Genomics is one of the newest branches of biology that has progressed tremendously during the last decades. Genomics deals with the molecular structures, functions, evolution, and mapping of the genomes of any species and has signi fi cantly generated new information that has improved our understanding of the complex biology and genetic mechanisms of animal production systems. The advancement of genomics is linked with a number of key developments, which include the rapid expansion of next-generation sequencing and chip- based genotyping assays. Large-scale genomics data are now utilized more and more due to the dwindling cost of such sequencing and genotyping techniques. Livestock breeding programs, including selection and conservation efforts, have attained huge success due to affordable genomic prediction, particularly in dairy cattle. It is expected that there will be further reduction in the cost of these high-throughput genomic data generation platforms and more development of precise estimation methodologies. Multi-disciplinary involvement is going to further bene fi t the genomics community with the advancement of robust and reliable tools in the fi eld of bioinformatics and their use in livestock breeding. Keeping these developments in the area of livestock genomics in mind, the present Research topic of the Frontiers in Genetics titled “ Application of Genomics in Livestock Populations under Selection or Conservation ” was aptly selected with several major themes that highlighted the usage of genomics for conservation, current methods of genomics, application of whole-genome- and genome-wide-based techniques, and use of different bioinformatics tools and pipelines for the processing of genomic data. The resulting efforts contributed to the publication of a total 19 research papers in the current volume, comprising major focal points in the area of genomics of livestock and other species with the concerns of the present day. However, the ocean of genomics is too vast, and even this wide-array of published articles could hardly justify an ounce of that vastness! Nonetheless, genuine efforts were made to include articles in this volume on those central themes of genomics that comprise the major skills and techniques employed in various animal populations for selection and conservation issues. These include genome- wide association studies (GWAS), differential gene expression utilizing transcriptome data, and analysis of selection signatures through whole-genome sequencing and high-density genotyping datasets, which are utilized for discovering genes and genomic variants that control signi fi cant traits of importance in livestock species.

高通量基因分型能够对种群基因组学和全基因组关联研究中的遗传多样性进行大规模分析,这些研究结合了大量加入的基因型和表型表征。基于测序的基因分型方法由于较低的确定性偏差而逐渐替换传统的基因分型方法。然而,基于测序的全基因分型在具有较大基因组和高比例的重复性DNA的物种中变得昂贵。在这里,我们描述了CRISPR-CAS9技术在3.76-Gb基因组(镜头Culinaris)中耗尽重复元素,84%由重复序列组成,从而将测序数据集中在编码和调节区域(单子拷贝区域)上。我们设计了一组566,766个GRNA,旨在重复2.9英镑,排除了基于ATACSQ数据的重复区域重复的注释基因和推定的调节元素。新颖的耗竭方法去除了〜40%的读取映射到重复序列,从而将这些映射到单拷贝区域增加了约2.6倍。在分析2500万个片段时,与非部位的文库相比,测序数据中的重复对单个拷贝偏移增加了约10倍。在相同的条件下,我们还能够鉴定单拷贝区域中的遗传变异量增加了12倍,并通过挽救杂合变体的特征来提高基因分型精度,否则由于覆盖范围较低,否则会遗漏这些变体。该方法的执行方式类似,无论多路复用水平,文库类型或基因型,包括不同的品种和密切相关的物种(L. Orientalis)。我们的结果表明,CRISPR-CAS9驱动的重复耗竭将测序数据集中在单拷贝区域上,从而改善了大型和重复的基因组中的高密度和全基因组基因分型。

罗克维尔,马里兰州- 2024年7月22日 - 全球全球分子诊断专业社会的分子病理学协会(AMP)今天发表了共识建议,以帮助设计和验证临床DPYD基因分型测定,促进对不同实验室的测试标准化,并改善患者护理。手稿,“ DPYD基因分型建议:美国医学遗传学与基因组学院(ACMG),美国病理学家(CPIC)的临床药物遗传学实施联盟(CPIC)的联合共识建议(ESPT),药物基因组学知识库(PharmGKB®)和药物变异财团(PharmVar),”在《分子诊断杂志》发表之前在线发布。建立了AMP临床实践委员会的药物基因组学(PGX)工作组,以定义推荐用于临床测试的药物遗传学等位基因的关键属性,以及应包含在临床PGX基因分型测定中的最低变体。新的DPYD报告是AMP PGX工作组开发的一系列建议中的最新报告,旨在帮助标准化常用基因分型测定法的临床测试。它基于对CYP3A4 / CYP3A5,TPMT / NUDT15,CYP2D6的早期临床基因分型建议,对于华法林测试,CYP2C9和CYP2C19重要的基因。可选变体的第2层列表符合至少一个但不是全部标准的列表。对于医疗保健提供者而言,重要的是要实施这些建议以及其他相关的临床准则,例如CPIC和DPWG发布的建议,这两者主要着重于解释PGX测试结果并为特定药物对的治疗建议提供治疗建议。“Testing for variants in the DPYD gene can help identify individuals who may be at increased risk for severe fluoropyrimidine-related toxicity,” said Victoria M. Pratt, PhD, Co-Chair of the AMP PGx Working Group, Director of the Scientific Affairs for Pharmacogenetics at Agena Bioscience, and Adjunct Professor of Clinical Pharmacology at Indiana University School of Medicine.“这份新报告旨在改善临床实验室的临床实践,并促进临床实验室的标准化,并确保将适当的变体包括在临床PGX DPYD分析中。”与以前的临床PGX基因分型测定建议一样,AMP PGX工作组使用了建议包含的变体的两层分类。之所以选择,是因为它们对蛋白质和/或基因表达的功能活性具有良好的特征性作用,在人群/祖先组中具有明显的次要等位基因频率,具有可用的参考材料,可用于测定验证,并且对于使用标准分子测试方法进行疑问的临床实验室在技术上是可行的。 这些有关临床基因分型测定的建议不包括对蛋白质功能或基因表达不明的变体。 它们是作为参考指南而不是限制性列表。,是因为它们对蛋白质和/或基因表达的功能活性具有良好的特征性作用,在人群/祖先组中具有明显的次要等位基因频率,具有可用的参考材料,可用于测定验证,并且对于使用标准分子测试方法进行疑问的临床实验室在技术上是可行的。这些有关临床基因分型测定的建议不包括对蛋白质功能或基因表达不明的变体。它们是作为参考指南而不是限制性列表。
