Invitae RCV000815375 SCV000955825 uncertain significance Congenital myotonia, autosomal recessive form; Congenital myotonia, autosomal dominant form 2022-08-09 criteria provided, single submitter clinical testing This sequence change replaces glutamine, which is neutral and polar, with proline, which is neutral and non-polar, at codon 675 of the CLCN1 protein (p.Gln675Pro). This variant is present in population databases (rs768582911, gnomAD 0.02%). This variant has not been reported in the literature in individuals affected with CLCN1-related conditions. ClinVar contains an entry for this variant (Variation ID: 447059). 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 CLCN1 protein function. 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.
