GeneDx RCV000490041 SCV000577345 uncertain significance not provided 2017-04-03 criteria provided, single submitter clinical testing A variant of uncertain significance has been identified in the KCNT1 gene. The M1157I variant has not been published as a pathogenic variant, nor has it been reported as a benign variant to our knowledge. The M1157I variant is not observed in large population cohorts (Lek et al., 2016; 1000 Genomes Consortium et al., 2015; Exome Variant Server). This substitution occurs at a position that is conserved across species. In silico analysis predicts this variant is probably damaging to the protein structure/function. However, the M1157I variant is a conservative amino acid substitution, which is not likely to impact secondary protein structure as these residues share similar properties. Therefore, based on the currently available information, it is unclear whether this variant is a pathogenic variant or a rare benign variant.
