Labcorp Genetics (formerly Invitae), Labcorp RCV002632385 SCV003501677 uncertain significance Nemaline myopathy 8 2023-07-10 criteria provided, single submitter clinical testing 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. 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 KLHL40 protein function. This sequence change replaces valine, which is neutral and non-polar, with alanine, which is neutral and non-polar, at codon 576 of the KLHL40 protein (p.Val576Ala). This variant is present in population databases (no rsID available, gnomAD 0.0009%). This variant has not been reported in the literature in individuals affected with KLHL40-related conditions. ClinVar contains an entry for this variant (Variation ID: 2185026).
