PIGH

This gene encodes an endoplasmic reticulum associated protein that is involved in glycosylphosphatidylinositol (GPI)-anchor biosynthesis. The GPI anchor is a glycolipid found on many blood cells and which serves to anchor proteins to the cell surface. The protein encoded by this gene is a subunit of the GPI N-acetylglucosaminyl (GlcNAc) transferase that transfers GlcNAc to phosphatidylinositol (PI) on the cytoplasmic side of the endoplasmic reticulum.

Full Name

phosphatidylinositol glycan anchor biosynthesis, class H

Function

Part of the glycosylphosphatidylinositol-N-acetylglucosaminyltransferase (GPI-GnT) complex that catalyzes the transfer of N-acetylglucosamine from UDP-N-acetylglucosamine to phosphatidylinositol and participates in the first step of GPI biosynthesis.

Involvement in disease

Glycosylphosphatidylinositol biosynthesis defect 17 (GPIBD17):
An autosomal recessive disorder characterized by variable neurologic deficits that become apparent in infancy or early childhood. Clinical features include learning disabilities, mild-to-moderate developmental delay, seizures of variable severity, aggressive or over-friendly behavior, and autistic features.
