Genes affected

NFKBIZ (HGNC:29805): (NFKB inhibitor zeta) This gene is a member of the ankyrin-repeat family and is induced by lipopolysaccharide (LPS). The C-terminal portion of the encoded product which contains the ankyrin repeats, shares high sequence similarity with the I kappa B family of proteins. The latter are known to play a role in inflammatory responses to LPS by their interaction with NF-B proteins through ankyrin-repeat domains. Studies in mouse indicate that this gene product is one of the nuclear I kappa B proteins and an activator of IL-6 production. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]

ACMG classification

Our verdict: Benign. The variant received -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.73).
• BS1: Variant frequency is greater than expected in population nfe. GnomAd4 allele frequency = 0.0196 (2955/150706) while in subpopulation NFE AF = 0.0259 (1755/67692). AF 95% confidence interval is 0.0249. There are 52 homozygotes in GnomAd4. There are 1547 alleles in the male GnomAd4 subpopulation. Median coverage is 31. This position passed quality control check.
• BS2: High Homozygotes in GnomAd4 at 52 Unknown gene
