Schizophrenia not a single disease but multiple genetically distinct disorders

Schizophrenia not a single disease but multiple genetically distinct disorders
New research shows that schizophrenia isn’t a single disease but a group of eight genetically distinct disorders, each with its own set of symptoms. The finding could be a first step toward improved diagnosis and treatment for the debilitating psychiatric illness. The research at Washington University School of Medicine in St. Louis is reported online Sept. 15 in The American Journal of Psychiatry. About 80 percent of the risk for schizophrenia is known to be inherited, but scientists have struggled to identify specific genes for the condition. Now, in a novel approach analyzing genetic influences on more than 4,000 people with schizophrenia, the research team has identified distinct gene clusters that contribute to eight different classes of schizophrenia. “Genes don’t operate by themselves,” said C. Robert Boston Igor Zwir, PhD, one of the senior investigators, helped match precise DNA variations in people with and without schizophrenia to symptoms in individual patients.

Height differences 'could be caused by DNA changes' 5 October 2014Last updated at 13:57 ET Thousands of genes could be involved in height, according to the study Subtle changes in our genetic make-up could help to explain why some people are taller than others, the largest ever study of height has suggested. About 400 genome regions have been identified that may be responsible for the extra inches, according to research involving more than 250,000 people.

Spirulina: The Amazing Super Food You've Never Heard of Imagine a plant that can nourish your body by providing most of the protein you need to live, help prevent the annoying sniffling and sneezing of allergies, reinforce your immune system, help you control high blood pressure and cholesterol, and help protect you from cancer. Does such a "super food" exist?Yes. It's called spirulina.Unlike plants you may grow in your garden, this "miracle" plant is a form of blue-green algae that springs from warm, fresh water bodies.

Schizophrenia What is schizophrenia? Schizophrenia is a chronic, severe, and disabling brain disorder that has affected people throughout history. About 1 percent of Americans have this illness.1 People with the disorder may hear voices other people don't hear. They may believe other people are reading their minds, controlling their thoughts, or plotting to harm them. This can terrify people with the illness and make them withdrawn or extremely agitated. Doctors 3D-print 'living' body parts Image copyright Wake Forest Custom-made, living body parts have been 3D-printed in a significant advance for regenerative medicine, say scientists. The sections of bone, muscle and cartilage all functioned normally when implanted into animals. The breakthrough, published in Nature Biotechnology, raises the hope of using living tissues to repair the body. Experts described the technology, developed in the US, as a "goose that really does lay golden eggs". The idea of placing individual human cells in a precise pattern to replace a damaged jaw, missing ear or scarred heart muscle holds much promise.

Schizophrenia - Statistics on Recovery Home DNA Learning Center Preparing students and families to thrive in the gene age Website Search Sperm carries information about dad's weight Turns out dads are also eating for two. A study published December 3 in Cell Metabolism reveals that a man's weight affects the heritable information contained in sperm. The sperm cells of lean and obese men possess different epigenetic marks, notable at gene regions associated with the control of appetite. The comparisons, which included 13 lean men and 10 obese men, offer one biological explanation for why children of obese fathers are themselves more predisposed to obesity. In the next phase of the study, the investigators tracked 6 men undergoing weight-loss surgery to see how it affected their sperm.
