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.

Ambry Genetics

Dec 07, 2021

The c.887G>T (p.R296L) alteration is located in exon 4 (coding exon 4) of the NFKBIL1 gene. This alteration results from a G to T substitution at nucleotide position 887, causing the arginine (R) at amino acid position 296 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
