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

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.92).
• BS1: Variant frequency is greater than expected in population nfe. gnomad4 allele frequency = 0.022 (3351/152156) while in subpopulation NFE AF= 0.0336 (2288/67998). AF 95% confidence interval is 0.0325. There are 70 homozygotes in gnomad4. There are 1631 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.
• BS2: High Homozygotes in GnomAd4 at 70 AR gene
