Invitae RCV000206823 SCV000260997 uncertain significance Lynch syndrome 2015-10-02 criteria provided, single submitter clinical testing This sequence change replaces alanine with proline at codon 580 of the MLH1 protein (p.Ala580Pro). The alanine residue is highly conserved and there is a small physicochemical difference between alanine and proline. This variant is not present in population databases (ExAC no frequency) and has not been reported in the literature. 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: "Benign"; Align-GVGD: "Class C25"). In summary, this is a novel missense change with uncertain impact on protein function. It has been classified as a Variant of Uncertain Significance.
