p.Q223R leptin receptor polymorphism associated with obesity in Brazilian multiethnic subjects

Article Abstract:

The possible association between the leptin receptor (LEPR) p.Q223R gene polymorphism and its role in the obese phenotype in selected obese subjects from a Brazilian multiethnic population is tested, and the results compared with those obtained from a sample of lean or normal healthy subjects. A significant difference is observed in LEPR p.Q223R polymorphism frequency in obese and lean subjects, leading to the conclusion that obesity in Brazil is strongly associated with it.

Regional differences in the genetic variability of Finno-Ugric speaking Komi populations

Article Abstract:

Genetic variability was assessed in two geographically distinct populations, the Izhemski and Priluzski Komi who occupy an extensive territory in north Russia. The results exposed some relation between Priluzski Komi and Eastern Slavonic populations.
