Primary immunodeficiency or monogenic inflammatory bowel disease v9.23 GPR15 Boaz Palterer gene: GPR15 was added
gene: GPR15 was added to Primary immunodeficiency or monogenic inflammatory bowel disease. Sources: Literature
Mode of inheritance for gene: GPR15 was set to BOTH monoallelic and biallelic (but BIALLELIC mutations cause a more SEVERE disease form), autosomal or pseudoautosomal
Publications for gene: GPR15 were set to 42259915
Phenotypes for gene: GPR15 were set to Inflammatory bowel disease; IBD; VEOIBD
Penetrance for gene: GPR15 were set to Incomplete
Review for gene: GPR15 was set to RED
Added comment: Cui et al. described multiple patients from multiple kindreds, harboring homozygous or compound heterozygous mutations in the GPR15 gene. They presented with severe early-onset inflammatory bowel disease. The underlying mechanism and phenotype were validated in vivo using complete Gpr15 knockout (KO) mouse models, demonstrating impaired colonic homing of regulatory CD8+ TIGR cells, an accumulation of inflammatory macrophages, and increased susceptibility to colitis.
