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 ]
Symptoms of Obesity. Obesity symptoms can differ greatly from one person to another. But most symptoms show up because bodily systems have to work harder due to the excess weight.
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 ...
Since 2010, scientists have known that the Y chromosome is rapidly evolving in humans, but a new study shows that the same can be said across all Great Apes—the closest relatives to humans.
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 .
The study, which was published in Obesity Science & Practice earlier this year, is raising questions about the importance of these nutrients in weight loss. Here’s what a dietitian wants you to ...
