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).

Submissions by phenotype

not provided Pathogenic:2
Pathogenic, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpJan 04, 2024This sequence change creates a premature translational stop signal (p.Arg167*) in the DFNB59 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in DFNB59 are known to be pathogenic (PMID: 17301963, 17718875). This variant is present in population databases (rs118203989, gnomAD 0.01%). This premature translational stop signal has been observed in individual(s) with autosomal recessive deafness (PMID: 17373699). ClinVar contains an entry for this variant (Variation ID: 1300). For these reasons, this variant has been classified as Pathogenic. -
Likely pathogenic, criteria provided, single submitterclinical testingGeneDxSep 11, 2024Nonsense variant predicted to result in protein truncation or nonsense mediated decay in a gene for which loss of function is a known mechanism of disease; This variant is associated with the following publications: (PMID: 25525159, 22530481, 27018795, 35052489, 21696384, 28964305, 28483220, 26226137, 23804846, 17373699) -
Rare genetic deafness Pathogenic:1
Pathogenic, criteria provided, single submitterclinical testingLaboratory for Molecular Medicine, Mass General Brigham Personalized MedicineJun 01, 2020The p.Arg167X variant in DFNB59 has been reported in 2 individuals with hearing loss (1 Turkish and 1 Iranian), and segregated with disease in at least 1 affected family member (Collin 2007, Akhtarkhavari 2014). All affected individuals were homozygous. This variant has been identified in 0.01% (18/128640) of European chromosomes by gnomAD (http://gnomad.broadinstitute.org). Although this variant has been seen in the general population, its frequency is low enough to be consistent with a recessive carrier frequency. This nonsense variant leads to a premature termination codon at position 167, which is predicted to lead to a truncated or absent protein. In summary, this variant meets criteria to be classified as pathogenic for autosomal recessive hearing loss. ACMG/AMP Criteria applied: PVS1, PM2_Supporting, PM3, PP1_Supporting. -
