What is the official name of the B3GALTL gene?
The official name of this gene is “beta 1,3-galactosyltransferase-like.”
B3GALTL is the gene's official symbol. The B3GALTL gene is also known by other names, listed below.

What is the normal function of the B3GALTL gene?
The B3GALTL gene provides instructions for making an enzyme called beta-1,3-glucosyltransferase (B3Glc-T), which is involved in the complex process of adding sugar molecules to proteins (glycosylation). Glycosylation allows proteins to perform a wider variety of functions. The B3Glc-T enzyme is responsible for one step in a glycosylation pathway that adds a sugar molecule called glucose to several different proteins. The B3GALTL gene is normally turned on in most cells of the body, which suggests that the B3Glc-T enzyme plays an important role in cellular function.
How are changes in the B3GALTL gene related to health conditions?
