Rare Genetic Variants Increase Risk for Tourette Syndrome
(WorldNews Health)

An international team of 57 scientists from 11 countries has identified the first definitive risk genes for Tourette syndrome (TS), a complex neuropsychiatric disorder. The breakthrough came when researchers focused on a relatively new area of genomics research that involves looking at the entire genome, rather than searching for a particular gene, said Dr. Peristera Paschou, Purdue University associate biology professor. “Most times we focus on a mutation of a single base pair, which are the building blocks of DNA, and look for a mutation. But in recent years we’ve realized that there is another type of variation of the human genome,” said Paschou....
