概括

亲属正常压力头症 (NPH) 影响大约10%的异常性NPH病例. 家庭NPH患者表现出比零星病例更好的认知能力和更多的震,发现了一种新的NEIL1基因变异.

科学领域:

神经学神经学
遗传学遗传学是一个

背景情况:

正常压力脑症 (NPH) 是一种综合症,其特征是由于脑脊液积聚而导致的行走障碍,尿失禁和认知衰退.
NPH可以是二次性,异常性或家族性,具有明显的临床和遗传特征.

研究的目的:

在临床,放射和手术反应方面比较零星和家族NPH病例.
识别与家族NPH相关的新型遗传突变.

主要方法:

对139名被评估为NPH的患者进行了回顾性分析,其中95人被诊断为异常性NPH (iNPH).
收集临床,放射和步态数据;评估家族病史和遗传模式.
整体外基因组测序用于识别家族NPH病例中的遗传变异.

主要成果:

在9.5%的病例中确定了家族性NPH,并显示出与零星NPH相似的人口统计数据.
家庭病例表现出明显更好的认知评分和更高的上肢动作震的发病率.
放射性标志物没有显著差异;两组都对心室外皮质疏通 (VPS) 反应良好.
在双胞胎患者中发现了一种新型的致病性NEIL1变异.

结论:

家庭NPH代表了iNPH的一个重要子集,呈现出明显的认知和震特征.
家庭NPH的遗传基础是异质的,NEIL1作为潜在的关联基因出现.

关键词:

一个家庭的家庭.正常压力水脑.这是零星的,零星的.

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...
