Like many other medical conditions, obesity is the result of an interplay between environmental and genetic factors. [2] [3] Studies have identified variants in several genes that may contribute to weight gain and body fat distribution, although only in a few cases are genes the primary cause of obesity.
Fat mass and obesity-associated protein, also known as alpha-ketoglutarate-dependent dioxygenase FTO, is an enzyme that in humans is encoded by the FTO gene located on chromosome 16. As one homolog in the AlkB family proteins, it is the first messenger RNA (mRNA) demethylase that has been identified. [ 5 ]
The first complete telomere-to-telomere sequence of a human autosomal chromosome, chromosome 8, followed a year later. [70] The complete human genome (without Y chromosome) was published in 2021, while with Y chromosome in January 2022. [3] [4] [71] In 2023, a draft human pangenome reference was published. [8]
Monogenic obesity is excess weight caused by a mutation in a single gene, as opposed to syndromic obesity not tied to a single gene variation and most obesity, which is caused by multiple genetic and environmental risk factors. Monogenetic obesity mostly affects the hypothalamus and leptin–melanocortin system (see hypothalamic obesity ...
Obesity is a disease characterized by having excessive body fat, increasing a person’s risk for many serious health problems, such as heart disease, diabetes, and even some cancers.
A Human Genome Equivalent (HuGE) review in 2004 looked at studies of the connection between genetic mutations affecting leptin regulation and obesity. They reviewed a common polymorphism in the leptin gene (A19G; frequency 0.46), three mutations in the leptin receptor gene (Q223R, K109R, and K656N) and two mutations in the PPARG gene (P12A and ...
New guidance from a team of health experts around the world proposes expanding the definition of obesity beyond the popular body mass index (BMI) measure. The commission recommends the inclusion ...
