Labcorp Genetics (formerly Invitae), Labcorp RCV000644481 SCV000766179 uncertain significance Amyotrophic lateral sclerosis type 1; Perry syndrome; Neuronopathy, distal hereditary motor, type 7B 2022-09-04 criteria provided, single submitter clinical testing ClinVar contains an entry for this variant (Variation ID: 536162). This variant has not been reported in the literature in individuals affected with DCTN1-related conditions. This variant is present in population databases (rs150746209, gnomAD 0.002%). This sequence change replaces arginine, which is basic and polar, with cysteine, which is neutral and slightly polar, at codon 669 of the DCTN1 protein (p.Arg669Cys). 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. 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.
