GeneDx RCV000412831 SCV000492204 uncertain significance not specified 2016-11-29 criteria provided, single submitter clinical testing A variant of uncertain significance has been identified in the NOTCH1 gene. The I1445M variant has not beenpublished as a pathogenic variant, nor has it been reported as a benign variant to our knowledge. It was not observedin approximately 6,200 individuals of European and African American ancestry in the NHLBI Exome SequencingProject, indicating it is not a common benign variant in these populations. The I1445M variant is a conservativeamino acid substitution, which is not likely to impact secondary protein structure as these residues share similarproperties. In addition, this substitution occurs at a position where amino acids with similar properties to isoleucine(I) are tolerated across species. Nonetheless, methionine (M) is not wild type in any species, and in silico analysis isinconsistent in its predictions as to whether or not this variant is damaging to the protein structure/function.Therefore, based on the currently available information, it is unclear whether this variant is pathogenic or rare benign.This result cannot be interpreted for diagnosis or used for family member screening at this time.
