Latest Heritability of autism Stories

Researchers at UCLA have found a possible explanation for why autistic children act and think differently than their peers. For the first time, they've shown that the connections between brain regions that are important for language and social skills grow much more slowly in boys with autism than in non-autistic children.   Reporting in the current online edition of the journal Human Brain Mapping, senior author Jennifer G. Levitt, a professor of psychiatry at the Semel Institute for...

Image 1 - Autistic Facial Characteristics Identified

Research is a step toward understanding cause of autism The face and brain develop in coordination, with each influencing the other, beginning in the embryo and continuing through adolescence. Now, University of Missouri researchers have found distinct differences between the facial characteristics of children with autism compared to those of typically developing children. This knowledge could help researchers understand the origins of autism. "There is no clear answer about whether...

Finding may lead to screening test to identify susceptibility to having an autistic child A study by researchers at UC Davis has found that pregnant women with a particular gene variation are more likely to produce autoantibodies to the brains of their developing fetuses and that the children of these mothers are at greater risk of later being diagnosed with autism. The finding is the first to demonstrate a genetic mechanism at play in the development of the neurodevelopmental disorder...

Low Birth Weight Ups Risk Of Autism

University of Pennsylvania School of Nursing researchers have found a link between low birth weight and children diagnosed with autism. The researchers found that premature infants are five times more likely to have autism than children born at normal weight. The 862 children in the study were followed for 21 years after being born with a maximum birth weight of 4.4 pounds in New Jersey from September 1984 through July 1987. "As survival of the smallest and most immature babies...

(Ivanhoe Newswire) — Autism is one of the most common genetic alterations, caused by a deletion of the 27-gene cluster on chromosome 16. By generating mouse models of autism, scientists at Cold Spring Harbor Laboratory (CSHL) provided the first evidence that inheriting fewer copies of these genes leads to features resembling those used to diagnose children with autism. "Children normally inherit one copy of a gene from each parent. We had the tools to see whether copy number changes...

Evidence Found For Genetic Basis Of Autism

[ Watch the Video ] Models of autism show that gene copy number controls brain structure and behavior Scientists at Cold Spring Harbor Laboratory (CSHL) have discovered that one of the most common genetic alterations in autism -- deletion of a 27-gene cluster on chromosome 16 -- causes autism-like features. By generating mouse models of autism using a technique known as chromosome engineering, CSHL Professor Alea Mills and colleagues provide the first functional evidence that inheriting...

By Alicia Rose DelGallo, Ivanhoe Health Correspondent (Ivanhoe Newswire) -- Mice with a single defective gene are showing striking parallels to humans with autism. According to a study published in the September 30th issue of Cell, a Cell Press publication, the mouse model offers several promising discoveries. The study involved developing mice lacking CNTNAP2, a rare variant of the gene that has been shown to cause a form of autism known as cortical dysplasia-focal epilepsy syndrome...

Mice with a defective version of a single gene show behaviors and symptoms that are remarkably similar to characteristics observed in humans with autism spectrum disorders. The animals also respond similarly to an FDA-approved drug used to treat repetitive behaviors in people with autism. According to researchers who report their findings in the September 30th issue of Cell, a Cell Press publication, the mouse model offers a window into the biological mechanisms that underlie the disease...

These changes may also affect the mix of bacteria present in the digestive tract Researchers at the Center for Infection and Immunity (CII) at Columbia University's Mailman School of Public Health and at the Harvard Medical School report that children with autism and gastrointestinal disturbances have altered expression of genes involved in digestion. These variations may contribute to changes in the types of bacteria in their intestines. Full study findings are reported online in the...

The first transgenic mouse model of a rare and severe type of autism called Timothy Syndrome is improving the scientific understanding of autism spectrum disorder in general and may help researchers design more targeted interventions and treatments. The research is described in a paper published last week by scientists at the University at Buffalo and Stanford University in the Proceedings of the National Academy of Sciences. The transgenic mouse developed at UB exhibits the repetitive...
