From NCBI Gene:

This gene encodes a transmembrane protein that is located in the endoplasmic reticulum and is involved in GPI-anchor biosynthesis. The glycosylphosphatidylinositol (GPI) anchor is a glycolipid found on many blood cells and serves to anchor proteins to the cell surface. This gene is thought to encode a member of a family of dolichol-phosphate-mannose (Dol-P-Man) dependent mannosyltransferases. [provided by RefSeq, Jul 2008]

From UniProt:

Mannosyltransferase involved in glycosylphosphatidylinositol-anchor biosynthesis. Transfers the third alpha-1,2-mannose to Man2-GlcN-acyl-PI during GPI precursor assembly.

  • EPILEPTIC ENCEPHALOPATHY, EARLY INFANTILE, 80

From UniProt:

Epileptic encephalopathy, early infantile, 80 (EIEE80): A form of epileptic encephalopathy, a heterogeneous group of severe early-onset epilepsies characterized by refractory seizures, neurodevelopmental impairment, and poor prognosis. Development is normal prior to seizure onset, after which cognitive and motor delays become apparent. EIEE80 is an autosomal recessive form characterized by onset of refractory seizures in the first year of life, severe global developmental delay and/or intellectual disability. Additional variable features include polyneuropathy, hearing loss, visual impairment, dysmorphic or coarse facial features, and distal skeletal abnormalities. [MIM:618580]
