Many common and rare variants associated with hematologic traits have been discovered through imputation on large-scale reference panels. However, the majority of genome-wide association studies (GWASs) have been conducted in Europeans, and determining causal variants has proved challenging. We performed a GWAS of total leukocyte, neutrophil, lymphocyte, monocyte, eosinophil, and basophil counts generated from 109,563,748 variants in the autosomes and the X chromosome in the Trans-Omics for Precision Medicine (TOPMed) program, which included data from 61,802 individuals of diverse ancestry. We discovered and replicated 7 leukocyte trait associations, including (1) the association between a chromosome X, pseudo-autosomal region (PAR), noncoding variant located between cytokine receptor genes (CSF2RA and CLRF2) and lower eosinophil count; and (2) associations between single variants found predominantly among African Americans at the S1PR3 (9q22.1) and HBB (11p15.4) loci and monocyte and lymphocyte counts, respectively. We further provide evidence indicating that the newly discovered eosinophil-lowering chromosome X PAR variant might be associated with reduced susceptibility to common allergic diseases such as atopic dermatitis and asthma. Additionally, we found a burden of very rare FLT3 (13q12.2) variants associated with monocyte counts. Together, these results emphasize the utility of whole-genome sequencing in diverse samples in identifying associations missed by European-ancestry-driven GWASs.

不同受试者的全基因组测序确定了白细胞特征的遗传相关性:NHLBI TOPMed 程序

许多与血液学特征相关的常见和罕见变异已通过对大规模参考面板的插补发现。然而,大多数全基因组关联研究 (GWAS) 都是在欧洲人中进行的,确定因果变异已被证明具有挑战性。我们对精准医学跨组学 (TOPMed) 计划中常染色体和 X 染色体中的 109,563,748 个变异生成的总白细胞、中性粒细胞、淋巴细胞、单核细胞、嗜酸性粒细胞和嗜碱性粒细胞计数进行了 GWAS,其中包括来自 61,802 个个体的数据不同的血统。我们发现并复制了 7 种白细胞性状关联,包括 (1) X 染色体、拟常染色体区域 (PAR)、位于细胞因子受体基因 ( CSF2RACLRF2)和较低的嗜酸性粒细胞计数;(2) 主要在S1PR3 (9q22.1) 和HBB (11p15.4) 位点以及单核细胞和淋巴细胞计数的非裔美国人中发现的单一变异之间的关联。我们进一步提供的证据表明,新发现的嗜酸性粒细胞降低染色体 X PAR 变异可能与特应性皮炎和哮喘等常见过敏性疾病的易感性降低有关。此外,我们发现了与单核细胞计数相关的非常罕见的FLT3 (13q12.2) 变体的负担。总之,这些结果强调了不同样本中全基因组测序在识别欧洲血统驱动的 GWAS 遗漏的关联方面的效用。
