How are FTO and Haut related?

The relationship between the FTO gene and skin is indirect and not yet well established. FTO (Fat Mass and Obesity Associated) is primarily known for its strong association with body weight and fat mass. Some mechanistic studies suggest that FTO, as an RNA demethylase, may influence gene expression in skin cells – potentially affecting collagen synthesis, pigmentation, or wound healing. Links to skin aging or UV sensitivity have been proposed, but robust human studies are lacking. Direct skin phenotypes like wrinkling or elasticity cannot be reliably predicted by single FTO SNPs. Consumer DNA tests like MyBody-X typically report FTO variants in the context of weight management, not skin traits. The evidence level is mechanistic or unclear. Skin diagnosis or advice based solely on FTO genotypes is not recommended.
