(Newser) – Researchers have found a set of genetic alterations linked to the development of anorexia, LiveScience reports. The eating disorder had previously been thought to be highly heritable, but specific genetic markers hadn't been identified. If more are found, people at risk for the disorder could be identified early.

In the latest study, one of the areas with variations has been previously identified with autism. "The fact that they come up now in this disease, which is another sort of neural psychiatric disease, is in my view, very intriguing," says the lead researcher. Any potential links will be examined in further studies.
