Abstract

Amyotrophic lateral sclerosis (ALS), a complicated neurodegenerative disorder affected by hereditary and environmental variables, is a condition. In this study, the genetic makeup of ALS is investigated, with a focus on the SOD1 gene's single-nucleotide polymorphisms (SNPs) and their ability to affect disease risk. Eleven high-risk missense variations that may impair the functionality of the SOD1 protein were discovered after a thorough examination of SNPs in the SOD1 gene. These mutations were chosen using a variety of prediction approaches, highlighting their importance in the aetiology of ALS. Notably, it was discovered that the stability of the SOD1 wild-type protein structure was compromised by the G38R and G42D SOD1 variants. Additionally, Edaravone, a possible ALS medication, showed a greater affinity for binding mutant SOD1 structures, pointing to potential personalised treatment possibilities. The high-risk SNPs discovered in this investigation seem to have functional effects, especially on the stability of proteins and their interactions with other molecules. This study clarifies the complex genetics of ALS and offers insights into how these genetic variations may affect the effectiveness of therapeutic interventions, particularly in the context of edaravone. In this study advances our knowledge of the genetic mechanisms causing ALS vulnerability and prospective therapeutic strategies. Future studies are necessary to confirm these results and close the gap between individualised clinical applications and improved ALS care.

摘要

肌萎缩侧索硬化症(ALS)是一种受遗传和环境因素影响的复杂神经退行性疾病。在本研究中,对ALS的基因组成进行了研究,重点关注超氧化物歧化酶1(SOD1)基因的单核苷酸多态性(SNP)及其影响疾病风险的能力。在对SOD1基因中的SNP进行全面检查后,发现了11种可能损害SOD1蛋白功能的高风险错义变异。这些突变是通过多种预测方法筛选出来的,突出了它们在ALS病因学中的重要性。值得注意的是,发现G38R和G42D SOD1变体破坏了SOD1野生型蛋白结构的稳定性。此外,依达拉奉作为一种可能的ALS药物,对结合突变型SOD1结构表现出更高的亲和力,这表明了潜在的个性化治疗可能性。本研究中发现的高风险SNP似乎具有功能效应,特别是对蛋白质稳定性及其与其他分子相互作用的影响。这项研究阐明了ALS复杂的遗传学,并为这些基因变异如何影响治疗干预的有效性提供了见解,特别是在依达拉奉的背景下。本研究推进了我们对导致ALS易感性的遗传机制和潜在治疗策略的认识。未来的研究有必要证实这些结果,并缩小个性化临床应用与改善ALS护理之间的差距。
