Screening of DFNB3 in Iranian families with autosomal recessive non-syndromic hearing loss reveals a novel pathogenic mutation in the MyTh4 domain of the MYO15A gene in a linked family

Objective(s): Non-syndromic sensorineural hearing loss (NSHL) is a common disorder affecting approximately 1 in 500 newborns. This type of hearing loss is extremely heterogeneous and includes over 100 loci. Mutations in the GJB2 gene have been implicated in about half of autosomal recessive NSHL (ARNSHL) cases, making this the most common cause of ARNSHL. For the latter form of deafness, most f...

Spongious hypertrophic cardiomyopathy in patients with mutations in the four-and-a-half LIM domain 1 gene.

BACKGROUND X-linked myopathy with postural muscle atrophy is a novel X-linked myopathy caused by mutations in the four-and-a-half LIM domain 1 gene (FHL1). Cardiac involvement was suspected in initial publications. We now systematically analyzed the association of the FHL1 genotype with the cardiac phenotype to establish a potential cardiac involvement in the disease. METHODS AND RESULTS Seve...

Autosomal Recessive Hypohidrotic Ectodermal Dysplasia Caused by a Novel Mutation in EDAR Gene

Backgrounds: Hypohidrotic ectodermal dysplasia (HED) is a rare genetic disorder, distinguished by hypotrichosis, hypohidrosis, and hypodontia. HDE can be inherited in X-linked recessive manner as a result of mutations in the ectodysplasin A (EDA) gene as well as autosomal dominant and autosomal recessive manners both of them caused by mutations in EDA receptor (EDAR) and EDAR-associated death d...

A New Mutation Causing Severe Infantile-Onset Pompe Disease Responsive to Enzyme Replacement Therapy

Pompe disease (PD), also known as “glycogen storage disease type II (OMIM # 232300)” is a rare autosomal recessive disorder characterized by progressive glycogen accumulation in cellular lysosomes. It ultimately leads to cellular damage. Infantile-onset Pompe disease (IOPD) is the most severe type of this disease and is characterized by severe hypertrophic cardiomyopathy and generalized hypoton...
