为了确定区分HLA-B*37:119和已知的HLA-B等位基因的特定遗传变异.

主要方法:

对HLA-B基因的序列分析.
新型等位基因序列与参考HLA序列的比较.

主要成果:

新的等位基因HLA-B*37:119被确定并测序.
研究人员发现,在4号外子中单个非同义的核酸替代能使HLA-B*37:119与HLA-B*37:01:01:01.区分开来.

结论:

HLA-B*37:119代表了HLA-B位点内的一个独特的遗传变异.
这种特定的核酸变化可能对免疫识别和HLA类型有影响.

Genome-wide Association Studies-GWAS

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.
GWAS does not require the identification of the target gene involved in...
