Genes affected

IFI27 (HGNC:5397): (interferon alpha inducible protein 27) Enables RNA polymerase II-specific DNA-binding transcription factor binding activity; identical protein binding activity; and lamin binding activity. Involved in several processes, including cellular protein metabolic process; defense response to other organism; and extrinsic apoptotic signaling pathway. Acts upstream of or within negative regulation of transcription by RNA polymerase II and regulation of protein export from nucleus. Located in mitochondrial membrane and nuclear inner membrane.

Feb 17, 2022

The c.306C>G (p.F102L) alteration is located in exon 5 (coding exon 4) of the IFI27 gene. This alteration results from a C to G substitution at nucleotide position 306, causing the phenylalanine (F) at amino acid position 102 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
