Genes and anorexia
A team of researchers from the Center for Applied Genomics at The Children's Hospital of Philadelphia has been looking into the genetics of anorexia nervosa. They studied 4,736 people, 1,003 of whom had anorexia and compared their genes. The study found that variations in two genes - OPRD1 and HTR1D - increased the risk of developing the condition. However, most scientists think that although genes might increase the risk of developing mental-health problems the true causes of these conditions lie in a combination of genetics and people's upbringing and experiences.
