Summaries for PNP Gene

Entrez Gene Summary for PNP Gene

  • This gene encodes an enzyme which reversibly catalyzes the phosphorolysis of purine nucleosides. The enzyme is trimeric, containing three identical subunits. Mutations which result in nucleoside phosphorylase deficiency result in defective T-cell (cell-mediated) immunity but can also affect B-cell immunity and antibody responses. Neurologic disorders may also be apparent in patients with immune defects. A known polymorphism at aa position 51 that does not affect enzyme activity has been described. A pseudogene has been identified on chromosome 2. [provided by RefSeq, Jul 2008]

GeneCards Summary for PNP Gene

PNP (Purine Nucleoside Phosphorylase) is a Protein Coding gene. Diseases associated with PNP include immunodeficiency due to purine nucleoside phosphorylase deficiency and pedophilia. Among its related pathways are Metabolism and Metabolism. GO annotations related to this gene include drug binding and nucleoside binding.

UniProtKB/Swiss-Prot for PNP Gene

  • 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.

Disorders for PNP Gene

(1) OMIM Diseases for PNP Gene (164050)


  • Purine nucleoside phosphorylase deficiency (PNPD) [MIM:613179]: A disorder that interrupts both the catabolism of inosine into hypoxanthine and guanosine into guanine, and leads to the accumulation of guanosine, inosine, and their deoxified by-products. The main clinical presentation is recurrent infections due to severe T-cell immunodeficiency. Some patients also have neurologic impairment. {ECO:0000269 PubMed:1384322, ECO:0000269 PubMed:3029074, ECO:0000269 PubMed:8931706}. Note=The disease is caused by mutations affecting the gene represented in this entry.
