Several genes involved in the pathogenesis have been identified, with the human leukocyte antigen (HLA) system playing an essential role. However, the relationship between HLA and a cluster of hematological diseases has received little attention in China. Blood samples (n = 123913) from 43568 patients and 80345 individuals without known pathology were genotyped for HLA class I and II using sequencing-based typing. We discovered that HLA-A11:01, B40:01, C01:02, DQB103:01, and DRB109:01 were prevalent in China. Furthermore, three high-frequency alleles (DQB103:01, DQB106:02, and DRB115:01) were found to be hazardous in malignant hematologic diseases when compared to controls. In addition, for benign hematologic disorders, 7 high-frequency risk alleles (A01:01, B46:01, C01:02, DQB103:03, DQB105:02, DRB109:01, and DRB114:54) and 8 high-frequency susceptible genotypes (A11:01-A11:01, B46:01-B58:01, B46:01-B46:01, C01:02-C03:04, DQB103:01-DQB105:02, DQB103:03-DQB106:01, DRB109:01-DRB115:01, and DRB114:54-DRB1*15:01) were observed. To summarize, our findings indicate the association between HLA alleles/genotypes and a variety of hematological disorders, which is critical for disease surveillance.
已鉴定出一些与发病机制相关的基因,其中人类白细胞抗原(HLA)系统起着至关重要的作用。然而,HLA 与一组血液系统疾病之间的关系在中国尚未得到充分关注。我们使用基于测序的分型方法对来自 43568 名患者和 80345 名无已知病理个体的 123913 份血液样本进行了 HLA Ⅰ类和Ⅱ类基因分型。我们发现 HLA-A11:01、B40:01、C01:02、DQB103:01 和 DRB109:01 在中国人中较为常见。此外,与对照组相比,在恶性血液病中发现三个高频等位基因(DQB103:01、DQB106:02 和 DRB115:01)具有危害性。此外,对于良性血液疾病,有 7 个高频风险等位基因(A01:01、B46:01、C01:02、DQB103:03、DQB105:02、DRB109:01 和 DRB114:54)和 8 个高频易感基因型(A11:01-A11:01、B46:01-B58:01、B46:01-B46:01、C01:02-C03:04、DQB103:01-DQB105:02、DQB103:03-DQB106:01、DRB109:01-DRB115:01 和 DRB114:54-DRB1*15:01)被观察到。总之,我们的研究结果表明 HLA 等位基因/基因型与多种血液系统疾病之间存在关联,这对于疾病监测至关重要。
