Genes affected
IRF7 (HGNC:6122): (interferon regulatory factor 7) This gene encodes interferon regulatory factor 7, a member of the interferon regulatory transcription factor (IRF) family. It has been shown to play a role in the transcriptional activation of virus-inducible cellular genes, including interferon beta chain genes. Inducible expression of IRF7 is largely restricted to lymphoid tissue. The encoded protein plays an important role in the innate immune response against DNA and RNA viruses.

This sequence change replaces glutamic acid, which is acidic and polar, with glutamine, which is neutral and polar, at codon 476 of the IRF7 protein (p.Glu476Gln). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with IRF7-related conditions. ClinVar contains an entry for this variant (Variation ID: 1023361). 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 IRF7 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. -
