Fenotipos de obesidad y su asociación con el polimorfismo Pro12Ala del gen PPARƴ2 en mujeres de 18 a 50 años. por Robles Camporredondo, Gabriela

“…With the results of their genetic analysis (rs1801282 polymorphism), obtained by PCR-RT, genotypic and allelic frequencies were calculated; subsequently the association between Pro12Ala polymorphism of PPAR2 gene with the obesity phenotypes identified in the study population was evaluated employing a lineal regression statistical model. Results: participants were cataloged like “Normal weight obese” (42%), “Metabolically healthy obese” (23%), “Metabolically unhealthy obese” (19%), “Normal weight lean” (14%) and “Metabolically obese normal weight” (2%). …”
