GLT8D1: new gene identifies novel disease mechanism

MND Association-supported clinical fellow Dr Johnathan Cooper-Knock, and a PhD student Tobias Moll, report mutations in a new MND gene which has uncovered a previously unknown disease mechanism. The new MND causing gene holds instructions for a class of proteins, called glycosyltransferase (GLT8D1), which has not previously been associated with neurodegeneration.

During the experiments, published in the journal Cell Reports, the research team read the genetic code from two related patients with an unknown familial (inherited) form of MND and found a change in the gene that makes an enzyme called GLT8D1. They went on to examine a larger sample of 103 people with inherited MND and found that five of these also had this gene abnormality, indicating that this change causes MND. Because the enzyme and its mechanism have never previously been associated with MND, this study has uncovered a new genetic and biological cause of the disease.Read More »
