GeneDx RCV000152153 SCV000618173 uncertain significance not specified 2017-09-15 criteria provided, single submitter clinical testing The E2246K variant in the TRIOBP gene has been reported previously in an individual with hearing loss who also harbored two additional variants in the TRIOBP gene reported to be in trans with E2246K, however, familial segregation information was not included (Sloan-Heggen et al., 2016). The E2246K variant is observed in 457/50,286 (0.91%) alleles from individuals of non-Finnish European background in large population cohorts (Lek et al., 2016). In addition, this variant has been detected in the homozygous state in three presumably healthy individuals undergoing testing at GeneDx. The E2246K variant is a non-conservative amino acid substitution, which is likely to impact secondary protein structure as these residues differ in polarity, charge, size and/or other properties. This substitution occurs at a position where amino acids with similar properties to Glutamic Acid are tolerated across species. In silico analysis predicts this variant is probably damaging to the protein structure/function. We interpret E2246K as a variant of uncertain significance.
