Scientists report finding gene mutations connected to eating disorders

Scientists have discovered two gene mutations that they believe are associated with an increased risk of eating disorders. Anorexia nervosa and bulimia often run in families, but these eating disorders are complex, and it has proved difficult  to identify the paths. But, using two families with very high incidences of eating disorders, scientists say they found rare mutations, one in each family, that were associated with the people who had the disorders. The study suggests Read More

Personality may be key to genetics of bipolar disorder

People with bipolar disorder vary significantly from their unaffected relatives, and from healthy controls, on several measures of personality, a study shows. Furthermore, genetic analysis revealed suggestive linkage peaks for those traits that were heritable, potentially proving useful for the identification of genes underlying susceptibility to bipolar disorder. “The results of our analyses suggest that personality dimensions may have utility in dissecting the genetic architecture of BD [bipolar disorder],” the researchers write in the Journal Read More
