Genes affected

IFI16 (HGNC:5395): (interferon gamma inducible protein 16) This gene encodes a member of the HIN-200 (hematopoietic interferon-inducible nuclear antigens with 200 amino acid repeats) family of cytokines. The encoded protein contains domains involved in DNA binding, transcriptional regulation, and protein-protein interactions. The protein localizes to the nucleoplasm and nucleoli, and interacts with p53 and retinoblastoma-1. It modulates p53 function, and inhibits cell growth in the Ras/Raf signaling pathway. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Apr 2011]

Ambry Genetics

Dec 15, 2023

The c.990G>T (p.K330N) alteration is located in exon 6 (coding exon 5) of the IFI16 gene. This alteration results from a G to T substitution at nucleotide position 990, causing the lysine (K) at amino acid position 330 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
