Invitae | RCV001233409 | SCV001406002 | uncertain significance | Singleton-Merten syndrome 1; Aicardi-Goutieres syndrome 7 | 2023-11-28 | criteria provided, single submitter | clinical testing | This sequence change replaces valine, which is neutral and non-polar, with methionine, which is neutral and non-polar, at codon 973 of the IFIH1 protein (p.Val973Met). This variant is present in population databases (rs773526836, gnomAD 0.05%), and has an allele count higher than expected for a pathogenic variant. This variant has not been reported in the literature in individuals affected with IFIH1-related conditions. ClinVar contains an entry for this variant (Variation ID: 959969). 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. 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. |
