Summary
Genetic variations in the RORA gene, specifically rs11639084 and rs4774388, are strongly associated with severe obesity in the Iranian population, highlighting RORα
Area of Science:
- Genetics
- Metabolic Disorders
- Molecular Biology
Background:
- RORα (Retinoid-related Orphan Receptor Alpha) is a nuclear receptor transcription factor.
- RORα plays a role in regulating metabolic processes and has been implicated in conditions such as obesity.
Purpose of the Study:
- To investigate the association between two specific single nucleotide polymorphisms (SNPs) in the RORA gene (rs11639084 and rs4774388) and severe obesity.
- To identify potential genetic risk factors for obesity within the Iranian population.
Main Methods:
- Case-control study design.
- Genotyping of RORA gene polymorphisms rs11639084 and rs4774388 in an Iranian cohort.
- Statistical analysis including allelic, co-dominant, and recessive genetic models to assess SNP-obesity associations.
Main Results:
- Both rs11639084 and rs4774388 SNPs showed a significant association with severe obesity (P < 0.0001).
- The T allele of rs11639084 (OR = 16.85) and the C allele of rs4774388 (OR = 4.61) were identified as risk alleles.
- Specific genotypes (TT for rs11639084 and CC for rs4774388) demonstrated strong associations with obesity under different genetic models.
Conclusions:
- The RORA gene, through polymorphisms rs11639084 and rs4774388, contributes to the pathogenesis of severe obesity in the Iranian population.
- These findings suggest RORα as a potential therapeutic target for obesity management.

Obesity
498
The Body Mass Index (BMI) is a numerical value derived from a person's weight and height, used to categorize individuals into weight ranges. It is calculated using the formula: weight in kilograms divided by height in meters squared. Obesity is a health condition characterized by excessive accumulation of adipose tissue that poses health risks, often diagnosed with a BMI ≥ 30. This excess fat storage occurs when surplus dietary calories are converted into triglycerides and stored in...

Single Nucleotide Polymorphisms-SNPs
15.0K
A single nucleotide polymorphism or SNP is a single nucleotide variation at a specific genomic position in a large population. It is the most prevalent type of sequence variation found in the human genome. Point mutations that occur in more than 1% of the population qualify as SNPs. These are present once every 1000 nucleotides on an average in the human genome. Replacement of a purine with another purine (A/G) or a pyrimidine with another pyrimidine (C/T) is known as a transition. In contrast,...

Agouti: A Lethal Allele
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...

Human Genetics

Human genetics provides a profound framework for understanding the interplay between genetic predispositions and human psychology. At the heart of this discipline lies the study of how genes influence physical traits, behaviors, and susceptibility to diseases. Each person carries a unique genetic code that subtly or significantly shapes their psychological and behavioral landscape.

Genome-wide Association Studies-GWAS
13.4K
Genome-wide association studies or GWAS are used to identify whether common SNPs are associated with certain diseases. Suppose specific SNPs are more frequently observed in individuals with a particular disease than those without the disease. In that case, those SNPs are said to be associated with the disease. Chi-square analysis is performed to check the probability of the allele likely to be associated with the disease.
GWAS does not require the identification of the target gene involved in...

mTOR Signaling and Cancer Progression
3.8K
The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.
