What is the official name of the ALG6 gene?
The official name of this gene is “ALG6, alpha-1,3-glucosyltransferase.”
ALG6 is the gene's official symbol. The ALG6 gene is also known by other names, listed below.

What is the normal function of the ALG6 gene?
The ALG6 gene provides instructions for making an enzyme that is involved in a process called glycosylation. Glycosylation is a process by which sugar molecules (oligosaccharides) are attached to proteins and fats. Oligosaccharides are made up of many sugar molecules that are attached to one another in a stepwise process forming a complex chain. Glycosylation modifies proteins so they can perform a wider variety of functions. The enzyme produced from the ALG6 gene transfers a simple sugar called glucose to the growing oligosaccharide. Once the correct number of sugar molecules are linked together, the oligosaccharide is attached to a protein or fat.
How are changes in the ALG6 gene related to health conditions?
