Effects of Leptin Replacement in Children
February 11, 2020 updated by: Richard Bookman, University of Miami
To assess the endocrine and immune effects of leptin replacement in leptin-deficient children, from a consanguineous family.
The hypothesis is that leptin replacement will have significant effects on endocrine function.
