Description
A variant of uncertain significance has been identified in the BICD2 gene. The G514S variant has been reported as a possible pathogenic variant in an individual with peripheral neuropathy; however no additional information was provided (Laššuthová et al.,2016). The G514S variant is observed in 5/16502 (0.03%) alleles from individuals of South Asian background, (Lek et al., 2016; 1000 Genomes Consortium et al., 2015; Exome Variant Server). The G514S 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 that is conserved 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. Therefore, based on the currently available information, it is unclear whether this variant is a pathogenic variant or a rare benign variant.
