Mapping of DFNB3/MYO15A in Punjabi families with non-syndromic congenital deafness.

Mapping of DFNB3/MYO15A in Punjabi families with non-syndromic congenital deafness

Deafness is inherited most commonly following autosomal recessive mode of inheritance as isolated clinical finding .Genetic and clinical heterogeneity of disorder prevent pooling of affected families and is a big barrier in gene mapping by conventional techniques. However, because of consanguinity, linkage analysis can be used to find disease causing loci /genes in small nuclear families. This ...

CNV Analysis Using Multiplex Ligation-Dependent Probe Amplification in Iranian Families with Non-Syndromic Congenital Heart Defects: Early Diagnosis of Non-Syndromic Patients

Background and Aims: Congenital heart defects (CHD) are the most common type of congenital disability. Copy number variations (CNVs) have been found as one of the genetic etiology of non-syndromic CHD, and researchers have detected several pathogenic CNVs in patients with cardiac defects. Materials and Methods: In the present study, 70 patients with familial (20 patients) and sporadic (50 pati...

Whole Exome Sequencing Identifies New Causative Mutations in Tunisian Families with Non-Syndromic Deafness

Identification of the causative mutations in patients affected by autosomal recessive non syndromic deafness (DFNB forms), is demanding due to genetic heterogeneity. After the exclusion of GJB2 mutations and other mutations previously reported in Tunisian deaf patients, we performed whole exome sequencing in patients affected with severe to profound deafness, from four unrelated consanguineous ...

Investigating Seven Recently Identified Genes in 100 Iranian Families with Autosomal Recessive Non-syndromic Hearing Loss

Objectives: Hearing loss (HL) is the most common sensory disorder, and affects 1 in 1000 newborns. About 50% of HL is due to genetics and 70% of them are non-syndromic with a recessive pattern of inheritance. Up to now, more than 50 genes have been detected which are responsible for autosomal recessive non-syndromic hearing loss, (ARNSHL). In  Iran, HL is one of the most common disabilitie...
