The Apolipoprotein A-II (APOA2) gene is associated with the synthesis of Apolipoprotein 2, the second most common protein found in the high density lipoprotein. This protein is shown to be associated with the impairment of the reverse cholesterol transport and the anti-oxidant ability of the high density lipoprotein. People with the T variant of the gene have higher levels of the protein.
Association with Saturated Fat Intake and Weight Gain Tendency:
In a study conducted on adolescents, people with the C variant were found to be associated with greater body fat percentage, visceral fat and HDL-C levels on a high saturated fat intake.
When people with the C variant are given a choice between a bar of chocolate and guacamole, they are more likely to prefer a bar of chocolate, though there is an equal amount of fat in both. This may be because people with C variant are more likely to prefer foods that are rich in saturated fat.
In another study conducted on nearly 2000 individuals, people with the C variant were found to be significantly associated with a higher intake of high fat dairy and higher BMI.
