To read the full abstract: J Clin Endocrinol Metab. 2018 Feb 1;103(2):649-659A minimum level of energy availability is required for the onset of puberty, whereas increased fat mass has been shown to be associated with precocious onset of puberty1,2. Recent genome-wide association studies have identified several loci for age at menarche also associated with obesity3-5. Whethe...

To read the full abstract: Eur J Endocrinol. 2018 Apr;178(4):377-388[Comments on 7.7 and 7.8] Familial self-limited delayed puberty is highly heritable and has a clear genetic basis as described in the review written by Sasha Howard. Recent studies suggest that the genetic basis of self-limited delayed puberty is likely to be highly heteroge...

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<...
