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. This variant has not been reported in the literature in individuals affected with DCTN1-related conditions. This variant is not present in population databases (ExAC no frequency). This sequence change replaces isoleucine with serine at codon 341 of the DCTN1 protein (p.Ile341Ser). The isoleucine residue is highly conserved and there is a large physicochemical difference between isoleucine and serine.
