PNPO - pyridoxamine 5'-phosphate oxidase Gene

Also Known as PDXPO; HEL-S-302

Species: Homo sapiens

Gene Type: protein coding

Gene ID: 55163

About PNPO

Cytogenetic location: 17q21.32 Genomic coordinates (GRCh38): 17:47,941,571-47,949,308 (from NCBI)

This gene has 17 transcripts (splice variants), 200 orthologues and is associated with 3 phenotypes. Ubiquitous expression in liver (RPKM 22.0), kidney (RPKM 16.0) and 23 other tissues.

Summary

The enzyme encoded by this gene catalyzes the terminal, rate-limiting step in the synthesis of pyridoxal 5'-phosphate, also known as vitamin B6. Vitamin B6 is a required co-factor for Enzymes involved in both homocysteine metabolism and synthesis of neurotransmitters such as Catecholamine. Mutations in this gene result in pyridoxamine 5'-phosphate oxidase (PNPO) deficiency, a form of neonatal epileptic encephalopathy. [provided by RefSeq, Oct 2008]
