Genes affected

RIGI (HGNC:19102): (RNA sensor RIG-I) DEAD box proteins, characterized by the conserved motif Asp-Glu-Ala-Asp (DEAD), are putative RNA helicases which are implicated in a number of cellular processes involving RNA binding and alteration of RNA secondary structure. This gene encodes a protein containing RNA helicase-DEAD box protein motifs and a caspase recruitment domain (CARD). It is involved in viral double-stranded (ds) RNA recognition and the regulation of the antiviral innate immune response. Mutations in this gene are associated with Singleton-Merten syndrome 2.

This sequence change replaces isoleucine, which is neutral and non-polar, with threonine, which is neutral and polar, at codon 406 of the DDX58 protein (p.Ile406Thr). This variant is present in population databases (rs951618, gnomAD 0.009%). This variant has not been reported in the literature in individuals affected with DDX58-related conditions. ClinVar contains an entry for this variant (Variation ID: 1496911). 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 expected to disrupt DDX58 protein function with a positive predictive value of 80%. Experimental studies have shown that this missense change does not substantially affect DDX58 function (PMID: 19859543, 25620203). 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. -
