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.

ACMG classification

Verdict is Uncertain_significance. Variant got 0 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.07982013).

The c.623C>T (p.P208L) alteration is located in exon 5 (coding exon 4) of the IL1R1 gene. This alteration results from a C to T substitution at nucleotide position 623, causing the proline (P) at amino acid position 208 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
