Genes affected
NFKB1 (HGNC:7794): (nuclear factor kappa B subunit 1) This gene encodes a 105 kD protein which can undergo cotranslational processing by the 26S proteasome to produce a 50 kD protein. The 105 kD protein is a Rel protein-specific transcription inhibitor and the 50 kD protein is a DNA binding subunit of the NF-kappa-B (NFKB) protein complex. NFKB is a transcription regulator that is activated by various intra- and extra-cellular stimuli such as cytokines, oxidant-free radicals, ultraviolet irradiation, and bacterial or viral products. Activated NFKB translocates into the nucleus and stimulates the expression of genes involved in a wide variety of biological functions. Inappropriate activation of NFKB has been associated with a number of inflammatory diseases while persistent inhibition of NFKB leads to inappropriate immune cell development or delayed cell growth. NFKB is a critical regulator of the immediate-early response to viral infection. Alternative splicing results in multiple transcript variants encoding different isoforms, at least one of which is proteolytically processed. [provided by RefSeq, Aug 2020]

ACMG classification

Classification made for transcript

Verdict is Benign. Variant got -19 ACMG points.

PP2
Missense variant in gene, where missense usually causes diseases (based on misZ statistic), NFKB1. . Gene score misZ 3.1933 (greater than the threshold 3.09). Trascript score misZ 3.9653 (greater than threshold 3.09). GenCC has associacion of gene with immunodeficiency, common variable, 12, common variable immunodeficiency.
BP4
Computational evidence support a benign effect (MetaRNN=0.0024580657).
BP6
Variant 4-102597543-A-G is Benign according to our data. Variant chr4-102597543-A-G is described in ClinVar as [Likely_benign]. Clinvar id is 445400.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
BS1
Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.0176 (2681/152342) while in subpopulation AFR AF= 0.0444 (1845/41578). AF 95% confidence interval is 0.0427.
