Genetic factors significantly influence obesity, a condition often caused by gene mutations affecting the leptin/melanocortin pathway. This review covers genes linked to genetic obesity and relevant genetic testing methods.
Area of Science:
- Genetics
- Endocrinology
- Metabolism
Background:
- Obesity is a complex condition with significant heritability, resulting from genetic and environmental interactions.
- It stems from a sustained imbalance between energy intake and expenditure.
- A small percentage (5%) of non-syndromic obesity cases are monogenic, known as Mendelian obesity.
Purpose of the Study:
- To review genes implicated in genetic obesity.
- To describe genetic analysis methods for diagnosing obesity.
Main Methods:
- Literature review of genes associated with genetic obesity.
- Description of genetic testing techniques used for analysis.
Main Results:
- Identified key genes involved in the regulation of adipose tissue, primarily focusing on the leptin/melanocortin pathway.
- Detailed the genetic mutations causing Mendelian obesity, often linked to leptin signaling.
Conclusions:
- Genetic factors, particularly mutations in the leptin/melanocortin pathway, play a crucial role in Mendelian obesity.
- Genetic analysis is essential for identifying the underlying causes of certain obesity cases.

Lucien Cuénot discovered lethal alleles in 1905 while studying the inheritance of coat color in mice. The agouti gene is responsible for the color of the coat in mice. This gene codes for an agouti-signaling protein, which is responsible for melanin distribution in mammals. The wild-type allele gives rise to gray-brown coat color in mice, while the mutant allele gives rise to yellow coat color. In addition to coat color, the agouti gene is associated with the yellow...
