Description

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: "Deleterious"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C15"). This variant has not been reported in the literature in individuals with ACTN2-related conditions. This variant is not present in population databases (ExAC no frequency). This sequence change replaces phenylalanine with leucine at codon 884 of the ACTN2 protein (p.Phe884Leu). The phenylalanine residue is highly conserved and there is a small physicochemical difference between phenylalanine and leucine.
