Due to rapid mutations in the coronavirus genome over time and re-emergence of multiple novel variants of concerns (VOC), there is a continuous need for a periodic genome sequencing of SARS-CoV-2 genotypes of particular region. This is for on-time development of diagnostics, monitoring and therapeutic tools against virus in the global pandemics condition. Toward this goal, we have generated 18 high-quality whole-genome sequence data from 32 SARS-CoV-2 genotypes of PCR-positive COVID-19 patients, sampled from the Tashkent region of Uzbekistan. The nucleotide polymorphisms in the sequenced sample genomes were determined, including nonsynonymous (missense) and synonymous mutations in coding regions of coronavirus genome. Phylogenetic analysis grouped fourteen whole genome sample sequences (1, 2, 4, 5, 8, 10-15, 17, 32) into the G clade (or GR sub-clade) and four whole genome sample sequences (3, 6, 25, 27) into the S clade. A total of 128 mutations were identified, consisting of 45 shared and 83 unique mutations. Collectively, nucleotide changes represented one unique frameshift mutation, four upstream region mutations, six downstream region mutations, 50 synonymous mutations, and 67 missense mutations. The sequence data, presented herein, is the first coronavirus genomic sequence data from the Republic of Uzbekistan, which should contribute to enrich the global coronavirus sequence database, helping in future comparative studies. More importantly, the sequenced genomic data of coronavirus genotypes of this study should be useful for comparisons, diagnostics, monitoring, and therapeutics of COVID-19 disease in local and regional levels.
由于冠状病毒基因组随时间的快速突变以及多个新出现的关注变种(VOC),因此需要定期对特定地区的 SARS-CoV-2 基因型进行基因组测序。这是为了在全球大流行的情况下及时开发针对病毒的诊断、监测和治疗工具。为了实现这一目标,我们从乌兹别克斯坦塔什干地区的 32 例 PCR 阳性 COVID-19 患者中生成了 18 条高质量的全基因组序列数据。确定了测序样本基因组中的核苷酸多态性,包括冠状病毒基因组编码区中的非同义(错义)和同义突变。系统进化分析将 14 条全基因组样本序列(1、2、4、5、8、10-15、17、32)分为 G 分支(或 GR 亚分支),4 条全基因组样本序列(3、6、25、27)分为 S 分支。共鉴定出 128 个突变,包括 45 个共享突变和 83 个独特突变。总的来说,核苷酸变化代表一个独特的移码突变、4 个上游区突变、6 个下游区突变、50 个同义突变和 67 个错义突变。本研究提供的序列数据是乌兹别克斯坦共和国的第一个冠状病毒基因组序列数据,应该有助于丰富全球冠状病毒序列数据库,有助于未来的比较研究。更重要的是,本研究冠状病毒基因型的测序基因组数据应有助于在本地和地区层面比较、诊断、监测和治疗 COVID-19 疾病。
