Summary
A novel Human Leukocyte Antigen C (HLA-C) allele, HLA-C*15:255, was identified. It differs from a known allele, HLA-C*15:02:01, by five specific nucleotide substitutions in key gene regions.
Area of Science:
- Immunogenetics
- Molecular biology
Background:
- Human Leukocyte Antigen (HLA) genes are crucial for immune response.
- Allelic variations within HLA genes can impact immune function and disease susceptibility.
Purpose of the Study:
- To characterize a newly identified HLA-C allele, designated HLA-C*15:255.
- To detail the genetic differences between HLA-C*15:255 and a related known allele.
Main Methods:
- Nucleotide sequencing of the HLA-C gene.
- Comparative analysis of DNA sequences.
Main Results:
- The novel allele HLA-C*15:255 was identified.
- Five distinct nucleotide substitutions differentiate HLA-C*15:255 from HLA-C*15:02:01.
- These substitutions are located within exons 4 and 5 of the HLA-C gene.
Conclusions:
- The identification of HLA-C*15:255 expands the known HLA-C allele repertoire.
- Understanding these specific genetic variations is important for high-resolution HLA typing and immunological studies.

03:00Next-generation Sequencing
The first human genome sequencing project cost $2.7 billion and was declared complete in 2003, after 15 years of international cooperation and collaboration between several research teams and funding agencies. Today, with the advent of next-generation sequencing technologies, the cost and time of sequencing a human genome have dropped over 100 fold.
Next-Generation Sequencing Methods
Although all next-generation methods use different technologies, they all share a set of standard features.

01:05Single 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,...
01:11Genome-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.
