Scientists Identify Six Novel Genes

Scientists identify six novel genes linked to cancer risk


Scientists at deCODE genetics/Amgen, and their collaborators have discovered six novel genes with rare germline variants that associate with cancer risk. The findings are published today in Nature Genetics under the title "Gene-based burden tests of rare germline variants identify six cancer susceptibility genes."

A subset of cancers arises in individuals who are born with rare sequence variants that significantly alter their cancer risk. The discovery of such variants, like those in the BRCA1- and BRCA2 genes, has led to improved early cancer detection and the development of targeted therapies, ultimately reducing the cancer burden and improving prognosis of those carrying these mutations.

In this study, the scientists analyzed three large genetic datasets from individuals of European descent, including 130,991 cancer patients and 733,486 controls.

Through a gene-based burden association analysis across 22 different cancer types, they found four novel genes associated with a risk of developing cancer; the pro-apoptotic BIK for prostate cancer, the autophagy involved ATG12 for colorectal cancer, TG for thyroid cancer, and CMTR2 for both lung cancer and cutaneous melanoma.

The relative increase in cancer risk conferred by these variants was substantial (90%–295%), but it should be noted that the design of the study does not allow accurate assessment of absolute lifetime cancer risk.

Additionally, the researchers found the first genes with rare variants that are associated with a decreased risk of cancer. Specifically, loss of AURKB was found to protect against any cancer type, and loss of PPP1R15A was associated with a 53% lower risk of breast cancer. This suggests that inhibition of PPP1R15A may be a therapeutic option for breast cancer.

The study revealed new insight into the biological mechanisms involved in cancer predisposition that will hopefully lead to better screening and treatment strategies.

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...

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 ...

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-...
