概括

这项研究发现,在坦桑尼亚,HLA单元类型和点头综合征 (NS) 或相关之间没有显著的遗传联系. 需要对更大的样本大小进行进一步的研究,以探索NS易感性的潜在宿主遗传因素.

科学领域:

遗传学是一个遗传学.
神经学神经学
免疫学免疫学免疫学

背景情况:

点头综合征 (NS) 是一种残疾的儿童,与性有关.
高瘤性卷积菌感染是危险因素,但遗传敏感性可能会影响NS的发展.
人类白细胞抗原 (HLA) 基因正在研究它们在感染性和自身免疫性疾病易感性中的作用.

研究的目的:

在坦桑尼亚调查HLA单元型和相关 (OAE),包括NS之间的关联.
为了确定特定的HLA基因是否会增加对OAE或O. volvulus感染的敏感性.

主要方法:

坦桑尼亚的一项病例控制研究包括98名患者和112名对照患者.
来自干血斑点的DNA经历了基于HLA序列的11个位置的类型化.
数据分析了与O. volvulus血清阳性,,OAE和NS的关联,使用邦费罗尼校正.

主要成果:

抗Ov16血清阳性在病例中比对照 (58.9%) 高 (76.5%).
在校正后,没有发现与,OAE,NS或抗Ov16血清阳性具有统计学意义的HLA关联.
潜在的关联 (预纠正) 包括的HLA-C07:01,OAE的HLA-DQB106:02和NS的HLA-B35:01.

结论:

这项研究没有发现坦桑尼亚的HLA与OAE或NS有显著的关联.
正如之前的研究表明的那样,HLA-B*35:01是进一步研究的潜在候选者.
需要进行更大规模的多国研究来确认宿主对OAE和NS敏感性的遗传贡献.

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...

Single Nucleotide Polymorphisms-SNPs

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,...
