Amyotrophic lateral sclerosis (ALS) and Alzheimer's disease (AD) patients show a higher prevalence of Lewy body disease than the general population. Additionally, parkinsonian features were found in about 30% of ALS patients. We aimed to explore the frequency of Parkinson's disease (PD)-causative genes in ALS patients, compared to AD and healthy controls (HCs). We used next-generation sequencing multigene panels by analyzing , , , , , , , , , , and genes. gene, a risk factor for PD, was also analyzed. In total, 130 ALS and 100 AD patients were investigated. PD-related genes were found to be altered in 26.2% of ALS, 20% of AD patients and 19.2% of HCs. Autosomal recessive genes were significantly more involved in ALS as compared to AD and HCs ( = 0.021). variants were more frequent in ALS than in AD and HCs, although not significantly. However, the p.Arg402Cys variant was increased in ALS than in HCs ( = 0.025). This finding is consistent with current literature, as parkin levels were found to be decreased in ALS animal models and patients. Our results confirm the possible role of PD-related genes as risk modifier in ALS pathogenesis.
肌萎缩侧索硬化症(ALS)和阿尔茨海默病(AD)患者的路易体病患病率高于普通人群。此外,约 30%的 ALS 患者存在帕金森特征。我们旨在探讨与 AD 和健康对照(HC)相比,帕金森病(PD)相关基因在 ALS 患者中的频率。我们使用下一代测序多基因面板分析了 、 、 、 、 、 、 、 、 、 、 和 基因。还分析了 PD 风险因素 基因。总共调查了 130 名 ALS 和 100 名 AD 患者。PD 相关基因在 26.2%的 ALS、20%的 AD 患者和 19.2%的 HCs 中发生改变。与 AD 和 HCs 相比,常染色体隐性基因在 ALS 中明显更为常见(=0.021)。与 AD 和 HCs 相比,ALS 中 变体更为常见,尽管差异无统计学意义。然而,p.Arg402Cys 变体在 ALS 中比在 HCs 中更为常见(=0.025)。这一发现与当前的文献一致,因为在 ALS 动物模型和患者中发现 parkin 水平降低。我们的结果证实了 PD 相关基因作为 ALS 发病机制中风险修饰因子的可能作用。
