B3GALT2
B3GALT2: A Key Enzyme in Human Health
Description
B3GALT2 (beta-1,3-galactosyltransferase 2) is an enzyme involved in the synthesis of glycoproteins, which are complex molecules composed of proteins and carbohydrates. Glycoproteins play essential roles in various cellular processes, including cell-cell communication, immune responses, and cell signaling. B3GALT2 is specifically responsible for the addition of galactose, a type of sugar, to the sugar chains attached to these glycoproteins.
Associated Diseases
Mutations in the B3GALT2 gene have been linked to several inherited disorders, including:
- Familial dysautonomia: A rare genetic disorder characterized by a lack of certain reflexes, autonomic dysfunction, and feeding difficulties.
- Congenital muscular dystrophy type 1D: A severe muscle-weakening disease that affects newborns.
- EIEE2 (Early Infantile Epileptic Encephalopathy, Type 2): A rare epileptic disorder that results in severe developmental delays and seizures.
- Congenital hydrocephalus: An accumulation of fluid in the brain that can lead to increased head size and developmental problems.
Did you Know ?
Approximately 1 in 25,000 people worldwide are affected by familial dysautonomia, the most common disorder associated with B3GALT2 mutations.
