Summary
The Human Leukocyte Antigen (HLA)-DQA1*01:169 allele features a specific genetic alteration. This single nucleotide substitution occurs in codon 175 within exon 3, defining its unique molecular characteristic.
Area of Science:
- Immunogenetics
- Molecular Biology
Background:
- Human Leukocyte Antigen (HLA) genes are crucial for immune response.
- Allelic variations within HLA loci contribute to diverse immune functions and disease susceptibility.
Purpose of the Study:
- To characterize the specific genetic makeup of the HLA-DQA1*01:169 allele.
- To identify the molecular basis of this particular HLA allele.
Main Methods:
- Sequence analysis of the HLA-DQA1 gene.
- Identification of single nucleotide polymorphisms (SNPs) within coding regions.
Main Results:
- The HLA-DQA1*01:169 allele is defined by a single nucleotide substitution.
- This substitution is located at codon 175 in exon 3 of the HLA-DQA1 gene.
Conclusions:
- The precise genetic signature of HLA-DQA1*01:169 has been identified.
- This characterization provides a foundation for further immunogenetic and clinical studies involving this allele.

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.

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.
