Genes affected

NFKBIL1 (HGNC:7800): (NFKB inhibitor like 1) This gene encodes a divergent member of the I-kappa-B family of proteins. Its function has not been determined. The gene lies within the major histocompatibility complex (MHC) class I region on chromosome 6. Multiple transcript variants encoding different isoforms have been found for this gene.

The c.797A>G (p.Q266R) alteration is located in exon 4 (coding exon 4) of the NFKBIL1 gene. This alteration results from a A to G substitution at nucleotide position 797, causing the glutamine (Q) at amino acid position 266 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
