Ribose-5-phosphate Isomerase - Rpi Deficiency

Rpi Deficiency

Ribose-5-phosphate isomerase deficiency is mutated in a rare disorder, Ribose-5-phosphate isomerase deficiency. The disease has only one known affected patient, diagnosed in 1999. It has been found to be caused by a combination of two mutations. The first is an insertion of a premature stop codon into the gene encoding the isomerase, and the second is a missense mutation. The molecular pathology is, as yet, unclear.
