Autism Study Advances Understanding of Gene-Environment Interactions

New study uses brain tissue to deepen understanding of the roles that genetics and environment play in autism spectrum disorder
September 06, 2013

A new study using human brain tissue from the Autism Tissue Program (ATP), an Autism Speaks translational research program, identifies new genes of interest in understanding the genetic and environmental interaction in ASD. Appearing in the recent issue of Molecular Psychiatry, the study conducted by six researchers from Johns Hopkins, analyzed tissue from multiple areas of the brain known to be affected by autism.

Newly Discovered Autism Gene Opens New Avenue of Research

April 05, 2012

Scientists have discovered a gene whose expression is twelve times higher than normal in the brains of persons with autism. The gene, dubbed MSNP1AS, may increase autism risk in a manner that has been little studied in the past.

Autism Researchers Discover ‘Epigenetic’ Changes

Findings suggest how genes and environmental stresses may interact to cause autism
November 07, 2011

 

  In recent years, scientists have identified rare genetic mutations that in and of themselves can produce autism. They have likewise found a large number of genetic changes that increase the risk that a child will develop this disorder. However, fewer than 20 percent of those with an autism spectrum disorder (ASD) harbor identifiable gene defects directly related to the disease.
