Uncertain significance, criteria provided, single submitterclinical testingGeneDxJan 24, 2017The V71L variant has been previously reported as a benign polymorphism which showed stable expression of the protein similar to wild type expression (Valente et al., 2010). This variant is observed in 70/9798 (0.7%) alleles from individuals of African background (Lek et al., 2016; 1000 Genomes Consortium et al., 2015; Exome Variant Server). The V71L 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 where amino acids with similar properties to Valine are tolerated across species. However, in silico analysis is inconsistent in its predictions as to whether or not the variant is damaging to the protein structure/function. Additionally, missense variants in a nearby residue (R73C/H/L) have been reported in Human Gene Mutation Database in association with Joubert syndrome (Stenson et al., 2014). Based on the currently available information, it is unclear whether the V71L variant is a pathogenic variant or a rare benign variant. -
