Red List (low evidence)

PMID: 9753710. In a German obesity cohort, 4 individuals heterozygous for a p.Pro115Gln mutation were markedly more obese than the other 117 obesity participants. Age of the 4 carriers ranged from 32-74 years, not early onset. 3/4 also had type 2 diabetes. In vitro analyses showed a permanent activation of PPARg2 that led to an accelerated rate of adipocyte differentiation and increased fat accumulation in a tissue-culture model of adipogenesis.

PMID: 9425261. In a Caucasian cohort of 26, with type 2 diabetes and many with obesity, missense p.Pro12Ala was identified. This variant has 1977 homozygotes in gnomAD.

PPARG variants known to cause familial partial lipodystrophy.
