Genes affected

IRF1 (HGNC:6116): (interferon regulatory factor 1) The protein encoded by this gene is a transcriptional regulator and tumor suppressor, serving as an activator of genes involved in both innate and acquired immune responses. The encoded protein activates the transcription of genes involved in the body's response to viruses and bacteria, playing a role in cell proliferation, apoptosis, the immune response, and DNA damage response. This protein represses the transcription of several other genes. As a tumor suppressor, it both suppresses tumor cell growth and stimulates an immune response against tumor cells. Defects in this gene have been associated with gastric cancer, myelogenous leukemia, and lung cancer. [provided by RefSeq, Aug 2017]

Ambry Genetics

May 26, 2022

The c.357G>C (p.Q119H) alteration is located in exon 4 (coding exon 3) of the IRF1 gene. This alteration results from a G to C substitution at nucleotide position 357, causing the glutamine (Q) at amino acid position 119 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
