Labcorp Genetics (formerly Invitae), Labcorp RCV001244977 SCV001418236 uncertain significance Congenital myasthenic syndrome 4A 2022-08-27 criteria provided, single submitter clinical testing This sequence change replaces asparagine, which is neutral and polar, with serine, which is neutral and polar, at codon 190 of the CHRNE protein (p.Asn190Ser). This variant is present in population databases (rs753756406, gnomAD 0.006%). This variant has not been reported in the literature in individuals affected with CHRNE-related conditions. ClinVar contains an entry for this variant (Variation ID: 969592). 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 CHRNE 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.
