项目摘要

ABSTRACT Diffuse large B cell lymphoma (DLBCL) is the most common form of blood cancer and is characterized by a striking degree of genetic heterogeneity. It has been known for some time that African American patients have poorer outcomes than Caucasian patients. After correcting for potential differences in socioeconomics and access to care, our data indicate that the poorer outcomes in African Americans arise primarily from distinct genetics of their tumors. The underlying genetic causes of these poorer outcomes have not been studied systematically. Here, we propose to investigate tumor and germline genetics of African Americans to comprehensively understand the genetic basis of their poorer outcomes. Preliminary genomic analysis of African American DLBCL patients has revealed more frequent mutations in histone methyltransferase genes and other genes. In this proposal, we seek to comprehensively define the genetic origins of poor outcomes in African Americans with DLBCL and perform functional characterization of selected genomic alterations.

摘要弥漫性大B细胞淋巴瘤（DLBCL）是最常见的血癌形式，其特征在于：遗传异质性的显著程度。据了解，一段时间以来，非洲裔美国患者结果比白人患者差。在修正了社会经济和获得护理，我们的数据表明，非洲裔美国人的不良结果主要来自不同的肿瘤的遗传学。这些较差结果的潜在遗传原因尚未研究系统地在这里，我们建议调查非裔美国人的肿瘤和生殖系遗传学，全面了解他们较差结果的遗传基础。初步基因组分析非裔美国人DLBCL患者揭示了组蛋白甲基转移酶基因更频繁的突变和其他基因。在这项提案中，我们试图全面定义不良结果的遗传起源，患有DLBCL的非裔美国人，并对选定的基因组改变进行功能表征。
