not provided Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpDec 07, 2023This sequence change replaces glutamine, which is neutral and polar, with arginine, which is basic and polar, at codon 333 of the FAM46A protein (p.Gln333Arg). This variant is present in population databases (rs759391126, gnomAD 0.006%). This variant has not been reported in the literature in individuals affected with FAM46A-related conditions. ClinVar contains an entry for this variant (Variation ID: 1905224). 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 FAM46A 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. -
