GeneDx RCV000658404 SCV000780176 uncertain significance not provided 2018-05-25 criteria provided, single submitter clinical testing A variant of uncertain significance has been identified in the CHRNA2 gene. The V352A variant has not been published as a pathogenic variant, nor has it been reported as a benign variant to our knowledge. The V352A variant is not observed in large population cohorts (Lek et al., 2016). In-silico analyses, including protein predictors and evolutionary conservation, support a deleterious effect. However, the V352A variant is a conservative amino acid substitution, which is not likely to impact secondary protein structure as these residues share similar properties. Based on the currently available information, it is unclear whether this variant is a pathogenic variant or a rare benign variant.
