Research Study Subject Recruitment

Interaction of Melatonin and MTNR1B Genotype on Glucose Control

Brigham and Women's Hospital researchers need you! Looking for adults between the ages of 21-55.

This study will be performed in healthy individuals with genetic variation in a gene called MTNR1B. This gene influences the regulation of blood sugar and has been associated with type 2 diabetes risk. Your genes are passed down from your parents and then passed on to your children. If you are eligible and interested in enrolling in our research study we collect a saliva or blood sample to test your genetic material for the MTNR1B genetic variation.


Prospective subjects must be healthy Caucasian non-smokers between the ages of 21-55, live in New England, and off most medications (birth control is acceptable).
