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.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 13, 2024The c.746G>A (p.R249Q) alteration is located in exon 4 (coding exon 4) of the NFKBIL1 gene. This alteration results from a G to A substitution at nucleotide position 746, causing the arginine (R) at amino acid position 249 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
