Labcorp Genetics (formerly Invitae), Labcorp RCV002018029 SCV002300582 uncertain significance Amyotrophic lateral sclerosis type 1; Perry syndrome; Neuronopathy, distal hereditary motor, type 7B 2021-08-02 criteria provided, single submitter clinical testing This variant has not been reported in the literature in individuals affected with DCTN1-related conditions. 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 tolerated. This variant is not present in population databases (ExAC no frequency). This sequence change replaces threonine with isoleucine at codon 125 of the DCTN1 protein (p.Thr125Ile). The threonine residue is weakly conserved and there is a moderate physicochemical difference between threonine and isoleucine.
