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

The c.1546G>A (p.A516T) alteration is located in exon 9 (coding exon 9) of the IRF7 gene. This alteration results from a G to A substitution at nucleotide position 1546, causing the alanine (A) at amino acid position 516 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
