Latest Heritability of autism Stories

A team of researchers from the University of California, San Diego School of Medicine and the Center for Cancer Systems Biology (CCSB) at the Dana-Farber Cancer Institute has uncovered a new aspect of autism, revealing that proteins involved in autism interact with many more partners than previously known. These interactions had not been detected earlier because they involve alternatively spliced forms of autism genes found in the brain. In their study, published in the April 11, 2014...

UCL scientists have shown that there are widespread differences in how genes, the basic building blocks of the human body, are expressed in men and women's brains. Based on post-mortem adult human brain and spinal cord samples from over 100 individuals, scientists at the UCL Institute of Neurology were able to study the expression of every gene in 12 brain regions. The results are published today in Nature Communications. They found that the way that the genes are expressed in the...

Study Find Cells Brain Regions Affected By Autism Gene Mutations
2013-11-22 09:42:02

redOrbit Staff & Wire Reports - Your Universe Online Researchers from Yale University and the University of California, San Francisco (UCSF) have pinpointed the types of cells and regions of the brain affected by the genetic mutations associated with autism. Their findings, which were reported in Thursday’s edition of the journal Cell, indicate that a common variety of neural circuits are affected by autism-risk genes. Furthermore, they determined how, when, where and in what...

Social Symptoms In Autistic Children Could Be Caused By Hyper-connected Neurons
2013-11-07 13:46:20

Cell Press The brains of children with autism show more connections than the brains of typically developing children do. What's more, the brains of individuals with the most severe social symptoms are also the most hyper-connected. The findings reported in two independent studies published in the Cell Press journal Cell Reports on November 7th are challenge the prevailing notion in the field that autistic brains are lacking in neural connections. The findings could lead to new treatment...

Rutgers University scientists also find strong evidence of a genetic connection in areas of social skills and repetitive behaviors Lorenzo Miodus-Santini an 11-year-old sixth-grader from Princeton, who was classified as autistic at only 13 months old, was never a big talker. As an infant he didn't babble or coo. When he was a toddler beginning to speak, he would learn one word but forget another. His older brother, Christian, a 15-year-old high school sophomore, shared some similar...

Recent US data indicate 78 percent rise in prevalence of autism among 8 year olds in 2004-08 The number of newly diagnosed cases of autism has leveled off in the UK after a five-fold surge during the 1990s, finds research published in the online journal BMJ Open. The findings differ from widely publicized results issued by the US Centers for Disease Control and Prevention (CDC) last year, which reported a 78% increase in the prevalence of the condition in eight year old children between...

Deletions may be linked to miswiring of brain neurons. New York, NY (PRWEB) October 03, 2013 Using powerful genetic sequencing technology, a team of investigators, led by researchers at the Icahn School of Medicine at Mount Sinai, scanned the genome of hundreds of individuals, and discovered those diagnosed with autism spectrum disorder (ASD) were more likely to have gene deletions than were people without the disorder. That means those individuals — seven percent of the study group...

Findings in bacteria, yeast, mice show how flawed transport gene contributes to the condition Researchers say it's clear that some cases of autism are hereditary, but have struggled to draw direct links between the condition and particular genes. Now a team at the Johns Hopkins University School of Medicine, Tel Aviv University and Technion-Israel Institute of Technology has devised a process for connecting a suspect gene to its function in autism. In a report in the Sept. 25 issue of...

Sometimes, when the DNA in a cell is copied during cell division, there is a mistake. A large portion of the genetic material could be duplicated or deleted. In each instance, there is often a greatly enhanced potential for serious genetic disease. Such changes are known as copy number variation (CNV) referring to the numbers of copies of a gene. Instead of ‘letters of the DNA alphabet’ being changed or missing, whole sentences, entire paragraphs or even pages/volumes of the encyclopedia...

The gene and protein responsible for causing Fragile X Syndrome emerges as a leading candidate in the search for the cause of autism and maybe even schizophrenia WALNUT CREEK, Calif., Aug. 21, 2013 /PRNewswire/ -- The little known FMR1 gene was first mapped in 1991. It was originally thought to cause only fragile X syndrome (FXS) when the gene mutates, but scientists have since discovered that the same mutation that causes the developmental and intellectual disabilities associated...
