Genes affected

IL1R1 (HGNC:5993): (interleukin 1 receptor type 1) This gene encodes a cytokine receptor that belongs to the interleukin-1 receptor family. The encoded protein is a receptor for interleukin-1 alpha, interleukin-1 beta, and interleukin-1 receptor antagonist. It is an important mediator involved in many cytokine-induced immune and inflammatory responses. This gene is located in a cluster of related cytokine receptor genes on chromosome 2q12.

IL1R1-AS1 (HGNC:53898): (IL1R1 antisense RNA 1)

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.87).
• BA1: GnomAd4 highest subpopulation (EAS) allele frequency at 95% confidence interval = 0.373 is higher than 0.05.
