Genes affected

NFKBID (HGNC:15671): (NFKB inhibitor delta) Predicted to enable NF-kappaB binding activity. Predicted to be involved in T cell receptor signaling pathway; positive regulation of T-helper 17 cell differentiation; and regulation of gene expression. Predicted to act upstream of or within several processes, including negative regulation of NF-kappaB transcription factor activity; negative regulation of T cell differentiation in thymus; and positive regulation of thymocyte apoptotic process. Predicted to be active in nucleus. [provided by Alliance of Genome Resources, Apr 2022]

Collection Method: clinical testing

The c.227G>A (p.R76Q) alteration is located in exon 6 (coding exon 3) of the NFKBID gene. This alteration results from a G to A substitution at nucleotide position 227, causing the arginine (R) at amino acid position 76 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
