Variants pathogenicity by type

Statistics on ClinVar variants can assist in determining whether a specific variant type in the IL18R1 gene is commonly pathogenic or not.

In the table, we include only reliable ClinVar variants with their consequences to MANE Select, Mane Plus Clinical transcripts, or transcripts with TSL equals 1. Click the count to view the source variants.

Warning: slight differences between displayed counts and the number of variants in ClinVar may occur, primarily due to (1) the application of a different transcript and/or consequence by our variant effect predictor or (2) differences in clinical significance: we classify Benign/Likely benign variants as Likely benign and Pathogenic/Likely pathogenic variants as Likely pathogenic.

• Function: FUNCTION: Within the IL18 receptor complex, responsible for the binding of the proinflammatory cytokine IL18, but not IL1A nor IL1B (PubMed:8626725, PubMed:14528293, PubMed:25261253, PubMed:25500532). Involved in IL18-mediated IFNG synthesis from T- helper 1 (Th1) cells (PubMed:10653850). Contributes to IL18- induced cytokine production, either independently of SLC12A3, or as a complex with SLC12A3 (By similarity). {ECO:0000250|UniProtKB:Q61098, ECO:0000269|PubMed:10653850, ECO:0000269|PubMed:14528293, ECO:0000269|PubMed:25261253, ECO:0000269|PubMed:25500532, ECO:0000269|PubMed:8626725}.
