Disease

PNPH_HUMAN Defects in PNP are the cause of purine nucleoside phosphorylase deficiency (PNPD) [MIM:613179. It leads to a severe T-cell immunodeficiency with neurologic disorder in children.^[1] ^[2] ^[3]

Function

PNPH_HUMAN The purine nucleoside phosphorylases catalyze the phosphorolytic breakdown of the N-glycosidic bond in the beta-(deoxy)ribonucleoside molecules, with the formation of the corresponding free purine bases and pentose-1-phosphate.^[4]
