About PIGG

Cytogenetic location: 4p16.3 Genomic coordinates (GRCh38): 4:499,210-540,200 (from NCBI)

This gene has 26 transcripts (splice variants), 208 orthologues and is associated with 5 phenotypes. Ubiquitous expression in skin (RPKM 5.1), thyroid (RPKM 4.0) and 25 other tissues.

Summary

This gene encodes an enzyme involved in glycosylphosphatidylinositol-anchor biosynthesis. The encoded protein, which is localized to the endoplasmic reticulum, is involved in transferring ethanoloamine phosphate to mannose 2 of glycosylphosphatidylinositol species H7 to form species H8. Allelic variants of this gene have been associated with intellectual disability, hypotonia, and early-onset seizures. Alternative splicing results in multiple transcript variants.
