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.

Collection Method: clinical testing

The c.26G>A (p.C9Y) alteration is located in exon 2 (coding exon 1) of the IL1R1 gene. This alteration results from a G to A substitution at nucleotide position 26, causing the cysteine (C) at amino acid position 9 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
