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).

The Arg18Ile variant in DFNB59 has not been reported in the literature nor previ ously identified by our laboratory. Computational analyses (biochemical amino ac id properties, conservation, AlignGVGD, PolyPhen2, and SIFT) suggest that the Ar g18Ile variant may impact the protein, though this information is not predictive enough to determine pathogenicity. In summary, additional information is needed to fully assess the clinical significance of the Arg18Ile variant. -
