A variant of uncertain significance has been identified in the PLEKHG5 gene. The R956K variant has not been published as a pathogenic variant, nor has it been reported as a benign variant to our knowledge. The R956K variant is not observed at a significant frequency in large population cohorts (Lek et al., 2016; 1000 Genomes Consortium et al., 2015; Exome Variant Server). The R956K variant is a conservative amino acid substitution, which is not likely to impact secondary protein structure as these residues share similar propertiess. This substitution occurs at a position that is not conserved, and in silico analysis predicts this variant likely does not alter 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.
