Therefore, it has been classified as a Variant of Uncertain Significance. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site, but this prediction has not been confirmed by published transcriptional studies. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated, but these predictions have not been confirmed by published functional studies and their clinical significance is uncertain. This variant has not been reported in the literature in individuals with TSC1-related conditions. This variant is present in population databases (rs757025842, ExAC 0.001%). This sequence change replaces lysine with arginine at codon 918 of the TSC1 protein (p.Lys918Arg). The lysine residue is moderately conserved and there is a small physicochemical difference between lysine and arginine. |
