BU CTE Center researchers have identified a gene linked to CTE-related outcomes
After 10 years of studying brains donated by families of deceased military servicepeople, football players, and other contact-sport athletes, researchers from the BU School of Medicine and the VA Boston Healthcare System have amassed more than 600 brains, a collection they say has grown large enough to enable meaningful analysis of the genetics related to chronic traumatic encephalopathy (CTE).
Their latest discovery—about the CTE-related significance of genetic variation in a gene called TMEM106B—could explain why similar levels of head trauma in different people can cause some of them to suffer more drastic symptoms of CTE than others. The findings are described in a study published in Acta Neuropathologica Communications November 3, 2018.
