Genes affected

NFKBIE (HGNC:7799): (NFKB inhibitor epsilon) The protein encoded by this gene binds to components of NF-kappa-B, trapping the complex in the cytoplasm and preventing it from activating genes in the nucleus. Phosphorylation of the encoded protein targets it for destruction by the ubiquitin pathway, which activates NF-kappa-B by making it available to translocate to the nucleus.

The c.1004G>A (p.C335Y) alteration is located in exon 3 (coding exon 3) of the NFKBIE gene. This alteration results from a G to A substitution at nucleotide position 1004, causing the cysteine (C) at amino acid position 335 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
