Specifically the G149R, V362I, and R381Q IL23Rα chain variants are linked to protection against the development of Crohn disease and ulcerative colitis in humans.
We and others have shown that the minor, nonconserved allele Gln381 of the Arg381Gln single-nucleotide polymorphism (rs11209026G>A) of the IL-23 receptor gene (IL23R) protects against psoriasis.
Our results show that the R381Q IL23R variant leads to selective, potentially desirable, loss of function alterations in primary human CD4+ and CD8+ T cells, resulting in highly significant protection against autoimmunity.
This data provides an explanation for the protective role of R381Q in CD and may lead to the development of improved therapeutics for autoimmune disorders like CD.
