Six new gene mutations linked to obesity
WASHINGTON (Reuters) –
At least six new gene mutations linked to obesity that point to ways the brain and nervous system control eating and metabolism have been identified, researchers reported Sunday.
Joel Hirschhorn at Children's Hospital and Harvard Medical School in Boston led a team called Genetic Investigation of Anthropometric Traits, or GIANT, to screen 15 different studies of the entire human genetic map and pinpoint the six new genetic variations.
The GIANT team found variations in six genes -- TMEM18, KCTD15, GNPDA2, SH2B1, MTCH2 and NEGR1 -- were strongly associated with the height-to-weight ratio known as body mass index (BMI).
