Genes affected

IRF3 (HGNC:6118): (interferon regulatory factor 3) This gene encodes a member of the interferon regulatory transcription factor (IRF) family. The encoded protein is found in an inactive cytoplasmic form that upon serine/threonine phosphorylation forms a complex with CREBBP. This complex translocates to the nucleus and activates the transcription of interferons alpha and beta, as well as other interferon-induced genes. The protein plays an important role in the innate immune response against DNA and RNA viruses. Mutations in this gene are associated with Encephalopathy, acute, infection-induced, herpes-specific, 7.

The c.1153C>G (p.P385A) alteration is located in exon 8 (coding exon 7) of the IRF3 gene. This alteration results from a C to G substitution at nucleotide position 1153, causing the proline (P) at amino acid position 385 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
