Laboratory for Molecular Medicine, Partners HealthCare Personalized Medicine RCV000614011 SCV000712281 likely pathogenic Rare genetic deafness 2016-06-27 criteria provided, single submitter clinical testing The p.Arg1165X variant in OTOG has not been reported in individuals with hearing loss. Data from large population studies are insufficient to assess the frequen cy of this variant. This nonsense variant introduces a premature termination cod on at position 1165, which is predicted to lead to a truncated or absent protein . Two loss of function variants in the OTOG gene have been reported to segregate with hearing loss in two families (Schraders 2012), and disruption of OTOG in m ice resulted in deafness supporting a loss-of-function mechanism for the disease (Simmler 2000). In summary, although additional evidence is required to strengt hen the association between OTOG and hearing loss, available data support that t he p.Arg1165X variant is likely pathogenic.
