RCV001195541 | SCV001365922 | pathogenic | Rare genetic deafness | 2019-12-23 | criteria provided, single submitter | clinical testing | The p.Gln139X variant in OTOG has been reported by our laboratory in 1 individual with hearing loss who harbored the c.2116+5G>C variant of uncertain significance in trans. The p.Gln139X variant is absent from large population studies. This nonsense variant leads to a premature termination codon at position 139, 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, although additional studies are required to fully establish its clinical significance, this variant meets criteria to be classified as pathogenic for autosomal recessive hearing loss.
