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...

Gene co-expression study is based on data in the Allen Mouse Brain Atlas A team of scientists has obtained intriguing insights into two groups of autism candidate genes in the mammalian brain that new evidence suggests are functionally and spatially related. The newly published analysis identifies two networked groupings from 26 genes associated with autism that are overexpressed in the cerebellar cortex, in areas dominated by neurons called granule cells. The team, composed of...

Full Genome Sequencing Autistic Patients

Rebekah Eliason for redOrbit.com - Your Universe Online New full genome sequencing performed on individuals with autism spectrum disorder (ASD) and their family members has provided a complete inspection of the vast genetic variations associated with ASD. This study was a collaborative effort formed by the world's leading ASD advocacy group Autism Speaks. Included in the results were both spontaneous and inherited genetic variations that were found in one half of the families sequenced....

Selection in European populations of genes regulated by FOXP2, a key factor in development and language Researchers have designed a method that can universally test for evolutionary adaption, or positive (Darwinian) selection, in any chosen set of genes, using re-sequencing data such as that generated by the 1000 Genomes Project. The method identifies gene sets that show evidence for positive selection in comparison with matched controls, and thus highlights genes for further functional...

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...
