New study discovers a potential cure for leukodystrophy, a disease that affects brain white matter in children. Fingolimod, a drug currently used to treat multiple sclerosis may be used to counteract the gene that causes the disease.
Gene Responsible for Childhood Neurodegenerative Disorders Identified
Mutated gene responsible for three forms of leukodystrophies has been identified by scientists.

‘New study offers hope in curing leukodystrophy, a novel disease that affects the brain white matter in children. The gene that causes the disease is called DEGS1, and its defect may be counteracted with fingolimod, a drug currently used to treat multiple sclerosis.’
The gene causing the disorder is called DEGS1 and was identified using whole exome sequencing (WES) of 19 patients from around the globe (China, Iran, Morocco, USA, and France). "Sample collection for such a rare disease was extremely fast thanks to our collaboration with reference centers for leukodystrophies in France (Dr. Odile Boespflug-Tanguy) and in Baltimore (Dr. Ali Fatemi), and to the freely accessible genomic information exchange platform GeneMatcher," Dr. Pujol explains. DEGS1 is an enzyme of lipid metabolism that converts dihydroceramides to ceramides, at a hub essential for brain function. Indeed, defects in other enzymes along this pathway cause similar rare diseases like Krabbe disease or Metachromatic Leukodystrophy, also affecting the myelin.
A zebrafish model with deficient DEGS1 function was generated in the laboratory of Dr. Cristina Pujades, UPF Barcelona, and exhibited swimming difficulties, loss of myelin forming cells (oligodendrocytes) and ceramide imbalances. These defects were corrected by a treatment with fingolimod, a drug in use for multiple sclerosis which interferes with this pathway.
