Effects of the FTO gene on lifestyle intervention studies in children.
The effects of FTO on body weight, body composition, and the risk of developing overweight and obesity in children, adolescents, and adults are analyzed in this review. Most trails have been conducted on the rs9939609 SNP of the FTO gene. The minor A-allele frequency ranged from 0.38 to 0.49 in different European populations. Briefly, it has been reported that overweight-obesity risk per A-alle...
متن کاملDietary Intake, FTO Genetic Variants, and Adiposity: A Combined Analysis of Over 16,000 Children and Adolescents
The FTO gene harbors variation with the strongest effect on adiposity and obesity risk. Previous data support a role for FTO variation in influencing food intake. We conducted a combined analysis of 16,094 boys and girls aged 1-18 years from 14 studies to examine the following: 1) the association between the FTO rs9939609 variant (or a proxy) and total energy and macronutrient intake; and 2) th...
متن کاملThe FTO gene rs9939609 obesity-risk allele and loss of control over eating.
BACKGROUND Children with rs9939609 FTO variant alleles (homozygous = AA and heterozygous = AT) are predisposed to greater adiposity than are those with 2 wild-type alleles (TT). OBJECTIVE Because FTO is highly expressed in hypothalamic regions that are important for appetite, FTO genotype may affect energy balance by influencing eating behavior. Loss of control (LOC) eating, a behavior common...
متن کاملObesity associated genetic variation in FTO is associated with diminished satiety.
CONTEXT Polymorphisms within the FTO gene have consistently been associated with obesity across multiple populations. However, to date, it is not known whether the association between genetic variation in FTO and obesity is mediated through effects on energy intake or energy expenditure. OBJECTIVE Our objective was to examine the association between alleles of FTO known to increase obesity ri...
متن کاملPolymorphisms of the FTO gene are associated with variation in energy intake, but not energy expenditure.
The FTO gene has significant polymorphic variation associated with obesity, but its function is unknown. We screened a population of 150 whites (103F/47M) resident in NE Scotland, United Kingdom, for variants of the FTO gene and linked these to phenotypic variation in their energy expenditure (basal metabolic rate (BMR) and maximal oxygen consumption VO(2)max) and energy intake. There was no si...
