Variant rs201869683 details in Genebe, Genetics Data Aggregator

Variant summary

Our verdict is Uncertain significance. Variant got 1 ACMG points: 3P and 2B. PM2PP2BP4_Moderate

The ENST00000520810.6(IKBKB):c.2228A>G(p.Gln743Arg) variant causes a missense change. The variant allele was found at a frequency of 0.000000684 in 1,461,880 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 15/21 in silico tools predict a benign outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. Q743L) has been classified as Uncertain significance.

Genes affected

IKBKB (HGNC:5960): (inhibitor of nuclear factor kappa B kinase subunit beta) The protein encoded by this gene phosphorylates the inhibitor in the inhibitor/NF-kappa-B complex, causing dissociation of the inhibitor and activation of NF-kappa-B. The encoded protein itself is found in a complex of proteins. Several transcript variants, some protein-coding and some not, have been found for this gene. [provided by RefSeq, Sep 2011]

ACMG classification

Classification made for transcript

Verdict is Uncertain_significance. Variant got 1 ACMG points.

PM2

Very rare variant in population databases, with high coverage;

PP2

Missense variant in gene, where missense usually causes diseases (based on misZ statistic), IKBKB. . Gene score misZ 2.5876 (greater than the threshold 3.09). Trascript score misZ 3.3125 (greater than threshold 3.09). GenCC has associacion of gene with immunodeficiency 15a, severe combined immunodeficiency due to IKK2 deficiency.

BP4

Computational evidence support a benign effect (MetaRNN=0.10410881).
