Compound Heterozygous VSX2 Mutation Causing Bilateral Anophthalmia in a Consanguineous Egyptian Family

Purpose: To report the clinical and genetic study of a child with bilateral anophthalmia. Methods: A 14-year-old Egyptian boy, born from consanguineous parents, underwent a general and a full ophthalmological examination. Mutation screen of the A/M genes with recessive inheritance was done stepwise and DNA was analyzed by Sanger sequencing. Results: Bilateral anophthalmia, arachnodactyly of the...

Novel compound heterozygous mutations of ALDH1A3 contribute to anophthalmia in a non-consanguineous Chinese family

Anophthalmia is a rare eye development anomaly resulting in absent ocular globes or tissue in the orbit since birth. Here, we investigated a newborn with bilateral anophthalmia in a Chinese family. Exome sequencing revealed that compound heterozygous mutations c.287G > A (p.(Arg96His)) and c.709G > A (p.(Gly237Arg)) of the ALDH1A3 gene were present in the affected newborn. Both mutations were a...

A Novel Missense Mutation in the ALDH13 Gene Causes Anophthalmia in Two Unrelated Iranian Consanguineous Families

Anophthalmia or microphthalmia (A/M) is a rare group of congenital/developmental ocular malformations, characterized by absent or small eye within the orbit affecting one or both eyes. It  has complex etiology with chromosomal, monogenic with high heterogeneity, and environmental causes. We performed genome SNP-array analysis followed by autozygosity mapping and sequencing in the members o...

A novel compound heterozygous mutation in the GJB2 gene causing non-syndromic hearing loss in a family

Mutations in the GJB2 gene are responsible for up to 50% of cases of non-syndromic recessive hearing loss, with c.35delG, c.167delT and c.235delC being the predominant mutations in many world populations. However, a large number of rare mutations in this gene may also contribute to hearing loss. The aim of the present study was to conduct a clinical and molecular characterization of a Chinese f...

A Compound Heterozygous HPD Mutation in an Iranian Patient with Hypertyrosinemia Type III

Background and Aims: Hypertyrosinemia type 3 (HT3) is an inherited error in tyrosine metabolism caused by a mutation in the 4-hydroxyphenylpyruvate dioxygenase (HPD) gene. Here we report a one and half-year-old girl infant who was diagnosed based on increased serum tyrosine levels and increased urinary excretion of p-hydroxyphenyl derivatives. Materials and Methods: The proband was one and ha...
