Labcorp Genetics (formerly Invitae), Labcorp RCV001224259 SCV001396446 uncertain significance Amyotrophic lateral sclerosis type 1; Perry syndrome; Neuronopathy, distal hereditary motor, type 7B 2023-12-09 criteria provided, single submitter clinical testing This sequence change replaces phenylalanine, which is neutral and non-polar, with leucine, which is neutral and non-polar, at codon 701 of the DCTN1 protein (p.Phe701Leu). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with DCTN1-related conditions. ClinVar contains an entry for this variant (Variation ID: 952198). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt DCTN1 protein function with a negative predictive value of 80%. 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.
