Lesch-Nyhan Syndrome

Lesch-Nyhan Syndrome
Lesch-Nyhan syndrome (LNS) is a rare, inherited disorder caused by a deficiency of the enzyme hypoxanthine-guanine phosphoribosyltransferase (HPRT). LNS is an X-linked recessive disease-- the gene is carried by the mother and passed on to her son.  Symptoms include severe gout, poor muscle control, and moderate intellectual disability, which appear in the first year of life.  A striking feature of LNS is self-mutilating behaviors

Higher Death Rate Among Youth with First Episode Psychosis

Image
High Mortality in First Episode Psychosis in Youth A new study shows that young people experiencing first episode psychosis have a much higher death rate than previously thought. Researchers analyzed data on approximately 5,000 individuals aged 16-30 with commercial health insurance who had received a new psychosis diagnosis, and followed them for the next 12 months. They found that the group had a mortality rate at least 24 times greater than the same age group in the general population, in the 12 months after the initial psychosis diagnosis.  continue reading......

News on Human Behavior: Brain Scans Could Help Doctors Better Predict Your Behavior

Image
 (CNN REPORT):  Forget horoscopes or fortune tellers. There's a new way to tell your future, and it involves a much more reliable medium: human neuroscience. A new study looks at over 70 scientific publications about brain scans such as functional magnetic resonance imaging or electroencephalography, noninvasive tests that measure brain activity. The paper that runs in the latest edition of Neuron concludes that doctors might have more success treating some patients if they examined the way a person's brain functioned first. Brain scans have been used to make basic discoveries about human behavior for decades, but they are not routinely ordered to determine someone's overall health or course of treatment in the way as blood test are used. This new study suggests technology in this area has become so advanced that approaches to treatment would be more effective if brain scans were used more routinely. For instance, when someone is being treated f...

Common Gene Variants Account for Most Genetic Risk for Autism: Roles of Heritability, Mutations, Environment Estimated – NIH-funded Study

Image
July 20, 2014 • NIH Press Release Most of the genetic risk for autism comes from versions of genes that are common in the population rather than from rare variants or spontaneous glitches, researchers funded by the National Institutes of Health have found. Heritability also outweighed other risk factors in this largest study of its kind to date. About 52 percent of the risk for autism was traced to common and rare inherited variation, with spontaneous mutations contributing a modest 2.6 percent of the total risk. “Genetic variation likely accounts for roughly 60 percent of the liability for autism, with common variants comprising the bulk of its genetic architecture,” explained Joseph Buxbaum, Ph.D.  , of the Icahn School of Medicine at Mount Sinai (ISMMS), New York City. “Although each exerts just a tiny effect individually, these common variations in the genetic code add up to substantial impact, taken together.” Buxbaum, and colleag...
