Mice homozygous for null mutations display prenatal, neonatal or postnatal lethality. For some alleles lethality is associated with vascular abnormalities. Temporally restricted overexpression in intestinal epithelium leads to increased susceptibility to DSS-induced colitis morbidity. Homozygosity for the disease-related p.A529V mutation affects blood cell development and leads to polycythemia.
