For information and support
We partner with advocacy groups to advance a common mission to improve the lives of people affected by rare genetic disorders of obesity. As these independent organizations are closest to understanding the unique impacts of living with these rare disorders, they are uniquely suited to most effectively address these needs. Working together, we strive to help support their vital work, and provide education and resources to the rare genetic disorders of obesity community.
