Also Known as GPI3; PNH1; PIG-A; MCAHS2; NEDEPH

Species: Homo sapiens

Gene Type: protein coding

Gene ID: 5277

About PIGA

Cytogenetic location: Xp22.2 Genomic coordinates (GRCh38): X:15,319,451-15,335,554 (from NCBI)

This gene has 19 transcripts (splice variants), 213 orthologues, 3 paralogues and is associated with 9 phenotypes. Ubiquitous expression in bone marrow (RPKM 9.8), urinary bladder (RPKM 3.0) and 24 other tissues.

Summary

This gene encodes a protein required for synthesis of N-acetylglucosaminyl phosphatidylinositol (GlcNAc-PI), the first intermediate in the biosynthetic pathway of GPI anchor. The GPI anchor is a glycolipid found on many blood cells and which serves to anchor proteins to the cell surface. Paroxysmal nocturnal hemoglobinuria, an acquired hematologic disorder, has been shown to result from mutations in this gene. Alternate splice variants have been characterized. A related pseudogene is located on chromosome 12. [provided by RefSeq, Jun 2010]
