Disease

Diseases of Genetics and Genomics 


A disease is a particular abnormal condition that adversely affects the structure or function of all or part of an organism and is not immediately due to any external injury.[1] Diseases are often known to be medical conditions that are associated with specific signs and symptoms. A disease may be caused by external factors such as pathogens or by internal dysfunctions. For example, internal dysfunctions of the immune system can produce a variety of different diseases, including various forms of immunodeficiency, hypersensitivity, allergies, and autoimmune disorders.

In humans, disease is often used more broadly to refer to any condition that causes pain, dysfunction, distress, social problems, or death to the person affected, or similar problems for those in contact with the person. In this broader sense, it sometimes includes injuries, disabilities, disorders, syndromes, infections, isolated symptoms, deviant behaviors, and atypical variations of structure and function, while in other contexts and for other purposes these may be considered distinguishable categories. Diseases can affect people not only physically but also mentally, as contracting and living with a disease can alter the affected person's perspective on life.Death due to disease is called death by natural causes. 

There are four main types of disease: infectious diseases, deficiency diseases, hereditary diseases (including both genetic and non-genetic hereditary diseases), and physiological diseases. Diseases can also be classified in other ways, such as communicable versus non-communicable diseases. The deadliest diseases in humans are coronary artery disease (blood flow obstruction), followed by cerebrovascular disease and lower respiratory infections.[2] In developed countries, the diseases that cause the most sickness overall are neuropsychiatric conditions, such as depression and anxiety. Pathology, the study of disease, includes etiology, or the study of cause.

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 ...

Post-Stroke Cardiovascular risks

Study finds genetic factors key to post-stroke cardiovascular risks In a recent study published in the journal Stroke , researchers identify genetic and molecular risk factors for subsequent cardiovascular outcomes after incident stroke in an effort to identify potential therapeutic targets to improve patient prognoses. Identifying the causes of stroke Stroke is a major global health issue that causes significant disability and mortality, particularly arterial ischemic stroke (AIS). AIS, which is a type of stroke caused by blocked blood flow to the brain, is responsible for up to 85% of stroke cases. AIS arises due to cerebral blood vessel blockage, with modifiable risk factors including hypertension, diabetes, dyslipidemia, atrial fibrillation, obesity, and lifestyle behaviors. Although genome-wide association studies (GWAS) often focus on incident strokes, studying subsequent events can provide new insights into stroke progression. Further research is crucial to identify genetic and...

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...
