Summaries for GCNT2 Gene

Entrez Gene Summary for GCNT2 Gene

  • This gene encodes the enzyme responsible for formation of the blood group I antigen. The i and I antigens are distinguished by linear and branched poly-N-acetyllactosaminoglycans, respectively. The encoded protein is the I-branching enzyme, a beta-1,6-N-acetylglucosaminyltransferase responsible for the conversion of fetal i antigen to adult I antigen in erythrocytes during embryonic development. Mutations in this gene have been associated with adult i blood group phenotype. Alternatively spliced transcript variants encoding different isoforms have been described.

Polymorphic Variants from UniProtKB/Swiss-Prot for GCNT2 Gene

GCNT2 is involved in determining the blood group I system (Ii) [MIM:110800]. The i (fetal) and I (adult) antigens are determined by linear and branched poly-N-acetyllactosaminoglycans, respectively. A replacement during development of i by I is dependent on the appearance of a beta-1,6-N-acetylglucosaminyltransferase, the I-branching enzyme. The expression of the blood group I antigen in erythrocytes is determined by isoform C of GCNT2.

  • Cataract 13, with adult i phenotype (CTRCT13) [MIM:116700]: An opacification of the crystalline lens of the eye that frequently results in visual impairment or blindness. Opacities vary in morphology, are often confined to a portion of the lens, and may be static or progressive. In general, the more posteriorly located and dense an opacity, the greater the impact on visual function. CTRCT13 is associated with the rare adult i phenotype, in which adult red blood cells are rich in i antigen and contain low levels of I antigen. {ECO:0000269 PubMed:11739194}. Note=The disease is caused by mutations affecting the gene represented in this entry.
