Increased Genetic Change In Regions Of Genome Instability Linked To Autism
2013-04-03 15:34:58

Penn State Science – Eberly College of Science Children with autism have increased levels of genetic change in regions of the genome prone to DNA rearrangements, so called "hotspots," according to a research discovery to be published in the print edition of the journal Human Molecular Genetics. The research indicates that these genetic changes come in the form of an excess of duplicated DNA segments in hotspot regions and may affect the chances that a child will develop autism -- a...

New Study Suggests Misregulated Genes May Play Big Role In Autism
2013-03-21 12:52:01

Brown University A new study finds that two genes individually associated with rare autism-related disorders are also jointly linked to more general forms of autism. The finding suggests a new genetic pathway to investigate in general autism research. The genes encode the proteins NHE6 and NHE9, which are responsible for biochemical exchanges in the endosomes of cells. Mutations in the NHE6 gene are a direct cause of Christianson Syndrome, while mutations in the NHE9 gene lead to a...

Study opens promising new direction in autism research Autism Speaks, the world´s leading autism science and advocacy organization, today announced a study  supported by one of Autism Speaks´ first Suzanne and Bob Wright Trailblazer Awards, presents a new theory that autism may result from chronic danger signaling by mitochondria, cell structures that supply our cells with energy. This study by Trailblazer researcher and mitochondrial medicine specialist Robert Naviaux,...

Altered Gene Linked To Some Autism Behaviors
2013-02-13 09:25:54

Washington University School of Medicine Scientists at Washington University School of Medicine in St. Louis have identified a genetic mutation that may underlie common behaviors seen in some people with autism, such as difficulty communicating and resistance to change. An error in the gene, CELF6, leads to disturbances in serotonin, a chemical that relays messages in the brain and has long been suspected to be involved in autism. The researchers identified the error in a child with...

Fragile X Syndrome Linked To Nearly 100 Autism Genes
2012-12-13 15:28:13

Connie K. Ho for redOrbit.com — Your Universe Online Researchers from Duke University Medical Center and Rockefeller University recently discovered that the gene responsible for fragile X syndrome is connected to almost 100 other genes that have been linked to autism. While researchers have long been aware of a relationship between fragile X syndrome and autism, this is the first time that they have begun to trace out the exact genetic pathways that link the two disorders...

A new study published in Biological Psychiatry suggests that autism is associated with reductions in the level of cellular adhesion molecules in the blood, where they play a role in immune function. Cell adhesion molecules are the glue that binds cells together in the body. Deficits in adhesion molecules would be expected to compromise processes at the interfaces between cells, influencing tissue integrity and cell-to-cell signaling. In the brain, deficits in adhesion molecules could...

Study Finds Link Between Autism And Pollution
2012-11-27 15:34:55

Lee Rannals for redOrbit.com — Your Universe Online According to a study published in the Archives of General Psychiatry, polluted air could increase the risk for a child to develop autism. The study shows that exposure to traffic-related air pollution during pregnancy and the first year of life is associated with more than a two-fold risk of autism. The team from the University of Southern California and Children's Hospital Los Angeles also found that exposure to...

New computational analysis identifies gene networks affected in schizophrenia and shows that schizophrenia and autism share related genetic networks, each composed of hundreds of genes Although schizophrenia is highly genetic in origin, the genes involved in the disorder have been difficult to identify. In the past few years, researchers have implicated several genes, but it is unclear how they act to produce the disorder. A new study by researchers at Columbia University Medical Center...

Genetics of Autism Help Detect At-Risk Kids
2012-09-13 11:45:47

Connie K. Ho for redOrbit.com — Your Universe Online For people with Autism Spectrum Disorder (ASD), the basic communication skills and behavioral habits that we take for granted on a daily basis can be socially debilitating obstacles. As such, an increasing amount of research is going on in this field largely in response to the growing number of cases diagnosed each year. A potentially critical study from researchers at University of Melbourne was published in the journal...
