Second genetic link to weight and obesity
Date:5/4/2008

effect through action on MC4R.

"Our work to understand common disease, such as obesity, depends on the participation of thousands of people - members of the public who provide samples," explains Professor Nick Wareham, Director of the MRC Epidemiology Unit. "Without their willing participation, we could never achieve the power in our research to make striking findings like this.

"For each discovery, our efforts and the contribution of the participants will lead to improved healthcare for the population at large."

The team will now look to uncover how the DNA variants affect activity of the MC4R protein, which is a key player in orchestrating information from the body to control appetite and energy expenditure to keep body weight in balance. The team propose that altered activity of MC4R, imposed by the variants, might reduce its ability to carry out this important role.

The team emphasize that, although gene variants can affect weight, body mass index and obesity, they are only part of the story: lifestyle actions such as good diet and regular exercise are vital to control of weight.
