IL1RAPL2, IL1R9, X-linked interleukin-1 receptor accessory protein-like 2, IL1RAPL-2-related protein, Interleukin-1 receptor 9, Three immunoglobulin domain-containing IL-1 receptor-related 1

The protein encoded by this gene is a member of the interleukin 1 receptor family. This protein is similar to the interleukin 1 accessory proteins, and is most closely related to interleukin 1 receptor accessory protein-like 1 (IL1RAPL1). This gene and IL1RAPL1 are located at a region on chromosome X that is associated with X-linked non-syndromic mental retardation.
