General annotation (Comments)

Function	Ethanolamine phosphate transferase involved in glycosylphosphatidylinositol-anchor biosynthesis. Transfers ethanolamine phosphate to the first alpha-1,4-linked mannose of the glycosylphosphatidylinositol precursor of GPI-anchor By similarity. May act as suppressor of replication stress and chromosome missegregation. Ref.4
Pathway	Glycolipid biosynthesis; glycosylphosphatidylinositol-anchor biosynthesis.
Subcellular location	Endoplasmic reticulum membrane; Multi-pass membrane protein By similarity.
Involvement in disease	Multiple congenital anomalies-hypotonia-seizures syndrome 1 (MCAHS1) [MIM:614080]: An autosomal recessive disorder characterized by neonatal hypotonia, lack of psychomotor development, seizures, dysmorphic features, and variable congenital anomalies involving the cardiac, urinary, and gastrointestinal systems. Most affected individuals die before 3 years of age. Note: The disease is caused by mutations affecting the gene represented in this entry. Ref.5
Sequence similarities	Belongs to the PIGG/PIGN/PIGO family. PIGN subfamily.
