Major genetic study confirms that many genes contribute to risk for Tourette’s syndrome

March 5, 2019 dna 0
A meta-analysis of multiple studies into the genetic background of Tourette’s syndrome (TS) — a neurodevelopmental disorder characterized by chronic involuntary motor and vocal tics — finds that variants in hundreds of genes, working in combination, contribute to the development of the syndrome and suggests that Tourette’s is part of a continuous spectrum of tic disorders, ranging from mild, sometimes transient tics to severe cases that can include psychiatric symptoms.

Discovery of the genetic ‘conductor’ of brain stem cells

March 5, 2019 dna 0
Our brain comprises 85 billion nerve cells and just as many so-called glial cells. But what decides when and how many of them become neurons or glial cells? A new study has shown how the Foxg1 gene plays a fundamental role in piloting the differentiation of stem cells, guaranteeing that neurons and glial cells are produced in the right quantity and at the right moment. The research opens new roads to understanding and treating incurable genetic diseases.

Could genetic breakthrough finally help take the sting out of mouth ulcers?

March 5, 2019 dna 0
A large breakthrough has been made in the genetic understanding of mouth ulcers which could provide potential for a new drug to prevent or heal the painful lesions. Mouth ulcers affect up to 25 percent of young adults and a higher proportion of children. Previous research has shown that mouth ulcers are partially heritable, but until now there has been little evidence linking specific genes or genomic regions to mouth ulcers.
