Analysis of FGD1 gene variant in a child with Aarskog-Scott syndrome / 中华医学遗传学杂志

OBJECTIVE@#To detect pathogenic variant of the FGD1 gene in a boy with Aarskog-Scott syndrome.@*METHODS@#Genetic variant was detected by high-throughput sequencing. Suspected variant was verified by Sanger sequencing. The nature and impact of the candidate variant were predicted by bioinformatic analysis.@*RESULTS@#The child was found to harbor a novel c.1906C>T hemizygous variant of the FGD1 gene, which has led to conversion of Arginine to Tryptophane at codon 636(p.Arg636Trp). The same variant was found in his mother but not father. Based on the American College of Medical Genetics and Genomics guidelines, the c.1906C>T variant of FGD1 gene was predicted to be likely pathogenic(PM1+PM2+PM5+PP2+PP3+PP4).@*CONCLUSION@#The novel c.1906C>T variant of the FGD1 gene may underlay the Aarskog-Scott syndrome in this child. Above finding has enabled diagnosis for the boy.

Genetic analysis of a Chinese pedigree affected with congenital split-hand/foot malformation / 中华医学遗传学杂志

OBJECTIVE@#To analyze the molecular genetics of a Chinese pedigree with congenital hand foot cleft.@*METHODS@#Single nucleotide polymorphism microarray (SNP array) was used to analyze the whole genome copy number variation.@*RESULTS@#SNP array analysis showed that there was a 433 kb repeat in 10q24.31-10q24.32 region, which contained LBX1, BTRC, POLL, OPCD and FBXW4 genes.@*CONCLUSION@#Microduplication of chromosome 10q24.31-10q24.32 may be the cause of congenital hand foot cleft in this pedigree.

Vohwinkel syndrome: ichthyosiform variant in a family

Abstract: Vohwinkel syndrome belongs to the group of hereditary palmoplantar keratoderma, having an autosomal dominant inheritance. In this report, the authors present a case of a four-year-old boy with diffuse scaling over his entire body and transgredient palmoplantar hyperkeratosis with some fissured areas. Family evaluation revealed that his mother and other family members were affected. Based on his clinical findings and on family history, the diagnosis of the ichthyotic Vohwinkel syndrome subtype, characterized by generalized ichthyosis and palmoplantar hyperkeratosis, was established.

RESUMO Relatamos um caso de duas irmãs, filhas de pais consanguíneos, apresentando uma condição semelhante de baixa acuidade visual associado à distrofia retiniana em ambos os olhos associado à alopecia e alterações ósseas ou sindactilia.

Vohwinkel syndrome, ichthyosiform variant - by Camisa - Case report / Sindrome de Vohwinkel, variante ictiosiforme - de Camisa - Relato de caso

Vohwinkel syndrome or keratoderma hereditaria mutilans is a rare autosomal dominant palmoplantar keratosis, which manifests in infants and becomes more evident in adulthood. Its mode of inheritance is autosomal dominant with mutation in loricrin and Connexin 26 genes. Patients with this mutation present hyperkeratosis of the palms and soles, constricting bands of the digits, usually on the fifth, and starfish-shaped hyperkeratosis on the dorsal aspects of the hands and feet. The disease mostly occurs in white women, where constricting fibrous bands appear on the digits and can lead to progressive strangulation and auto-amputation (pseudo-ain-hum).The authors report a rare case of a patient with a clinical ichthyosiform variant of Vohwinkel syndrome.

A síndrome de Vohwinkel ou queratodermia hereditária mutilante é uma queratose palmo-plantar rara, autossômica dominante, que se manifesta em crianças e se torna mais evidente na vida adulta. Seu modo de herança é autossômica dominante com mutação na loricrina e no gen da Conexina 26. Os pacientes com esta mutação apresentam hiperqueratose das palmas das mãos e plantas dos pés, com bandas constritivas dos dígitos, normalmente no quinto dedo e hiperqueratose em forma de estrela do mar nas regiões dorsais das mãos e dos pés. A doença ocorre principalmente em mulheres brancas, onde as bandas constritivas fibrosas aparecerem nos dígitos e podem levar ao estrangulamento progressivo e auto-amputação (pseudo-ainhum).Os autores relatam o caso de uma variante ictiosiforme da síndrome de Vohwinkel.

Association of generalized aggressive periodontitis and ectrodactyly-ectodermal dysplasia-cleft syndrome.

Ectrodactyly-ectodermal dysplasia-cleft (EEC) syndrome is an autosomal dominant disorder characterized by the triad of ectrodactyly, ectodermal dysplasia, and facial clefting. Even though literature has documented the association of various genetic disorders with aggressive periodontitis, the periodontal manifestations in patients with EEC syndrome have never been addressed. This case report presents the periodontal status of three patients in a family with EEC syndrome. The presence of generalized aggressive periodontitis was noticed in these patients. EEC syndrome could be a new addition to the group of genetic disorders associated with aggressive periodontitis.

Familial clustering of a rare syndrome.

Ectrodactyly, ectodermal dysplasia and cleft palate syndrome is a rare autosomal dominant multiple congenital anomaly syndrome with variable expressivity and reduced penetration. The cardinal features are cleft palate/lip, lobster hand deformity, sparse hypopigmented hair, dry scaly skin, and lacrimal and urogenital anomalies. A neonate presented to us with typical features, his mother and other two siblings were also affected.

Ectrodactyly/split hand feet malformation.

Split-hand/split-foot malformation is a rare limb malformation with median clefts of the hands and feet and aplasia/hypoplasia of the phalanges, metacarpals and metatarsals. When present as an isolated anomaly, it is usually inherited as an autosomal dominant form. We report a case of autosomal recessive inheritance and discuss the antenatal diagnosis, genetic counseling and treatment for the malformation.

Displasia ectodérmica, ectrodactilia e fissura lábio-palatal: manifestações oculares da síndrome em relato de caso / Ectodermal dysplasia, ectrodactyly and clefting syndrome: ocular manifestations of this syndrome in a case report

Descrição de um caso da síndrome de displasia ectodérmica, ectrodactilia e fissura lábio-palatal (EEC), doença rara com importante acometimento ocular. Paciente de 26 anos, com queixa de dor, fotofobia e baixa acuidade visual no olho esquerdo há três dias, submetida à investigação genética, após exames físico e oftalmológico completos. Foi diagnosticado síndrome EEC e identificadas todas as alterações sistêmicas e oculares. Apresentava uma úlcera paracentral estéril no olho esquerdo, com dificuldades de cicatrização devido às alterações oculares próprias da síndrome (alteração do filme lacrimal, triquíase, ausência de glândulas de Meibomius, entre outras). Foi feita descrição das alterações oculares nessa síndrome rara, para que haja tratamento preventivo e diminuam os riscos de baixa de acuidade visual em pacientes que recebam esse diagnóstico genético.

A case of ectodermal dysplasia, ectrodactyly and clefting syndrome (EEC), a rare disease with an important ocular impairment and with scarce literature. Patient, 26 years old with complaints of pain, with photophobia and low visual acuity in the left eye for three days. The patient was submitted to a genetic investigation after complete physical and ophthalmologic examinations. EEC syndrome was diagnosed and all systemic and ocular modifications identified. The patient presented a scar in the left eye, with difficulties in healing due to ocular damage caused by the syndrome (lack of tear film, trichiasis, Meibomius gland absence, among others). The ocular modifications in this rare syndrome were described in order to institute preventive treatment and to reduce the risks of low visual acuity in patients who receive this genetic diagnosis.

A síndrome de Holt-Oram revisitada: dois casos em uma mesma família / Holt-Oram syndrome revisited: two patients in the same family

Holt-Oram syndrome was first described in 1960 as an association of familial heart disease and musculoskeletal abnormalities. The most important findings include atrial septal defects, atrioventricular conduction abnormalities, vascular hypoplasia, and upper limb musculoskeletal deformities. We report two patients with this syndrome in the same family and discuss the variability of the musculoskeletal abnormalities and their association with the cardiac morphologic defects. Both patients in this study had associated eosinophilia, which has not been reported in the literature.
