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.

Collection Method: 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. This variant has not been reported in the literature in individuals affected with IRF7-related conditions. This variant is present in population databases (rs772699762, gnomAD 0.02%). This sequence change disrupts the translational stop signal of the IRF7 mRNA. It is expected to extend the length of the IRF7 protein by 0 additional amino acid residues. -
