== Disease ==
[[http://www.uniprot.org/uniprot/PNPH_HUMAN PNPH_HUMAN]] Defects in PNP are the cause of purine nucleoside phosphorylase deficiency (PNPD) [MIM:[http://omim.org/entry/613179 613179]]. It leads to a severe T-cell immunodeficiency with neurologic disorder in children.<ref>PMID:3029074</ref> <ref>PMID:1384322</ref> <ref>PMID:8931706</ref>  
== Function ==
[[http://www.uniprot.org/uniprot/PNPH_HUMAN 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.<ref>PMID:2104852</ref>
