Brief Summary: this large patient cohort study identified an overrepresentation of functionally damaging variants in MC3R in individuals with constitutional delay of growth and puberty but not in patients with IHH.Melanocortin 3 receptor (MC3R) is a permissive signal expressed by hypothalamic kisspeptin-neurokinin B-dynorphin (KNDY) neurons. It activates puberty through the leptin-proopiomelanocortin pathway in response to nutritional signaling<...
