Genes affected

NFKB2 (HGNC:7795): (nuclear factor kappa B subunit 2) This gene encodes a subunit of the transcription factor complex nuclear factor-kappa-B (NFkB). The NFkB complex is expressed in numerous cell types and functions as a central activator of genes involved in inflammation and immune function. The protein encoded by this gene can function as both a transcriptional activator or repressor depending on its dimerization partner. The p100 full-length protein is co-translationally processed into a p52 active form. Chromosomal rearrangements and translocations of this locus have been observed in B cell lymphomas, some of which may result in the formation of fusion proteins. There is a pseudogene for this gene on chromosome 18. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Dec 2013]

PM2

Very rare variant in population databases, with high coverage;

PP2

Missense variant in gene, where missense usually causes diseases (based on misZ statistic), NFKB2. . Gene score misZ 3.9376 (greater than the threshold 3.09). Trascript score misZ 3.5752 (greater than threshold 3.09). GenCC has associacion of gene with common variable immunodeficiency, deficiency in anterior pituitary function - variable immunodeficiency syndrome, immunodeficiency, common variable, 10.

BP4

Computational evidence support a benign effect (MetaRNN=0.12578145).

BS1

Variant frequency is greater than expected in population amr. gnomad4 allele frequency = 0.0000197 (3/152098) while in subpopulation AMR AF= 0.000196 (3/15272). AF 95% confidence interval is 0.0000529. There are 0 homozygotes in gnomad4. There are 2 alleles in male gnomad4 subpopulation. Median coverage is 31. This position pass quality control queck.

This sequence change replaces glycine, which is neutral and non-polar, with arginine, which is basic and polar, at codon 8 of the NFKB2 protein (p.Gly8Arg). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with NFKB2-related conditions. ClinVar contains an entry for this variant (Variation ID: 1517693). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant¬†is likely to be tolerated. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
