Genes affected

IFI6 (HGNC:4054): (interferon alpha inducible protein 6) This gene was first identified as one of the many genes induced by interferon. The encoded protein may play a critical role in the regulation of apoptosis. A minisatellite that consists of 26 repeats of a 12 nucleotide repeating element resembling the mammalian splice donor consensus sequence begins near the end of the second exon. Alternatively spliced transcript variants that encode different isoforms by using the two downstream repeat units as splice donor sites have been described. [provided by RefSeq, Jul 2008]

Mar 24, 2023

The c.356T>C (p.I119T) alteration is located in exon 5 (coding exon 4) of the IFI6 gene. This alteration results from a T to C substitution at nucleotide position 356, causing the isoleucine (I) at amino acid position 119 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
