Description

The I637V variant has not been published as a pathogenic variant, nor has it been reported as a benign variant to our knowledge. The I637V variant is observed in 37/16512 (0.22%) alleles from individuals of South Asian background, including 1 homozygous individual in large population cohorts (Lek et al., 2016; 1000 Genomes Consortium et al., 2015; Exome Variant Server). This 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 Isoleucine 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.
