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.
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]

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.
The gene is located on the Q or long arm of chromosome 9 and is located near 9q34.3. MORM syndrome is an autosomal recessive congenital disorder [ 1 ] characterized by mental retardation , truncal obesity, retinal dystrophy , and micropenis ". [ 1 ]
In 2017, the U.S. Preventive Services Task Force, the expert panel that decides which treatments should be offered for free under Obamacare, found that the decisive factor in obesity care was not the diet patients went on, but how much attention and support they received while they were on it. Participants who got more than 12 sessions with a ...
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 .
Trisomy 21 – Down syndrome, an example of a polysomy at chromosome 21 Polysomy is a condition found in many species, including fungi, plants, insects, and mammals, in which an organism has at least one more chromosome than normal, i.e., there may be three or more copies of the chromosome rather than the expected two copies.
