Definition:Recurrent gastrointestinal ulceration with dysfunctional platelets (GURDP) is an autosomal recessive disorder characterized by onset of severe gastrointestinal mucosal ulceration in early childhood. Affected individuals may have secondary iron deficiency anemia or malnourishment. Studies of platelet aggregation show a functional defect associated with decreased thromboxane-A2 production and decreased eicosanoid biosynthesis. The gastrointestinal disease is believed to result from decreased or absent production of prostaglandins that protect the gut mucosa. GURDP is caused by homozygous or compound heterozygous mutation in the PLA2G4A gene on chromosome 1q31. (OMIM)
