A variant of uncertain significance has been identified in the POLG gene. The R1006K variant has notbeen published as a pathogenic variant, nor has it been reported as a benign variant to our knowledge. This variant is observed in 1/10150 (0.01%) alleles from individuals of Ashkenazi Jewish backgroundin large population cohorts (Lek et al., 2016). The R1006K variant is a conservative amino acid substitution, which is not likely to impact secondary protein structure as these residues share similar properties. Furthermore, in-silico analyses, including protein predictors and evolutionaryconservation, support that this variant does not alter protein structure/function. Therefore, based on the currently available information, it is unclear whether this variant is a pathogenic variant or a rare benign variant.
