Genes affected

NFKBIB (HGNC:7798): (NFKB inhibitor beta) The protein encoded by this gene belongs to the NF-kappa-B inhibitor family, which inhibit NF-kappa-B by complexing with, and trapping it in the cytoplasm. Phosphorylation of serine residues on these proteins by kinases marks them for destruction via the ubiquitination pathway, thereby allowing activation of the NF-kappa-B, which translocates to the nucleus to function as a transcription factor. Alternatively spliced transcript variants have been found for this gene.[provided by RefSeq, Jul 2011]

Jan 17, 2024

The c.637G>A (p.V213M) alteration is located in exon 4 (coding exon 4) of the NFKBIB gene. This alteration results from a G to A substitution at nucleotide position 637, causing the valine (V) at amino acid position 213 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
