ABSTRACT

OBJECTIVE@#To explore the clinical and genetic characteristics of a child with X-linked hypohidrotic ectodermal dysplasia (XLHED).@*METHODS@#Clinical data of the child was collected. Peripheral blood samples were taken from the child and his parents with informed consent and subjected to copy number variation (CNV) analysis and whole exome sequencing (WES).@*RESULTS@#The male infant manifested sparse hair, anhidrosis, anuresis due to polycystic kidney dysplasia, external genital malformation and anal atresia. WES has revealed a 406 bp hemizygous deletion at Xq13 (68 836 147-68 836 553) in the proband, which encompassed exon 1 of the EDA gene. A heterozygous deletion at the same site was detected in the mother, while no deletion or duplication of the site was detected in the father.@*CONCLUSION@#The hemizygous deletion of EDA gene exon 1 probably underlay the ectodermal dysplasia in the proband. Above result has provided a basis for genetic counseling and prenatal diagnosis for the family.

ABSTRACT

OBJECTIVE@#To investigate the clinical phenotype and genetic characteristics of a patient with hypohidrotic ectodermal dysplasia (HED) due to partial deletion of EDA gene.@*METHODS@#The child has presented with HED complicated with epilepsy. Family trio whole exome sequencing (Trio-WES), copy number variation sequencing (CNV-seq), and karyotype analysis were carried out to explore the underlying genetic etiology.@*RESULTS@#The proband, a 7-year-and-8-month-old boy, presented with thin curly hair, thin and sparse eyebrow, xerosis cutis, susceptibility to hyperthermia from childhood, hypohidrosis, sharp/sparse/absent teeth, saddle nose, prominent forehead, auricle adulation and seizure. He was found to have a normal chromosomal karyotype, and no abnormality was found by Trio-WES. Genome-wide CNV-seq revealed a 341.90 kb deletion at Xq13.1q13.1 (chrX: 68 796 566-69 138 468). As verified by PCR-electrophoresis, the deletion has removed part of the EDA gene. The deletion was derived from his mother with normal hair, mild xerosis cutis, and sparse, decidulated and nail-like teeth. The mother was detected with a heterozygous 242.10 kb deletion at Xq13.1q13.1 (chrX: 68 836 154-69 078 250).@*CONCLUSION@#Both the proband and his mother have carried a Xq13.1 microdeletion involving part of the EDA gene. The clinical phenotypes of the mother and the proband were consistent with the clinical characteristics of X-linked recessive HED, for which partial deletion of the EDA gene is probably accountable.

ABSTRACT

Cardio-facio-cutaneous (CFC) syndrome is an extremely rare autosomal dominant genetic disease due to BRAF and other gene mutations. The main characteristics of the patients are craniofacial deformities, cardiac malformations, skin abnormalities, delay of language and motor development, gastrointestinal dysfunction, intellectual disability, and epilepsy. In this case, the child has a typical CFC syndrome face and developmental delay. The gene results of the second-generation sequencing technology showed that there was a mutation site c.1741A>G (p. Asn581Asp) (heterozygous) in exon 14 of the BRAF (NM_004333.5) gene. The mutation was not observed in the child's parents. The above-mentioned mutation may be a de novo mutation. There is no effective therapy for this disease so far.

ABSTRACT

Resumen El síndrome de Ellis van Creveld es un trastorno autosómico recesivo, caracterizado por mutaciones en los genes ECV y ECV2, los cuales son importantes para el desarrollo osteocondral. A nivel mundial, se han reportado aproximadamente 300 casos ,presentándose con mayor frecuencia en poblaciones endogámicas. Se caracteriza por distrofias óseas, displasias ectodérmicas y malformaciones cardíacas. El diagnóstico clínico puede ser confirmado mediante pruebas moleculares. A continuación, se presenta el caso de una paciente diagnosticada con el síndrome, la cual fue evaluada de manera interdisciplinaria. Esta revisión permitió dar a conocer un nuevo caso de la patología, relacionar las manifestaciones clínicas de la paciente con la literatura y describir nuevos hallazgos que pueden correlacionarse con el síndrome.


Abstract Ellis Van Creveld syndrome is an autosomal recessive disorder, characterized by mutations of the genes ECV and ECV2, which are very important in the osteochondral development. Worldwide, there have been reported around 300 cases that are commonly evidenced in populations where endogamy is typical. It is clinically characterized by bone dystrophies, ectodermal dysplasias, and congenital heart defects; the diagnosis can be confirmed by molecular tests. In the lines below, a case of a patient that suffers from this syndrome, and that was examined in an interdisciplinary way will be presented. This review allows us to show a new case of this pathology, to relate the clinical symptoms of the patient with the existing literature, and to describe new findings that can be correlated with the Ellis Van Creveld condition.

ABSTRACT

OBJECTIVE@#To explore the genetic cause of a patient suspected for congenital ectodermal dysplasia with repeated hyperthermia and to assess the reproductive risk for his family.@*METHODS@#Medical whole-exome sequencing (WES) were used to detect single-nucleotide variations and low-coverage massively parallel copy number variation sequencing (CNV-seq) were employed to verify suspected CNVs. PCR and real-time quantitative PCR were applied to confirm the deletion of EDA gene.@*RESULTS@#The results of WES suggested that the patient carried a hemizygous deletion for chrX:69 243 016-69 395 730. CNV-seq indicated that the patient carried a deletion of approximately 0.12 Mb on Xq13.1, which encompassed the EDA gene. The PCR results confirmed that there was a hemizygous deletion of exons 3 to 8 of the EDA gene. The same deletion was not found in his mother.@*CONCLUSION@#The congenital ectodermal dysplasia of the patient may be attributed to deletion of exons 3 to 8 of the EDA gene, which could be de novo or derive from germline mosaicism of his mother. The WES and CNV-seq are of great value for the diagnosis of rare diseases.

ABSTRACT

OBJECTIVE@#To explore the genotype-phenotype correlation of Cardio-facio-cutaneous syndrome (CFCS) caused by MAP2K1 gene variants.@*METHODS@#Genomic DNA was extracted from peripheral blood sample from a child patient and his parents. Whole exome sequencing (WES) was carried out for the patient. Suspected variant was verified by Sanger sequencing.@*RESULTS@#The patient was a 1-year-8-month old Chinese male who manifested short stature, psychomotor retardation, relative macrocephaly, distinctive facial features, and congenital heart disease. WES test revealed a heterozygous missense c.389A>G (p.Tyr130Cys) variant in the MAP2K1 gene. Sanger sequencing has confirmed the variant as de novo. According to ACMG/AMP guidelines, the variant was classified as pathogenic.@*CONCLUSION@#Compared with previously reported CFCS cases due to MAP2K1 variants. The patient showed obvious behavioral problems, good appetite and tricuspid regurgitation, which may to be novel features for CFCS.

ABSTRACT

RESUMEN Las displasias ectodérmicas constituyen alteraciones de los derivados embriológicos del ectodermo. Paciente adulta, con hipoparatiroidismo, llamó la atención por su fenotipo y fue remitida de la consulta de Neurología a la consulta Genética. Se diagnosticó una displasia ectodérmica hipohidrótica, de origen genético con herencia autosómica dominante, poco común para esta entidad. Se presenta este caso con el objetivo de describir las manifestaciones clínicas de esta alteración genética, las cuales nunca fueron objeto de interés médico resultando inadvertidas para su estudio y diagnóstico. Esta alteración se asocia a una condición patológica como el hipoparatiroidismo, en la literatura revisada no se encontraron reportes de la misma. La evaluación clínica de la paciente permitió hacer el diagnóstico y explicar muchos de los problemas para los cuales no existían respuestas, así como ofrecer un asesoramiento genético adecuado para ella y para sus familiares con riesgo de padecer una condición genética similar.


ABSTRACT Ectodermic dysplasias are alterations of the ectoderm embryologic derivatives. This is a case of an adult female patient with hypoparathyroidism, drawing attention due to her phenotype; she was remitted by the consultation of Neurology to the Genetic one. She was diagnosed a hypohidrotic ectodermal dysplasia, of genetic origin with autosomal dominant inheritance, what is very rare for this entity. The case is presented with the aim of describing the clinical manifestation of this genetic alteration that never drew medical interest and nobody diagnosed or studied. It is associated to a pathologic condition like hypothyroidism and was not reported in medical literature before. The clinical evaluation of the patient allowed arriving to the diagnostic and explaining many problems that were unexplained, and also offering the adequate genetic advice to her and her relatives likewise at risk of suffering a similar genetic condition.

ABSTRACT

Anhidrotic ectodermal dysplasia (AED) is a rare hereditary disorder with a triad of sparse hair, dental hypoplasia, and anhidrosis. Here we report a case of AED with food allergy and atopic eczema. The patient was a 11-month-old boy admitted to our hospital with pyrexia for 2 weeks. He presented with a history of dry skin, eczema, and food allergy to egg. On clinical examination, his body temperature was 38.8°C, with dry skin and eczema almost all over the body, sparse eyebrows, and scalp hair. Laboratory investigations and physical examination did not show any evidence of infection. Radioallergosorbent test was positive to egg yolk, egg white, ovomucoid, milk, house dust, and house dust mite. As the child did not sweat despite the high fever, we performed the sweat test which revealed a total lack of sweat glands. Genetic examination revealed a mutation of the EDA gene and he was diagnosed as AED. His pyrexia improved upon cooling with ice and fan. His mother had lost 8 teeth and her sweat test demonstrated low sweating, suggestive of her being a carrier of AED. Atopy and immune deficiencies have been shown to have a higher prevalence in patients with AED. Disruption of the skin barrier in patients with AED make them more prone to allergic diseases such as atopic eczema, bronchial asthma, allergic rhinitis and food allergy. Careful assessment of the familial history is essential to differentiate AED when examining patients with pyrexia of unknown origin and comorbid allergic diseases.

ABSTRACT

Ectodermal Dysplasia (ED) represents a group of hereditary conditions in which anatomical structures derived from the ectoderm show defects in its development. It is observed aplasia or hypoplasia of the tissues, among them the changes of dental relevance, as the anomalies regarding the number and morphology of the teeth. Due to the particularity of the cases, the dental surgeon must adapt the operative techniques and the choice of dental materials to each individual, according to the perceived need and condition. The objective of the present study is to report the clinical case of a 10 - year old male patient with ectodermal dysplasia who was attended in the discipline of Patients with Special Needs of Dentistry of the Federal University of Fluminense and its multidisciplinary aspects. (AU)


A Displasia Ectodérmica (DE) representa um grupo de condições hereditárias em que estruturas anatômicas derivadas do ectoderma apresentam defeitos em seu desenvolvimento. Observa-se aplasia ou hipoplasia dos tecidos, dentre eles as alterações de relevância dentária, como as anomalias quanto ao número e morfologia dos dentes. Devido à particularidade dos casos, o cirurgião-dentista deve adaptar as técnicas operatórias e a escolha dos materiais dentários a cada indivíduo, de acordo com a necessidade e condição percebida. O objetivo do presente estudo é relatar o caso clínico de um paciente do sexo masculino, de 10 anos de idade, portador de displasia ectodérmica, atendido na disciplina de Portadores de Necessidades Especiais de Odontologia da Universidade Federal Fluminense e seus aspectos multidisciplinares (AU)

ABSTRACT

La Aplasia Cutis Congénita es una afección in-frecuente caracterizada por la ausencia de piel al nacer. Su localización más frecuente es en vértex, siendo rara en miembros inferiores como es el caso de nuestra paciente. La misma puede presentarse de forma aislada o asociada a otras anomalías o alteraciones genéticas. Analizamos el caso de una paciente de sexo femenino, con antecedente de consumo de marihuana materno durante la gestación, que presenta una aplasia cutis congénita extensa de miembro inferior derecho con acorta-miento del mismo a expensas de partes blandas, sin otras anomalías asociadas a la que se le realizó tratamiento tópico con gel antiséptico y apósitos glicerinados estériles con buena evolución y sin complicaciones.


Aplasia Cutis Congenita is an infrequent condi-tion characterized by the absence of skin at birth. The most frequent location is the scalp, being rare in lower limbs as is the case of our patient. It can be an isolated condition or be associated with other anomalies or genetic disorders. We analyzed the case of a female patient, with a history maternal use of marijuana during pregnancy, who presented a congenital extensive aplasia cutis of the right lower limb, with shortening at the expense of soft parts, without other abnormalities associated, who received topical treatment with antiseptic gel and sterile glycerinated dressings with good evolution and without complications.

ABSTRACT

OBJECTIVE@#To detect pathogenic mutation of DOCK6 gene in a patient with convulsive seizure and refractory epilepsy.@*METHODS@#CytoScan HD-Array and next generation sequencing were used to detect the potential mutation in the patient.@*RESULTS@#The proband has carried compound heterozygous mutations of c.188C>T (p.Arg63Gln) and c.5374C>T (p.Glu1792Lys) of the DOCK6 gene, which were respectively inherited from his mother and father. Neither mutation was reported previously. Bioinformatic analysis indicated that the two amino acids are highly conserved. Based on the ACMG guidelines, the c.188C>T mutation was predicted to be likely pathogenic, while the c.5374C>T mutation was of uncertain significance.@*CONCLUSION@#The compound heterozygous mutations of c.188C>T (p.Arg63Gln) and c.5374C>T (p.Glu1792Lys) of the DOCK6 gene probably underlie the disease in this patient.

ABSTRACT

We constructed lentiviral vectors containing the human wild-type GJB6 gene and the mutant variants A88V and G11R. The three proteins were stably expressed by the Tet-on system in the HaCaT cell line and used to study the functional effect of the variants. The CCK-8 assay and flow cytometric analyses were used to determine the levels of cell proliferation and apoptosis. Western blot analyses were performed to analyze the relevant clinical indicators of hidrotic ectodermal dysplasia and markers of apoptosis in transfected HaCaT cells. The CCK8 assay and the flow cytometry results showed a significant increase (P<0.05) in the apoptosis of HaCaT cells expressing the A88V and G11R mutants. In addition, we demonstrated that the A88V and G11R mutants induced the apoptosis of transfected HaCaT cells via the activation of caspase-3, -8, -9, and PARA. No change was observed in the activity of BAX compared with the control. This study provides further clarification on the mechanisms underlying the effect of the mutant variants A88V and G11R of the GJB6 gene on the induction of HaCaT cell apoptosis.

ABSTRACT

Dysphasia related to oral anomaly is a common situation in oral and maxillofacial surgery. The etiology of oral anomalies causing dysphasia can be divided into congenital and acquired disease. Congenital diseases include teratoma or benign tumors and congenital defects such as cleft lip and palate. Benign tumors include cystic hygroma in the neck and hemangioma in the tongue. Certain syndromes with macroglossia and micrognathia are also related to difficulty in swallowing. The three common syndromes are Pierre-Robin syndrome, Beckwith-Widermann syndrome and ectodermal dysplasia. Taken together, these congenital diseases require a multi-discipline approach to obtain optimal results. Representative disease of acquired dysphasia is the oral cavity cancer. Cancer ablation results in tissue defect and decreased motor function. Free flap reconstruction is the choice of treatment following oral cavity caner operation; however, dysphasia after cancer operation is inevitable. In this review article, the full scopes of oral anomaly associated with dysphasia were classified and treatment was suggested.

ABSTRACT

Ectodermal dyspasia (ED) is a hereditary disease that includes genetic and environmental changes. ED causes hypodontia, dystrophic nails, sparse hair and dental anomalies. Oral rehabilitation treatment for pediatric patients with ED is difficult because of continuous development and craniofacial growth. The aim of this study was to present a case report of oral rehabilitation in pediatric patients diagnosed with ED. A 5- year, 6-month-old girl reported to the clinic of Pediatric Dentistry in University Anhanguera UNIDERP-BR. Extraoral examination showed that the patient was an oral breather, and presented with decreased lower face height, protruding and everted lips, prominent forehead, "horse saddle" nose, lack of hair, eyelashes and eyebrows, thin and dry skin. Intraoral examination demonstrated absence of teeth: 51/52, 61/62/63, 71/72, 81/82 and tree conical teeth: 53, 73 and 83. The radiographic examination revealed agenesis of 9 primary teeth and of the buds of the following permanent teeth: 11/12/13, 21/22/23, 41/42, 31/32, we observed the presence of teeth buds of 33 and 43. Considering physical and radiographic characteristics hydrotic ectodermal was diagnosed. As clinical management, we opted for the installation of removable functional aesthetic maintainers, favoring the speech normality, swallowing, lip and lingual muscle tone and social development.


A displasia ectodérmica (DE) caracteriza-se por uma doença hereditária que consiste em alterações genéticas e ambientais, provocando hipodontia, unhas distróficas, cabelos escassos e anomalias dentárias. O tratamento reabilitador em pacientes pediátricos com DE se torna difícil devido ao contínuo desenvolvimento e crescimento crânio-facial dessas crianças. O presente trabalho tem como objetivo relatar um caso clínico de reabilitação oral em paciente pediátrico diagnosticado com DE. Paciente sexo feminino, com 5 anos e 6 meses de idade compareceu a clínica de Odontopediatria na UNIDERP. Ao exame físico, extra-oral, constatou-se que a paciente era respiradora bucal, e tinha como características a diminuição do terço inferior da face, lábios protusos e evertidos, fronte proeminente, nariz em "sela", escassez de pelos, cílios e sobrancelha, pele fina e seca. No exame intra-oral observou-se ausência dos elementos dentários, 51/52, 61/62/63, 71/72, 81/82, e os elementos 53, 73 e 83 apresentando aspecto conóide. Ao exame radiográfico constatou-se a agenesia de 9 dentes decíduos e dos germes dos seguintes dentes permanentes: 11/12/13, 21/22/23, 41/42, 31/32 e ainda observou-se a presença dos germes dos dentes 33 e 43. Baseado nas características físicas e radiográficas diagnosticou-se displasia ectodermica hidrótica. Como conduta clínica, optou-se pela instalação de mantenedores estéticos funcionais removíveis, favorecendo a normalidade da fala, deglutição, tonicidade muscular labial e lingual e do desenvolvimento social.

Presentamos el caso de un neonato sin antecedentes familiares ni prenatales de importancia, con peso bajo para la edad, fascies envejecida, puente nasal ancho, hipotricosis, piel descamativa, apergaminada, seca y hepatomegalia, aparente hipohidrosis con episodios de hipertermia, fenotipo compatible con displasia ectodérmica hipohidrótica, por alteraciones en la diferenciación y desarrollo de estructuras ectodérmicas: piel, pelo, dientes y glándulas sudoríparas, alteración en las señales entre ectodermo y mesénquima, además de mayor riesgo de desarrollar alteraciones inmunológicas y en la supresión de tumores. Este paciente requiere cuidados dérmicos y evitar la hipertemia que puede ocasionar un daño cerebral fatal, tratamiento dental precoz para restaurar la función, monitoreo permanente de función auditiva y oftálmica, consejo genético a la familia; y al asociarse con inmunodeficiencia puede requerir terapias de restitución inmune, tratamientos agresivos de las infecciones asociadas y/o un trasplante de células madre hematopoyéticas, según la evolución clínica.


This is the case of a newborn without family history of important diseases, with low weight for age, aged fascies, broad nasal bridge, hypotrichosis, desquamative skin, parchment, dry and hepatomegaly, apparent hypohidrosis with episodes of hyperthermia, phenotype compatible with dysplasia ectodermic hypohydrotic, by alterations in the differentiation and development of ectodermal structures: skin, hair, teeth and sweat glands, alteration in the signals between ectoderm and mesenchyme, as well as a greater risk of developing immunological alterations and tumor suppression. This patient requires dermal care and avoids the hyperthermia that can cause fatal brain damage, early dental treatment to restore function, permanent monitoring of auditory and ophthalmic function, genetic counseling to the family, and to associate with immunodeficiency, probably, requires therapies of immune restitution, aggressive treatments of associated infections and / or a transplant of hematopoietic stem cells, according to the clinical evolution.

ABSTRACT

RESUMO Objetivo: EEC é um acrônimo para uma síndrome autossômica dominante caracterizada clinicamente por ectrodactilia (E), displasia ectodérmica efissura labiopalatal (C). Nosso objetivo foi relatar um caso raro de irmãos afetados pela síndrome de ectrodactilia, displasia ectodérmica efissura labiopalatal (EEC) com pais hígidos. Descrição do caso: O paciente era o terceiro filho de pais jovens e hígidos, os quais não apresentavam nenhuma anomalia menor ou maior de mãos e pés ou anomalias de pele, cabelos e dentes. O casal tinha história prévia de duas crianças com malformação de mãos e pés, similar à do paciente. O primeiro foi natimorto e o segundo, prematuro, falecendo nos primeiros dias de vida, pelas consequências da prematuridade. Após o nascimento, o paciente apresentou desconforto respiratório, com necessidade de intubação orotraqueal e ventilação mecânica. No exame físico, verificaram-se a presença de fissura labiopalatal e ectrodactilia de mãos e pés, com ausência do segundo e terceiro dedos em ambas as mãos e defeitos de redução acometendo principalmente o segundo dedo dos pés. A criança apresentou pneumotórax e parada cardiorrespiratória, morrendo com 1 mês e 26 dias de vida. Comentários: Descrevemos aqui um caso de irmãos com síndrome EEC, indicativo de mosaicismo germinativo. Na revisão da literatura, observaram-se apenas três relatos similares. Este caso reforça a possibilidade do mosaicismo germinativo ser um mecanismo de herança mais comum do que se acreditava previamente para casos da síndrome EEC.


ABSTRACT Objective: EEC is an acronym for an autosomal dominant syndrome clinically characterized by ectrodactyly (E), ectodermal dysplasia (E) and cleft lip/palate (C). Our aim was to describe a rare case of siblings affected by ectrodactyly, ectodermal dysplasia and cleft lip/palate (EEC) syndrome presenting normal parents. Case description: The patient was the third son of young and healthy parents. The parents did not present any minor or major anomaly of hands, feet or skin, hair and teeth. The couple had a previous history of two children with hands and feet malformations similar to the present patient. The first was a stillborn, and the second one a preterm infant that died in the first days after birth due to the consequences of prematurity. After birth, the patient presented respiratory distress with need of endotracheal intubation and mechanic ventilation. At physical examination, there were cleft lip/palate, hands and feet ectrodactyly, with absence of the second and third fingers in both hands, and reduction defects affecting mainly the second toes. The child presented pneumothorax and cardiorespiratory arrest and died at 1 month and 26 days. Comments: Herein we described a case of siblings with EEC syndrome, indicative of a germline mosaicism. In the literature review, there was the description of only three similar reports. The present case strengthens the possibility that germline mosaicism may be a more common inheritance mechanism than previously thought in cases of EEC syndrome.
