Pnp Gene plays an important role in the study of neurodegenerative diseases. This page provides comprehensive information about this topic, including its mechanisms, significance in disease processes, and therapeutic implications.

Introduction

Pnp Gene is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes. [@additional]

The PNP (Purine Nucleoside Phosphorylase) gene encodes an enzyme involved in purine metabolism that catalyzes the phosphorolysis of purine nucleosides. PNP deficiency causes a severe immunodeficiency disorder and neurological symptoms. Located at 14q11.2, PNP has also been implicated in autoimmune encephalitis and cancer immunotherapy. [@ncbi]
