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.
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 ...
Chromosome 16 is one of the 23 pairs of chromosomes in humans. People normally have two copies of this chromosome. People normally have two copies of this chromosome. Chromosome 16 spans about 90 million base pairs (the building material of DNA) and represents just under 3% of the total DNA in cells .
16p11.2 deletion syndrome is a rare genetic condition caused by microdeletion on the short arm of chromosome 16. Most affected individuals experience global developmental delay and intellectual disability, as well as childhood-onset obesity. [1] 16p11.2 deletion is estimated to account for approximately 1% of autism spectrum disorder cases. [3] [4]
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.
In eukaryotes, such as humans, roughly 3.2 billion nucleotides are spread out over 23 different chromosomes (males have both an X chromosome and a Y chromosome instead of a pair of X chromosomes as seen in females). Each chromosome consists enormously long linear DNA molecule associated with proteins that fold and pack the fine thread of DNA ...

Pathophysiology of obesity is the study of disordered physiological processes that cause, result from, or are otherwise associated with obesity. A number of possible pathophysiological mechanisms have been identified which may contribute in the development and maintenance of obesity.
