RESUMO
IL1RAPL1 gene is one of the genes related to X-linked nonspecific mental retardation(MRX), but its pathogenic mechanism has not been fully clarified.Interleukin-1 receptor accessory protein like 1(IL1RAPL1) is a synaptic adhesion molecule located on postsynaptic membrane.The mutation of IL1RAPL1 gene can lead to the deletion or dysfunction of this protein.Recent studies have shown that the IL1RAPL1 protein regulates dendritic formation and mediates the activity of IL-1β molecules on dendritic morphology.This review describes the latest advances in synaptic and neuronal functions of IL1RAPL1, and summarizes some gene mutations that have been found to be associated with mental retardation(MR)and autism spectrum disorder(ASD), to provide evidence for clinical diagnosis and treatment.
