概括

在阿尔伯塔省,遗传性性 (HSP) 影响每10万人中有2.3人,在土著人口中患病率更高. 基因测试发现了17个基因的变异,突出显示了HSP基因的种族变异性.

科学领域:

神经学神经学
遗传学遗传学是一个
流行病学流行病学

背景情况:

遗传性性偏 (HSP) 是一种罕见的神经疾病,其特点是腿部性和步态障碍.
超过50%的HSP病例仍未在遗传上得到解决,对土著人口中HSP遗传学的理解有限.

研究的目的:

描述加拿大阿尔伯塔省HSP的临床,放射和遗传特征.
评估阿尔伯塔省不同族群中HSP的遗传变异性.

主要方法:

一项观察性研究在2012年至2021年期间招募了来自86个HSP家庭的100名患者.
基因检测是通过研究和/或临床实验室进行的,以确定致病变体.

主要成果:

在阿尔伯塔省,HSP的总体患病率为每10万人中2.3人,土著人口为每10万人中2.8人.
在17个基因 (SPAST,SPG7,SPG11,CAPN1,SACS最常见) 的56%的家族中发现了致病变体.
在白人 (54%),土著 (62.5%),亚洲 (50%) 和中东 (66.7%) 家庭中确认了基因诊断,在土著家庭中发现了独特的变异.

结论:

这项研究提供了阿尔伯塔省土著人口中HSP患病率和遗传原因的首次详细检查.
研究结果强调了在诊断和研究HSP表型和基因型时考虑种族多样性的重要性.

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...
