Summaries for ALG12 Gene

Entrez Gene Summary for ALG12 Gene

  • This gene encodes a member of the glycosyltransferase 22 family. The encoded protein catalyzes the addition of the eighth mannose residue in an alpha-1,6 linkage onto the dolichol-PP-oligosaccharide precursor (dolichol-PP-Man(7)GlcNAc(2)) required for protein glycosylation. Mutations in this gene have been associated with congenital disorder of glycosylation type Ig (CDG-Ig)characterized by abnormal N-glycosylation. [provided by RefSeq, Jul 2008]

GeneCards Summary for ALG12 Gene

ALG12 (ALG12, Alpha-1,6-Mannosyltransferase) is a Protein Coding gene. Diseases associated with ALG12 include congenital disorder of glycosylation, type ig and alg12-congenital disorder of glycosylation. Among its related pathways are Biosynthesis of the N-glycan precursor (dolichol lipid-linked oligosaccharide, LLO) and transfer to a nascent protein and Biosynthesis of the N-glycan precursor (dolichol lipid-linked oligosaccharide, LLO) and transfer to a nascent protein. GO annotations related to this gene include alpha-1,6-mannosyltransferase activity and dol-P-Man:Man(7)GlcNAc(2)-PP-Dol alpha-1,6-mannosyltransferase activity.

Disorders for ALG12 Gene

(1) OMIM Diseases for ALG12 Gene (607144)


  • Congenital disorder of glycosylation 1G (CDG1G) [MIM:607143]: A multisystem disorder caused by a defect in glycoprotein biosynthesis and characterized by under-glycosylated serum glycoproteins. Congenital disorders of glycosylation result in a wide variety of clinical features, such as defects in the nervous system development, psychomotor retardation, dysmorphic features, hypotonia, coagulation disorders, and immunodeficiency. The broad spectrum of features reflects the critical role of N-glycoproteins during embryonic development, differentiation, and maintenance of cell functions. {ECO:0000269 PubMed:11983712, ECO:0000269 PubMed:12736397, ECO:0000269 PubMed:17506107}. Note=The disease is caused by mutations affecting the gene represented in this entry.
