Gene function

Influences hunger, satiety, and energy expenditure

Analyzed variants (SNPs)

rs1558902 FTO rs1558902 Population frequency: 41.0% Chr. 16 : 53,803,574
Genotype Impact What it means
TT (Normal) Normal Lower genetic predisposition to weight gain.
TA (Carrier) Low impact Moderate increased appetite and weight gain tendency. Physical activity helps offset this.
AA (Variant) Moderate Higher appetite and weight gain tendency. Regular exercise and protein-rich diet essential.
