Association of IL33 and IL1RAP Polymorphisms With Acute Anterior Uveitis
Current Molecular Medicine
|February 10, 2018
Summary
Genetic variations in the IL1RAP gene are linked to acute anterior uveitis (AAU). This finding identifies IL1RAP as a potential genetic risk marker for AAU in Chinese populations.
Area of Science:
- Immunogenetics
- Ophthalmology
- Genetics
Background:
- Acute anterior uveitis (AAU) is a common cause of sudden vision loss and eye pain.
- Interleukin-33 (IL-33) and IL-1 receptor accessory protein (IL-1RacP) are key players in the innate immune system.
Purpose of the Study:
- To investigate the association between the IL33 and IL1RAP genes and AAU.
- To identify potential genetic risk factors for AAU.
Main Methods:
- Genotyping of ten single nucleotide polymorphisms (SNPs) using Sequenom Mass ARRAY.
- Recruitment of 549 AAU patients and 1080 healthy controls.
Main Results:
- The IL1RAP-rs3773978 polymorphism showed a significant association with AAU in Chinese patients.
- Increased frequency of the A allele and AA homozygosity of IL1RAP-rs3773978 was observed in AAU patients.
- Genetic correlations may vary based on HLA-B27, ankylosing spondylitis (AS) status, attack frequency, and laterality.
Conclusions:
- IL1RAP-rs3773978 can serve as a genetic risk marker for AAU.
- These findings contribute to understanding the genetic basis of uveitis, highlighting the role of IL-1 family genes.

Single Nucleotide Polymorphisms-SNPs
18.6K
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,...

Associative Learning
1.5K
Associative learning is a fundamental concept in behavioral psychology, wherein a connection is established between two stimuli or events, leading to a learned response. This process is critical in understanding how behaviors are acquired and modified. Conditioning, the mechanism through which associations are formed, can be divided into two main types: classical conditioning and operant conditioning, each elucidating different aspects of associative learning.

Association Areas of the Cortex
9.6K
Association areas are regions of the cerebral cortex that do not have a specific sensory or motor function. Instead, they integrate and interpret information from various sources to enable higher cognitive processes such as memory, learning, and decision-making. Some key association areas include the following:
Prefrontal Association Area: This area is located in the frontal lobe and is involved in planning, decision-making, and moderating social behavior. It connects with primary motor areas,...

Muscles of the Anterior Neck
4.9K
The anterior neck muscles are the group of muscles covering the front part of the neck. These muscles are classified into three subgroups. The first one is the superficial muscles, the most visible muscles in the front of the neck. It includes the platysma and sternocleidomastoid. The second group is the suprahyoid muscles, located above the hyoid bone. This group comprises the digastric, mylohyoid, geniohyoid, and stylohyoid. Lastly, the infrahyoid muscles are found below the hyoid bone and...

Factors Affecting Dissolution: Polymorphism, Amorphism and Pseudopolymorphism
755
Polymorphism refers to the existence of a drug substance in multiple crystalline forms, known as polymorphs. Recently, this term has been expanded to include solvates (forms containing a solvent), amorphous forms (non-crystalline forms), and desolvated solvates (forms from which the solvent has been removed).
Some polymorphic crystals possess lower aqueous solubility than their amorphous counterparts, leading to incomplete absorption. For instance, the oral suspension of Chloramphenicol, which...

Genome-wide Association Studies-GWAS
15.8K
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...
