Quantitative Trait Loci (QTL)

Quantitative Trait Loci (QTL)

Quantitative Trait Loci (QTL) are specific regions of the genome that are associated with the variation of quantitative traits—traits that are influenced by multiple genes and environmental factors. Unlike simple Mendelian traits controlled by a single gene, quantitative traits such as height, yield, disease resistance, or body weight are governed by many genetic loci that each contribute small effects. QTL analysis helps researchers identify genomic regions linked to these complex traits through statistical associations between genetic markers and phenotypic variation. This approach is widely used in plant and animal breeding, evolutionary biology, and medical genetics to understand genetic architecture and improve desirable traits through marker-assisted selection and genomic selection.

Genetic factors with clinical trial stoppage

Genetic factors associated with reasons for clinical trial stoppage Many drug discovery projects are started but few progress fully through clinical trials to approval. Previous work has shown that human genetics support for the therapeutic hypothesis increases the chance of trial progression. Here, we applied natural language processing to classify the free-text reasons for 28,561 clinical trials that stopped before their endpoints were met. We then evaluated these classes in light of the underlying evidence for the therapeutic hypothesis and target properties. We found that trials are more likely to stop because of a lack of efficacy in the absence of strong genetic evidence from human populations or genetically modified animal models. Furthermore, certain trials are more likely to stop for safety reasons if the drug target gene is highly constrained in human populations and if the gene is broadly expressed across tissues. These results support the growing use of human genetics to ...

Fruitful innovation

Fruitful innovation: Transforming watermelon genetics with advanced base editors The development of new adenine base editors (ABE) and adenine-to-thymine/ guanine base editors (AKBE) is transforming watermelon genetic engineering. These innovative tools enable precise A:T-to-G and A:T-to-T base substitutions, allowing for targeted genetic modifications. The research highlights the efficiency of these editors in generating specific mutations, such as a flowerless phenotype in ClFT (Y84H) mutant plants. This advancement not only enhances the understanding of gene function but also significantly improves molecular breeding, paving the way for more efficient watermelon crop improvement. Traditional breeding methods for watermelon often face challenges in achieving desired genetic traits efficiently and accurately. While CRISPR/Cas9 has provided a powerful tool for genome editing, its precision and scope are sometimes limited. These limitations highlight the need for more advanced gene-e...

Genetics study on COVID-19

Large genetic study on severe COVID-19 Bonn researchers confirm three other genes for increased risk in addition to the known TLR7 gene Whether or not a person becomes seriously ill with COVID-19 depends, among other things, on genetic factors. With this in mind, researchers from the University Hospital Bonn (UKB) and the University of Bonn, in cooperation with other research teams from Germany, the Netherlands, Spain and Italy, investigated a particularly large group of affected individuals. They confirmed the central and already known role of the TLR7 gene in severe courses of the disease in men, but were also able to find evidence for a contribution of the gene in women. In addition, they were able to show that genetic changes in three other genes of the innate immune system contribute to severe COVID-19. The results have now been published in the journal " Human Genetics and Genomics Advances ". Even though the number of severe cases following infection with the SARS-CoV-...
