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 ]
48,XXYY syndrome is a condition related to the X and Y chromosomes (the sex chromosomes). People normally have 46 chromosomes in each cell.Two of the 46 chromosomes, known as X and Y, are called sex chromosomes because they help determine whether a person will develop male or female sex characteristics.
The following is a list of genetic disorders and if known, type of mutation and for the chromosome involved. Although the parlance "disease-causing gene" is common, it is the occurrence of an abnormality in the parents that causes the impairment to develop within the child.
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 ...
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.
Pre-clinical obesity refers to excess fat without organ dysfunction but increased risk of developing clinical obesity and other long-term health problems such as cardiovascular disease, and Type 2 ...
Preclinical obesity refers to excess body fat without current health issues but with increased risks of conditions like type 2 diabetes, heart disease, and certain cancers. Early interventions can ...
