The child was referred to a multidisciplinary team to reparative surgery of the cleft lip and palate. The patient is on regular medical follow-up and will be further assisted by dentists, physical therapists, occupational therapists and psychologists. The genotype-phenotype correlation of the affected patient with previous WSH syndrome reports is described.

A síndrome de Wolf-Hirschhorn (WHS) é uma condição genética caracterizada por anomalias craniofaciais e sistêmicas, causada por deleção cromossômica na região 4p. Paciente de 3 meses de idade, gênero feminino, foi encaminhada para avaliação de fissura de lábio e fissura palatina, associada a uma síndrome não diagnosticada. A paciente apresentava-se com hipotonia, baixa estatura, malformação cardíaca, clitóris hipertrofiado e implantação atípica do polegar nas duas mãos. Microcefalia, baixa implantação da orelha, glabela proeminente, inclinação baixa das fissuras palpebrais, aparência característica de capacete de guerreiro grego, micrognatia, fossetas em orelhas, fissura labial bilateral incompleta e fissura palatina incompleta foram observadas como características craniofaciais. Com um diagnóstico clínico de WHS, foi realizado o cariótipo, que mostrou a deleção 4p15.2, consistente com a condição. Esse relato de caso apresenta um caso de WHS, com uma fissura oral incomum, ampliando o espectro fenotípico da doença. A paciente foi encaminhada a tratamento com equipe multidisciplinar para correção cirúrgica da fissura labial e palatina. Encontra-se em acompanhamento médico bem como odontológico, fisioterapêutico e em terapia ocupacional e psicológica. Uma correlação entre genótipo e fenótipo pode ser observada nesse relato da síndrome de WHS.

A Case of Wolf-Hirschhorn Syndrome with Periventricular Nodular Heterotopia Presenting with Status Epilepticus

Wolf-Hirschhorn syndrome is a congenital disorder associated with partial deletion of the short arm of chromosome 4. The majority of patients showed characteristic facial anomalies - so called "Greek-Helmet" appearances - mental retardation, growth retardation, and developmental delay. Here we report the case of a 3-year-old girl who was diagnosed as having Wolf-Hirschhorn syndrome immediately at birth with distinct facial anomalies and an abnormal chromosomal karyotype [46,XX,del(4)(p14)]. The patient later presented with status epilepticus and magnetic resonance imaging showed periventricular nodular heterotopia.

Wolf-Hirschhorn (4p-) Syndrome Presenting with Status Epilepticus

Wolf-Hirschhorn syndrome is a well-recognized malformation syndrome with multiple congenital anomalies, resulting from partial deletion of the short arm of chromosome 4 (4p-). All affected individuals have intrauterine and postnatal growth retardation with marked feeding difficulties, developmental delay, and intellectual disability. Additionally, most of patients have seizures from early infancy. Although seizures are common with this syndrome, presenting with status epilepticus (SE) is rare. We report two cases of Wolf-Hirschhorn syndrome presenting with SE.

Wolf–Hirschhorn syndrome: A case demonstrated by a cytogenetic study.

We present a case with a 4p terminal deletion, evidenced in GTG-banded chromosome study. Phenotypic signs described in the classical Wolf–Hirschhorn syndrome were found on clinical examination of our patient.

Anesthetic experience using total intra-venous anesthesia for a patient with Wolf-Hirschhorn syndrome: A case report / 대한마취과학회지

We present here the case of a 33-month-old male patient with Wolf-Hirschhorn syndrome (WHS) and who underwent tympanoplasty and myringotomy. WHS is caused by a rare chromosomal abnormality, which is the deletion of the short arm of chromosome number 4. The typical craniofacial features of WHS patients such as micrognathia, microcephaly and the muscular weakness can make using neuromuscular blocking agents and performing intubation difficult. Moreover, there are a few previous case reports showing that malignant hyperthermia occurred during and after an operation in which the anesthesia was done with inhalation agents, so special anesthetic care is needed when operating on a WHS patient. By carefully intubating the patient and using total intravenous anesthesia, we performed successful anesthesia without any complications. We describe here the anesthetic management of a WHS patient and we review the relevant literature.

The Wolf-Hirschhorn Syndrome in Fetal Autopsy: A Case Report

Wolf-Hirschhorn syndrome (WHS) is a malformation associated with a hemizygous deletion of the distal short arm of chromosome 4. Herein we report a fetal autopsy case of WHS. A male fetus was therapeutically aborted at 17(+0) weeks gestational age, due to complex anomaly and intrauterine growth retardation, which were found in prenatal ultrasonography. His birth weight was 65 g. Mild craniofacial dysmorphism, club feet, bilateral renal hypoplasia, edematous neck, and left diaphragmatic hernia of Bochdalek were found on gross examination. On GTG-banding, the fetus revealed 46,XY,add(4p) karyotype and the mother revealed 46,XX,t(4;18)(p16;q21.1), with normal karyotype of the father. Array comparative genomic hybridization performed on the autopsied lung tissue revealed loss of 4p16.2-->4pter and gain of 18q21.1-->18qter, suggesting 46,XY,der(4)t(4;18)(p16.2;q21.1)mat of fetal karyotype. This suggested deletion of 4p, compatible with WHS inherited from the mal-segregation of a maternal translocation t(4;18)(p16.2;21.1). Therefore, our fetus was both genotypically and phenotypically compatible with WHS.

Recombinant Chromosome 4 with Partial 4p Deletion and 4q Duplication Inherited from Paternal Pericentric Inversion / 대한진단검사의학회지

Pericentric inversion of chromosome 4 can give rise to 2 alternate recombinant (rec) chromosomesby duplication or deletion of 4p. The deletion of distal 4p manifests as Wolf-Hirschhorn syndrome (WHS). Here, we report the molecular cytogenetic findings and clinical manifestations observed in an infant with 46,XX,rec(4)dup(4q)inv(4)(p16q31.3)pat. The infant was delivered by Cesarean section at the 33rd week of gestation because pleural effusion and polyhydramnios were detected on ultrasonography. At birth, the infant showed no malformation or dysfunction, except for a preauricular skin tag. Array comparative genomic hybridization analysis of neonatal peripheral blood samples showed a gain of 38 Mb on 4q31.3-qter and a loss of 3 Mb on 4p16.3, and these results were consistent with WHS. At the last follow-up at 8 months of age (corrected age, 6 months), the infant had not achieved complete head control.

Síndrome de Wolf-Hirschhorn: reporte de un caso clínico y revisión de la literatura / Wolf-Hirschhorn syndrome: case report and literature review

El síndrome de Wolf-Hirschhorn es un trastorno cromosómico atribuible a una delección parcial del brazo corto del cromosoma 4 (4p-). Está caracterizado por hallazgos craneofaciales típicos en la infancia (“apariencia de guerrero griego” de la nariz, microcefalia, frente alta con glabela prominente, hipertelorismo, cejas muy arqueadas, filtrum corto, boca en carpa, y micrognatia, entre otros), retardo del crecimiento pre y postnatal, hipotonía y retardo del desarrollo. Los pacientes también pueden tener epilepsia y anormalidades que involucran otros órganos. El diagnóstico puede ser realizado por análisis citogenético convencional, el cual detecta la mayoría de los casos.

It is characterized by typical craneofacial features in infancy (“Greek warrior appearance” of the nose, microcephaly, high forehead with prominent glabella, hypertelorism, highly arched eyebrows, short philtrum, downturned mouth and micrognathia, among others), pre and postnatal growth retardation, hypotonia and developmental delay. Patients can also have epilepsy and abnormalities that involve other organs. Diagnosis can be made by conventional cytogenetic analysis which detects most of the cases. Treatment includes rehabilitation, speech therapy, antiepileptic drugs when necessary, gavage feeding or gastrostomy for feeding difficulties and standard management of other anomalies. 10 month-old female who presents characteristic craniofacial anomalies, clubfeet, hypotonia, gastroesofageal reflux, epilepsy, growth retardation and developmental delay. Diagnosis was confirmed by detection of a deletion of 4p that involved the critical region of the syndrome. This patient receives rehabilitation, antireflux medication and valproic acid. This condition must be recognized by pediatricians in order to offer adecuated management to these patients and their families.

Influência do tratamento intradisciplinar no desenvolvimento motor na síndrome de wolf-hirschhorn: estudo de caso / Influence of the intradisciplinary team on the motor development in wolf-hirschhorn syndrome: case study

A Síndrome de Wolf-Hirschhorn (SWH) é uma desordem genética incomum, com incidência de 1:50.000 nascidos vivos, descrita pela primeira vez por Hirschhorn, Cooper e Firschein, em 1961. Resulta da microdeleção distal do braço curto do cromossomo 4, mais especificamente em 4p16.3. A condição é normalmente associada com complexa expressão fenotípica que inclui malformações múltiplas com características crânio-facial típicas, e é caracterizada por atraso no desenvolvimento neuropsicomotor (DNPM), retardo mental e de crescimento, microcefalia, hipotonia muscular congênita, crises convulsivas, cardiopatias cong6nitas e anomalias renais, esqueléticas e oftálmicas. Esta pesquisa constitui-se no estudo de um caso relativo a uma criança com a SWH, seis anos e nove meses de idade, sexo masculino, que apresenta, além das características fenotípicas, atraso no DNPM, com a finalidade de verificar a influência da atuação da equipe intra-disciplinar no seu crescimento e desenvolvimento. Para a avaliação do paciente utilizou-se o Teste de Desenvolvimento de Denver, no qual apresentou desenvolvimento m6dio compatível com a idade de seis meses, e o Cartão de Desenvolvimento Neurológico, que também evidenciou atraso no DNPM. A atuação intra-disciplinar - participação conjunta de médicos, fisioterapeuta, terapeuta ocupacional e fonoaudiólogo - trouxe benefícios significativos, visto que a evolução do paciente foi superior a esperada em relação aos relatos da literatura.

The Wolf-Hirschhorn Syndrome (WHS) is an unusual genetic disorder with an incidence of 1 in 50,000 births. It was first described by Hirschhorn, Cooper and Firschein in 1961, and it results from the deletion of the distal short arm of chromosome 4, more specifically 4p 16.3. This condition is normally associated with a complex phenotypic expression that includes multiple malformations with typical cranio¬facial features. It is characterized by delayed neuropsychomotor development (NPMD), severe mental and growth retardation, microcephaly, congenital muscular hypotonia, seizures, congenital heart defect, ophthalmic, skeletal and renal disorders. This paper is a case study involving a male child aged six years and eleven months old, with WHS, presenting all the phenotypic features and NPMD retardation as well. The research intended to verify the influence of the intradisciplinary team on the growth and development of this child. Patient was evaluated with Denver Test of Development, in which presented an average development compatible with a 6-month-old child, and the Neurological Development Card, which resulted in NPMD retardation as well. The actuation of the intradisciplinary team - including physicians. physiotherapists, occupational therapists and speech therapists - has presented very beneficial results, since the patient's evolution was much superior than the expected considering literature reports.

O caso apresentado foi diagnosticado com base em critérios clínicos, radiológicos, ecodopplercardiogáficos e confirmado pelo resultado do cariótipo: 46,XX,del(4)(p15?1).

A case of Deletion of Chromosome 4p / 대한산부인과학회잡지

We have known that deletion of chromosomal 4p resulted Wolf-Hirschhorn syndrome. Wolf-Hirschhorn syndrome, first described in 1965 by Wolf et al and Hirschhorn et al, is defined multiple congenital anomalies and mental retardation syndrome resulting from deletion involving chromosomal band 4p. The main features of this syndrome are microcephaly, frontal bossing, dolycocephaly, hypoplasia of the eye socket, ptosis, strabismus, nystagmus, bilateral epicanthic folds, cleft lip, palate, beaked nose, hypospadias, cardiac malformations and mental retardation (IQ 20-30). As we experience a case of deletion of chromosome 4p by doing cytogenetic study due to abscence of fetal stomach on sonography and increased fetal nuchal folds, we report our case with a literature review.

A Case of Wolf-Hirschhorn Syndrome with Long Term Survival Diagnosed by Fluorescent In-situ Hybridization (FISH)

Wolf-Hirschhorn syndrome is a multiple malformation syndrome associated with mental and developmental retardation, resulting from a deletion at the short arm of chromosome 4 (4p16.3). We report a 11-year-old girl with Wolf-Hirschhorn syndrome, who was presented with severe growth and mental retardation along with characteristic features-frontal bossing, hypertelorism, downslanting of the palpebral fissures and fishlike lips. The diagnosis was confirmed by fluorescent in-situ hybridization (FISH).
