GeneDx RCV000478183 SCV000573702 uncertain significance not provided 2017-03-07 criteria provided, single submitter clinical testing A variant of uncertain significance has been identified in the NRXN1 gene. The P108A variant has not been published as a pathogenic variant, nor has it been reported as a benign variant to our knowledge. The P108A 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 P108A variant is a semi-conservative amino acid substitution, which may impact secondary protein structure as these residues differ in some properties. This substitution occurs at a position that is conserved in mammals; however, Alanine is observed at this position in evolution. 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.
