To elucidate the genetic architecture of amyotrophic lateral sclerosis (ALS) and find associated loci, we assembled a custom imputation reference panel from whole-genome-sequenced patients with ALS and matched controls (n = 1,861). Through imputation and mixed-model association analysis in 12,577 cases and 23,475 controls, combined with 2,579 cases and 2,767 controls in an independent replication cohort, we fine-mapped a new risk locus on chromosome 21 and identified C21orf2 as a gene associated with ALS risk. In addition, we identified MOBP and SCFD1 as new associated risk loci. We established evidence of ALS being a complex genetic trait with a polygenic architecture. Furthermore, we estimated the SNP-based heritability at 8.5%, with a distinct and important role for low-frequency variants (frequency 1-10%). This study motivates the interrogation of larger samples with full genome coverage to identify rare causal variants that underpin ALS risk.
为了阐明肌萎缩侧索硬化症（ALS）的遗传结构并找到相关基因座，我们从全基因组测序的ALS患者及匹配的对照（n = 1,861）中组装了一个定制的归因参考面板。通过对12,577例病例和23,475例对照进行归因和混合模型关联分析，并结合一个独立重复队列中的2,579例病例和2,767例对照，我们在21号染色体上精细定位了一个新的风险基因座，并确定C21orf2为与ALS风险相关的基因。此外，我们将MOBP和SCFD1鉴定为新的相关风险基因座。我们证实了ALS是一种具有多基因结构的复杂遗传性状。此外，我们估计基于单核苷酸多态性（SNP）的遗传率为8.5%，低频变异（频率为1-10%）具有独特且重要的作用。这项研究促使人们对具有全基因组覆盖的更大样本进行研究，以识别构成ALS风险基础的罕见因果变异。
