Clustered regularly interspaced short palindromic repeats (CRISPR) CRISPR-associated protein 9 (Cas9), including specific guide RNAs (gRNAs), can excise integrated human immunodeficiency virus type 1 (HIV-1) provirus from host chromosomes. To date, anti-HIV-1 gRNAs have been designed to account for off-target activity, however, they seldom account for genetic variation in the HIV-1 genome within and between patients, which will be crucial for therapeutic application of this technology. This analysis tests the ability of published anti-HIV-1 gRNAs to cleave publicly available patient-derived HIV-1 sequences to inform gRNA design and provides basic computational tools to researchers in the field.
成簇规律间隔短回文重复序列（CRISPR）相关蛋白 9（Cas9），包括特定的向导 RNA（gRNA），可以从宿主染色体中切除整合的人类免疫缺陷病毒 1 型（HIV-1）前病毒。迄今为止，已经设计了抗 HIV-1 的 gRNA 来考虑脱靶活性，但是，它们很少考虑到患者内和患者间 HIV-1 基因组的遗传变异，这对于该技术的治疗应用至关重要。该分析测试了已发表的抗 HIV-1 gRNA 切割公开可用的源自患者的 HIV-1 序列的能力，以为 gRNA 设计提供信息，并为该领域的研究人员提供基本的计算工具。
