Invitae RCV001232506 SCV001405068 uncertain significance Tuberous sclerosis 1 2020-07-12 criteria provided, single submitter clinical testing This sequence change replaces histidine with arginine at codon 206 of the TSC1 protein (p.His206Arg). The histidine residue is highly conserved and there is a small physicochemical difference between histidine and arginine. This variant is not present in population databases (ExAC no frequency). This variant has not been reported in the literature in individuals with TSC1-related conditions. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Tolerated"; PolyPhen-2: "Possibly Damaging"; Align-GVGD: "Class C0"). In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance.
