Genes affected

IL1RAP (HGNC:5995): (interleukin 1 receptor accessory protein) This gene encodes a component of the interleukin 1 receptor complex, which initiates signalling events that result in the activation of interleukin 1-responsive genes. Alternative splicing of this gene results in membrane-bound and soluble isoforms differing in their C-terminus. The ratio of soluble to membrane-bound forms increases during acute-phase induction or stress. [provided by RefSeq, Jul 2018]

ACMG classification

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

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.79).
• BA1: GnomAd4 highest subpopulation (EAS) allele frequency at 95% confidence interval = 0.409 is higher than 0.05.
