Labcorp Genetics (formerly Invitae), Labcorp RCV002024175 SCV002316914 uncertain significance Congenital myotonia, autosomal recessive form; Congenital myotonia, autosomal dominant form 2022-06-28 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 expected to disrupt CLCN1 protein function. This variant has not been reported in the literature in individuals affected with CLCN1-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change replaces valine, which is neutral and non-polar, with glycine, which is neutral and non-polar, at codon 131 of the CLCN1 protein (p.Val131Gly).
