Genes affected

SCNN1G (HGNC:10602): (sodium channel epithelial 1 subunit gamma) Nonvoltage-gated, amiloride-sensitive, sodium channels control fluid and electrolyte transport across epithelia in many organs. These channels are heteromeric complexes consisting of 3 subunits: alpha, beta, and gamma. This gene encodes the gamma subunit, and mutations in this gene have been associated with Liddle syndrome.

Collection Method:clinical testing

This sequence change replaces methionine, which is neutral and non-polar, with lysine, which is basic and polar, at codon 517 of the SCNN1G protein (p.Met517Lys). This variant is present in population databases (rs144653364, gnomAD 0.2%). This variant has not been reported in the literature in individuals affected with SCNN1G-related conditions. ClinVar contains an entry for this variant (Variation ID: 2883968). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) indicates that this missense variant is not expected to disrupt SCNN1G protein function with a negative predictive value of 80%. 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. -
