Genes affected

PJVK (HGNC:29502): (pejvakin) The protein encoded by this gene is a member of the gasdermin family, a family which is found only in vertebrates. The encoded protein is required for the proper function of auditory pathway neurons. Defects in this gene are a cause of non-syndromic sensorineural deafness autosomal recessive type 59 (DFNB59).

Apr 27, 2017

This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). No publications were found based on this search. Allele frequency data from public databases did not allow this variant to be ruled in or out of causing disease. Therefore, this variant is classified as a variant of unknown significance. -

Thr135Thr in Exon 3 of DFNB59: This variant is not expected to have clinical sig nificance because it does not alter an amino acid residue and, although it is lo cated 3 bp away from the exon/intron junction, computational tools do not sugges t an impact to splicing. The variant has been identified in 0.03% (3/8600) of E uropean American chromosomes by the NHLBI Exome Sequencing Project (http://evs.g s.washington.edu/EVS/; dbSNP rs20098046). -
