Abstract

Mutations in PJVK, encoding Pejvakin, cause autosomal recessive nonsyndromic hearing loss in humans at the DFNB59 locus on chromosome 2q31.2. Pejvakin is involved in generating auditory and neural signals in the inner ear. We have identified a consanguineous Pakistani family segregating sensorineural progressive hearing loss as a recessive trait, consistent with linkage to DFNB59. We sequenced PJVK and identified a novel missense mutation, c.1028G>C in exon 7 (p.C343S) co-segregating with the phenotype in the family. The p.C343 residue is fully conserved among orthologs from different vertebrate species. We have also determined that mutations in PJVK are not a common cause of hearing loss in families with moderate to severe hearing loss in Pakistan. This is the first report of PJVK mutation in a Pakistani family and pinpoints an important residue for PJVK function.
