Genetic and molecular analysis of the CLDN14 gene in Moroccan family with non-syndromic hearing loss.

ABSTRACT:

Background

Hearing loss is the most prevalent human genetic sensorineural defect. Mutations in the CLDN14 gene, encoding the tight junction claudin 14 protein expressed in the inner ear, have been shown to cause non-syndromic recessive hearing loss DFNB29.

Aim

We describe a Moroccan SF7 family with non-syndromic hearing loss. We performed linkage analysis in this family and sequencing to identify the mutation causing deafness.

Materials and methods

Genetic linkage analysis, suggested the involvement of CLDN14 and KCNE1 gene in deafness in this family. Mutation screening was performed using direct sequencing of the CLDN14 and KCNE1 coding exon gene.

Results

Our results show the presence of c.11C>T mutation in the CLDN14 gene. Transmission analysis of this mutati
