GeneDx RCV000428564 SCV000536358 uncertain significance not provided 2017-01-20 criteria provided, single submitter clinical testing A variant of uncertain significance has been identified in the ARFGEF2 gene. The N430S variant has not been published as a pathogenic variant, nor has it been reported as a benign variant to our knowledge. The N430S 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 N430S 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 Asparagine are tolerated across species. In silico analysis is inconsistent in its predictions as to whether or not the variant is damaging to the protein structure/function. Based on the currently available information, it is unclear whether this variant is a pathogenic variant or a rare benign variant.
