Notably, the findings across these studies were consistent, showing that none of the genetic variants were linked to obesity, except for LEP G2548A [23], which may be associated with overweight/obesity among Indian males; UCP2 45 bp I/D [27] with overall adiposity among Malaysian women; and DRD2 polymorphisms with eating behavior but not with obesity [39,44]. Here, UCP2 is linked to obesity due to melanocortin 4 receptor deficiency.
