PMID 31700171.These authors sequenced the gene for melanocortin-2 receptor accessory protein (MRAP2 ) in 9418 blood DNA samples from several population studies. They detected 23 rare heterozygous variants, which were significantly associated with an increased risk of obesity (OR 3.8 in children and 2.9 in adults)....
