Description

This variant is not present in population databases (ExAC no frequency). 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. 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"). This variant has not been reported in the literature in individuals with GAA-related conditions. This sequence change replaces proline with threonine at codon 39 of the GAA protein (p.Pro39Thr). The proline residue is moderately conserved and there is a small physicochemical difference between proline and threonine.
