The threonine residue is highly conserved and there is a moderate physicochemical difference between threonine and isoleucine. This sequence change has not been published in the literature and is present in population databases (0.015%, Exome Aggregation Consortium, URL:, [11, 2014]). Algorithms developed to predict the effect of missense changes on protein structure and function do not agree on the potential impact of this missense change (SIFT: "deleterious"; PolyPhen-2: "probably damaging”; Align-GVGD: "Class C0"). In summary, this is a rare missense change with uncertain impact on protein function. Although there is no indication that this sequence change causes disease, the evidence is insufficient at this time to prove that conclusively. Therefore, it has been classified as a Variant of Uncertain Significance.
