Genes affected

CHUK (HGNC:1974): (component of inhibitor of nuclear factor kappa B kinase complex) This gene encodes a member of the serine/threonine protein kinase family. The encoded protein, a component of a cytokine-activated protein complex that is an inhibitor of the essential transcription factor NF-kappa-B complex, phosphorylates sites that trigger the degradation of the inhibitor via the ubiquination pathway, thereby activating the transcription factor.

ACMG classification

Verdict is Benign. Variant got -20 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=6.5614154E-6).
• BP6: Variant 10-100218126-C-T is Benign according to our data. Variant chr10-100218126-C-T is described in ClinVar as [Benign]. Clinvar id is 1221248.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars. Variant chr10-100218126-C-T is described in Lovd as [Benign].
• BA1: GnomAd4 highest subpopulation (AFR) allele frequency at 95% confidence interval = 0.743 is higher than 0.05.
