Labcorp Genetics (formerly Invitae), Labcorp RCV001877017 SCV002128361 uncertain significance Congenital myotonia, autosomal recessive form; Congenital myotonia, autosomal dominant form 2021-08-05 criteria provided, single submitter clinical testing 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. 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. This variant has not been reported in the literature in individuals affected with CLCN1-related conditions. This variant is not present in population databases (ExAC no frequency). This sequence change replaces valine with glutamic acid at codon 122 of the CLCN1 protein (p.Val122Glu). The valine residue is moderately conserved and there is a moderate physicochemical difference between valine and glutamic acid.
