Abstract

X chromosome-wide association studies (XWAS) have identified susceptibility variants for various neurodegenerative and neurodevelopmental diseases. The unique characteristics of the chromosome require more complex analytical approaches than standard genome-wide association studies. Over the past 2 decades, refined XWAS methods have better accounted for this biology. Given that many neurological diseases show sex-biased prevalence, XWAS offers a valuable framework for investigating sex-specific genetic contributions. This review summarizes published neurological XWAS ( = 10), highlighting methodological approaches. Despite the challenges of genetic analyses for the X chromosome, XWAS remains a key approach for studying its role in disease mechanisms.

摘要

X染色体全基因组关联研究（XWAS）已经确定了多种神经退行性疾病和神经发育疾病的易感性变异。与标准的全基因组关联研究相比，该染色体的独特特征需要更复杂的分析方法。在过去20年中，改进后的XWAS方法更好地考虑了这种生物学特性。鉴于许多神经系统疾病存在性别差异患病率，XWAS为研究性别特异性遗传贡献提供了一个有价值的框架。本综述总结了已发表的神经学XWAS（n = 10），突出了方法学途径。尽管对X染色体进行遗传分析存在挑战，但XWAS仍然是研究其在疾病机制中作用的关键方法。
