CORVALLIS, Ore. – A study that tracked genetic mutations through the human equivalent of about 5,000 years has demonstrated for the first time that oxidative DNA damage is a primary cause of the process of mutation – the fuel for evolution but also a leading cause of aging, cancer and other diseases.
A genetic search that wound its way from patients to mouse models and back to patients has uncovered an unlikely gene critically involved in a common birth defect which causes mental retardation, motor delays and sometimes autism, providing a new mechanism and potentially improving treatment for the disorder.
By Debra Kain — An international group of researchers is the first to show that common variations in a gene – previously shown to be associated with Retts Syndrome, autism, and mental retardation – are associated with differences in brain structure in both healthy individuals and patients with neurological and psychiatric disorders. Their findings will be published in the early online edition of the Proceedings of the National Academy of Sciences the week of August 17.
CANCER RESEARCH UK funded scientists have confirmed that inherited changes in certain regions of the genome can increase a smokers' risk of developing lung cancer lung cancer, and determine the type of lung cancer that develops. Their results were published in this week's edition of the journal Cancer Research.
