Labcorp Genetics (formerly Invitae), Labcorp RCV002042527 SCV002294535 uncertain significance Singleton-Merten syndrome 1; Aicardi-Goutieres syndrome 7 2022-11-03 criteria provided, single submitter clinical testing 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. 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) has been performed at Invitae for this missense variant, however the output from this modeling did not meet the statistical confidence thresholds required to predict the impact of this variant on IFIH1 protein function. ClinVar contains an entry for this variant (Variation ID: 1500204). This variant has not been reported in the literature in individuals affected with IFIH1-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change replaces serine, which is neutral and polar, with proline, which is neutral and non-polar, at codon 399 of the IFIH1 protein (p.Ser399Pro).
