The p.Gly1674X variant has also been reported by other clinical laboratories in ClinVar (Variation ID 623765) and has been identified in 0.02% (14/70668) of European chromosomes by gnomAD (http://gnomad.broadinstitute.org). This nonsense variant leads to a premature termination codon at position 1647, which is predicted to lead to a truncated or absent protein. Loss of function of the OTOG gene is an established disease mechanism in autosomal recessive hearing loss. In summary, this variant meets criteria to be classified as pathogenic for autosomal recessive hearing loss. ACMG/AMP Criteria applied: PVS1, PM3, PM2_Supporting, PP1.
