Changes in scores of genes contribute to autism risk — Newfound genetic differences provide many hints at causes – Small differences in as many as a thousand genes contribute to risk for autism or autism spectrum disorder (ASD). This new study examined data on several types of rare, genetic differences in more than 14,000 DNA samples from parents, affected children, and unrelated individuals.
Biomarker predicts effectiveness of brain cancer treatment – Researchers at the University of California, San Diego School of Medicine have identified a new biomarker that predicts whether glioblastoma – the most common form of primary brain cancer – will respond to chemotherapy.
New test predicts the risk of non-hereditary breast cancer — A simple blood test is currently in development that could help predict the likelihood of a woman developing breast cancer – A simple blood test is currently in development that could help predict the likelihood of a woman developing breast cancer, even in the absence of a high-risk BRCA1 gene mutation. This new research is published in the Genome Medicine.
How a versatile gut bacterium helps us get our daily dietary fiber – A common gut bacterium – Bacteroides ovatus – helps us metabolize a main component of dietary fibre xyloglucan from the cell walls of fruits and vegetables, revealed by researchers from University of British Columbia in the journal Nature.
FDA Orders Genetic Testing Firm 23andme to Stop Marketing DNA Analysis Service — Blocks Sale of a Company’s Mail-Order Gene Tests – The Food and Drug Administration, USA has ordered 23andme – the maker of a popular genetic-testing kit to stop sales of its heavily marketed product, saying the mail-order tests haven’t been proven effective and could dangerously mislead people about their health.
Meat, egg and dairy nutrient essential for brain development — Deficiency of asparagine synthetase caused by rare genetic disorder affects brain development – Asparagine, found in foods such as meat, eggs, and dairy products, was until now considered non-essential because it is produced naturally by the body. Researchers at the University of Montreal and its affiliated CHU Sainte-Justine Hospital found that the amino acid is essential for normal brain development.
DNA markers in low-IQ autism suggest heredity – Researchers are striving to understand the different genetic structures that underlie at least a subset of autism spectrum disorders. In cases where the genetic code is in error, did that happen anew in the patient, perhaps through mutation or copying error, or was it inherited? A new study in the American Journal of Human Genetics finds evidence that there may often be a recessive, inherited genetic contribution in autism with significant intellectual disability.
Ordinary skin cells morphed into functional brain cells — Scientists at CWRU School of Medicine discover new technique that holds promise for the treatment of multiple sclerosis and cerebral palsy – Researchers at Case Western Reserve School of Medicine have discovered a technique that directly converts skin cells to the type of brain cells destroyed in patients with multiple sclerosis, cerebral palsy and other so-called myelin disorders.
