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 (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 ACTC1-related conditions. ClinVar contains an entry for this variant (Variation ID: 264401). This variant is not present in population databases (ExAC no frequency). This sequence change replaces aspartic acid with glutamic acid at codon 159 of the ACTC1 protein (p.Asp159Glu). The aspartic acid residue is highly conserved and there is a small physicochemical difference between aspartic acid and glutamic acid.
