IRAK3

Chr 12

interleukin 1 receptor associated kinase 3

Also known as: ASRT5, IRAKM

This gene encodes IRAK3, a putative inactive protein kinase that negatively regulates Toll-like receptor and IL-1 receptor signaling pathways in monocytes, macrophages, and dendritic cells by inhibiting IRAK1 and IRAK4 phosphorylation or stabilizing receptor complexes. Mutations are associated with asthma susceptibility and follow an autosomal dominant or complex inheritance pattern. The gene shows very low constraint against loss-of-function variants (pLI near zero, LOEUF 1.55), suggesting tolerance to such mutations.

The highest-scoring mechanism for this gene is gain-of-function.

Note: In-silico variant effect predictors (SIFT, PolyPhen, REVEL, CADD) may underestimate pathogenicity of missense variants in genes with GOF or DN mechanisms. Consider functional evidence and clinical context.
