Abstract

Obesity is a serious international health problem that increases the risk of several common diseases. The genetic factors predisposing to obesity are poorly understood. A genome-wide search for type 2 diabetes–susceptibility genes identified a common variant in the FTO (fat mass and obesity associated) gene that predisposes to diabetes through an effect on body mass index (BMI). An additive association of the variant with BMI was replicated in 13 cohorts with 38,759 participants. The 16% of adults who are homozygous for the risk allele weighed about 3 kilograms more and had 1.67-fold increased odds of obesity when compared with those not inheriting a risk allele. This association was observed from age 7 years upward and reflects a specific increase in fat mass.

  • The FTO gene influences hypothalamic regulation of appetite and energy expenditure by modulating leptin and melanocortin signaling pathways.

    “Key genes, such as the fat mass and obesity-associated gene (FTO), influence hypothalamic regulation of appetite and energy expenditure by modulating leptin and melanocortin signaling pathways [22].”

    From Obesity: Clinical Impact, Pathophysiology, Complications, and Modern Innovations in Therapeutic Strategies (2025) · cites this paper as [22]

    The paper reports that FTO variation is associated with BMI and obesity, and that FTO expression is highest in the brain (passages indexed under Abstract; page unavailable). It does not establish hypothalamic regulation of appetite or energy expenditure through leptin and melanocortin signaling. Instead, it describes FTO as having an unknown function in an unknown pathway and calls for further work to identify the mechanism. (LLM, conf=0.88)

  • The 16% of sedentary adults homozygous for the risk allele AA in rs9939609 in the FTO gene weighed about 3 kg more and had 1.67-fold increased odds of obesity compared with those not inheriting a risk allele.

    “The 16% of sedentary adults who are homozygous for the risk allele of AA in rs9939609 in the fat mass and obesity-associated (FTO) gene weighed ~3 kg more and had 1.67-fold increased odds of obesity when compared with those not inheriting a risk allele (191).”

    From Lack of Exercise Is a Major Cause of Chronic Diseases (2012) · cites this paper as [191]

  • Similar results were also obtained using a genetic risk score based solely on the SNP in the FTO gene.

    “Secondly, similar results were also obtained using a genetic risk score based solely on the SNP in the FTO gene, which is a gene that has been found to be associated with BMI in numerous studies, where none of the cohorts used in the present study were included [34–36].”
  • Variants at the four BMI loci have also been associated with childhood BMI.

    “Variants at these four loci have also been associated with childhood BMI18–20”
  • Four novel loci for menarche were previously identified by GWA studies for adult BMI: rs9939609 (in/near FTO, P=3.1×10−8), rs633715 (SEC16B, P=2.1×10−8), rs2002675 (TRA2B, ETV5, P=1.2×10−9) and rs2947411 (TMEM18, P=1.7×10−8).

    “Four novel loci for menarche were previously identified by GWA studies for adult BMI18–20; these were rs9939609 (in/near FTO, P=3.1×10−8), rs633715 (SEC16B, P=2.1×10−8), rs2002675 (TRA2B, ETV5, P=1.2×10−9) and rs2947411 (TMEM18, P=1.7×10−8).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
