Genetic Abnormalities Found in Some ALS Patients

Researchers have discovered abnormalities in the chromosomes of several patients with sporadic, or non-hereditary, ALS, according to a study published in the April 22 issue of Neurology, the scientific journal of the American Academy of Neurology. ALS, or amyotrophic lateral sclerosis, is a progressive disease of the nervous system also known as Lou Gehrig’s disease.

New Genetic 'Fishing Net' Harvests Elusive Autism Gene

Researchers have developed a new statistical genetic “fishing net” that they have cast into a sea of complex genetic data on autistic children to harvest an elusive autism gene.
Moreover, the researchers said that the success of the approach will be broadly applicable to studying genetic risk factors for other complex genetic diseases, such as hypertension, diabetes and multiple sclerosis. In this case, the gene, which encodes part of a brain neurotransmitter docking station called the gamma-Aminobutyric Acid Receptor beta3-subunit (GABRB3), has been implicated in autism previously, but never positively linked to the disease. Their findings will be published in the March 2003 issue of the American Journal of Human Genetics.
