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]

The c.163A>G (p.K55E) alteration is located in exon 2 (coding exon 1) of the IFI16 gene. This alteration results from a A to G substitution at nucleotide position 163, causing the lysine (K) at amino acid position 55 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
