|May 8, 2013
Summary
The human leukocyte antigen (HLA) A*02:129 allele was identified and characterized. It differs from the HLA-A*02:87 allele by specific nucleotide variations in exon 2.
Area of Science:
- Immunogenetics
- Molecular biology
Background:
- The human leukocyte antigen (HLA) system plays a crucial role in immune response.
- Specific HLA alleles are associated with various immune-related conditions and drug hypersensitivities.
Purpose of the Study:
- To report the identification and characterization of a novel HLA-A allele, designated HLA-A*02:129.
- To detail the sequence differences between HLA-A*02:129 and a related allele, HLA-A*02:87.
Main Methods:
- Nucleotide sequencing of exons and flanking regions of the HLA-A gene.
- Comparison of obtained sequences with known HLA allele databases.
Main Results:
- A novel HLA-A allele, HLA-A*02:129, was identified.
- This new allele differs from HLA-A*02:87 by five nucleotide substitutions within exon 2 at positions nt 25, nt 29, nt 167 (T), nt 184, and nt 192.
Conclusions:
- The characterization of HLA-A*02:129 expands the known diversity of HLA-A alleles.
- Understanding these specific genetic variations is important for immunogenetic research and clinical applications.

Genome-wide Association Studies-GWAS
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.

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...

Blood Types
Human blood is classified into different types based on the presence of antigens on the red blood cell's surface and antibodies in the plasma. Proper identification of blood type is essential for successful blood transfusion. The International Society of Blood Transfusion has identified 38 human blood types based on the surface antigens on the red blood cells. The most common types are ABO, Rh, and MNS blood types.

Single Nucleotide Polymorphisms-SNPs
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,...
