Autism has a strong genetic basis, but so far efforts to identify the responsible genes have had mixed results. The reason for this is that autism is influenced by many different genes, and different genes are involved in different individuals, making it hard to find the common genetic ground between patients. Now, research conducted at the Hebrew University of Jerusalem has shown that despite this fact, the different genes involved in autism tend to be involved in specific processes in...

Progress Being Made In Autism Research

Connie K. Ho for RedOrbit.com Out of four million children born each year in the United States, 400,000 to 600,000 are born with neurodevelopmental disorders - including autism. With this alarming rate, there has been an increase in the amount of research done to examine the disorder.  Recent studies by a number of institutions have made progress in understanding autism as an illness. To begin, an editorial that was recently published by the Mount Sinai Medical Center in the...

A team led by scientists at Cold Spring Harbor Laboratory (CSHL) publishes research today indicating a striking association between genes found disrupted in children with autism and genes that are targets of FMRP, the protein generated by the gene FMR1, whose dysfunction causes Fragile-X syndrome. The new study appears online April 25 in the journal Neuron. Fragile-X syndrome is the most common cause of inherited intellectual disability. It is also counted among the autism spectrum...

A new study, published by Cell Press in the April 26 issue of the journal Neuron, discovers several genes associated with autism and finds evidence for a shared genetic mechanism underlying autism and fragile X syndrome, the most common genetic cause of intellectual disability. It is well established that genetic variation caused by mutation can lead to autism spectrum disorders, and research has repeatedly implicated "de novo" (new) mutations, those that show up for the first time in...

When a child has autism, siblings are also at risk for the disorder. New research from Washington University School of Medicine in St. Louis shows that the genetic reach of the disorder often extends to half siblings as well. On the surface, the finding may not be surprising – half siblings share about 25 percent of their genes. But the discovery is giving scientists new clues to how autism is inherited. According to principal investigator John N. Constantino, MD, the new research...

New technique reveals another piece of spectrum's genetic architecture There is little argument among experts that autism spectrum disorders (ASD), complex developmental disabilities that vary widely in their severity, are caused by both genetic and environmental factors. Advances in genome sequencing now permit scientists to uncover specific mutations in DNA that are associated with ASD at unprecedented resolution. Such data are vital to understanding the genetic basis of the disorder....

Non-inherited mutations spotlight role of environment — NIH-supported study, consortium Researchers have turned up a new clue to the workings of a possible environmental factor in autism spectrum disorders (ASDs): fathers were four times more likely than mothers to transmit tiny, spontaneous mutations to their children with the disorders. Moreover, the number of such transmitted genetic glitches increased with paternal age. The discovery may help to explain earlier evidence linking...

New Research Links Gene Mutations To Autism
2012-04-05 05:04:52

Researchers reported in the journal Nature on Wednesday that about 15 percent of autism cases in families with a single autistic child are associated with spontaneous mutations that occur in six cells. Several papers published in the April 4 issue of the journal show how gene mutations may contribute to the development of autism. For the studies, the researchers sequenced the DNA of about 1,000 families, each of which had an autistic child. The gene mutations identified in the study...

(Ivanhoe Newswire) — Autism is a highly heritable neurodevelopmental disorder, yet the genetic underpinnings in the brain at young ages have remained largely unknown. But for the first time, researchers have identified in young autism patients genetic mechanisms involved in abnormal early brain development and overgrowth that occurs in the disorder Until now, few studies have been able to investigate whole-genome gene expression and genotype variation in the brains of young patients...
