Diagnosing Disease Conditions by Analyzing Plasma Protein Expression Patterns

 A proof-of-concept study demonstrated that protein expression patterns in plasma samples were indicative of many different health issues, and that combining large-scale protein scanning with machine learning was a viable approach for the development of new diagnostic and prognostic tools. More...

Genetic Architectures of Schizophrenia Compared in Different Populations

 While the common genetic variants contributing to schizophrenia in East Asian individuals appear to broadly resemble those found in Europeans, polygenic risk scores (PRS) for the condition cannot necessarily be transferred from one population to the next. More...

Marker Panel Detects Early Liver Cancer with Increased Sensitivity

 Several types of cancer can form in the liver. The most common type of liver cancer is hepatocellular carcinoma, which begins in the main type of liver cell (hepatocyte). Other types of liver cancer, such as intrahepatic cholangiocarcinoma and hepatoblastoma, are much less common. More...

Rare Genetic Variants Associated with Sudden Cardiac Death

 A recent study has assessed the prevalence of rare pathogenic variants in sudden cardiac death cases versus controls, and the prevalence and clinical importance of such mutations in an asymptomatic adult population. More...
