Possible Genetic Underpinning for Anorexia Discovered
Anorexia risk may be genetic, reports a new study in Molecular Psychology. The study was the largest ever conducted to look for genetic markers for anorexia and found both variations in gene sequences and in segments of DNA either duplicated or deleted. Study researcher Dr. Hakon Hakonarson, director of the Center for Applied Genomics at The Children’s Hospital of Philadelphia, and his colleagues scanned the genomes of 1,003 people with anorexia (whose average age was 27), and compared them with the genomes of 3,733 children (whose average age was 13) who did not have anorexia. The researchers found a few spots along the genome where the two groups differed and determined these “single-nucleotide polymorphisms (SNPs) could play a role in the genetic underpinnings of anorexia.
