X-linked interleukin-1 receptor accessory protein-like 1, also known as IL-1R9, is a protein that in humans is encoded by the IL1RAPL1gene.[5][6][7] IL1RAPL1 is composed of 11 exons, about 1.37 Mb total.[8]
This gene and IL1RAPL2 are located at a region on chromosome X that is associated with X-linked non-syndromic mental retardation. Deletions and mutations in this gene were found in patients with mental retardation. This gene is expressed at a high level in post-natal brain structures involved in the hippocampal memory system, which suggests a specialized role in the physiological processes underlying memory and learning abilities.[7]
