Description

The R82H variant in the OTOF gene has not been reported previously as a pathogenic variant, nor as a benign variant, to our knowledge. It is reported as benign in ClinVar by a different clinical laboratory, but additional evidence is not available (ClinVar SCV000065194.4; Landrum et al., 2015). The R82H variant is observed in 50/7412 (0.68%) alleles from individuals of African background in the ExAC dataset, and no individuals were reported to be homozygous (Lek et al., 2016). The R82H variant is a conservative amino acid substitution, which is not likely to impact secondary protein structure as these residues share similar properties. This substitution occurs at a position that is not conserved across species. In silico analysis is inconsistent in its predictions as to whether or not the variant is damaging to the protein structure/function. We interpret R82H as a variant of uncertain significance.
