Therefore, it has been classified as a Variant of Uncertain Significance. A different missense substitution at this codon (p.Met425Val) has been reported in an individual affected with a TGFBR2-related disease (PMID: 16251899). 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 disruptive, 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 TGFBR2-related disease. This variant is not present in population databases (ExAC no frequency). This sequence change replaces methionine with threonine at codon 425 of the TGFBR2 protein (p.Met425Thr). The methionine residue is highly conserved and there is a moderate physicochemical difference between methionine and threonine. |
