How genetic malfunction causes a form of retardation

Researchers have discovered that the genetic malfunction that causes a form of mental retardation called Noonan Syndrome produces an imbalance in the genesis of two types of cells in the developing embryonic brain. This imbalance, they theorize, could explain how the genetic abnormality gives rise to the neural pathology of the disorder. More broadly, they said, the new insight into the mechanism underlying NS could apply to other inherited forms of retardation.

1. Fragile X retardation syndrome corrected in mice
   12-19-2007 · EurekAlert!
   Researchers working with mice have significantly alleviated a wide range of abnormalities due to fragile X syndrome by altering only a single gene, countering the effects of the fragile X mutation. They said their achievement offers the potential for treatment of the disorder, the most common form of inherited mental retardation and a leading identified genetic cause of autism. There is currently no treatment or therapy for fragile X syndrome, whose symptoms include mental retardation, epilepsy and abnormal body growth.

   10-18-2006 · EurekAlert!
   Researchers have pinpointed why mutations that cause Rett Syndrome (RTT) -- among the leading causes of mental retardation in females -- specifically target the brain rather than other body tissues. They said their findings yield important insight into the origin and course of the disease.

   09-27-2007 · EurekAlert!
   A study by Yale researchers offers a new view of what causes the greatest genetic variability among individuals -- suggesting that it is due less to single point mutations than to the presence of structural changes that cause extended segments of the human genome to be missing, rearranged or present in extra copies.

   02-07-2007 · EurekAlert!
   Scientists have discovered that the ubiquitous bacteria that causes most painful stomach ulcers has been present in the human digestive system since modern man migrated from Africa over 60,000 years ago. They compared DNA sequence patterns of humans and the Helicobacter pylori bacteria now known to cause most stomach ulcers and found that the genetic differences between human populations that arose as they dispersed from Eastern Africa over thousands of years are mirrored in H.pylori.

6. New antibody for EGFR causes lung cancer regression
   01-25-2007 · EurekAlert!
   Mutant forms of the protein EGFR are involved in lung cancer development in many individuals, but not all individuals express the same mutant EGFR. A new study shows that both a mouse EGFR-specific antibody (mAb806) and its humanized form (ch806) cause lung tumor regression in two mouse models of lung cancer, leading to the suggestion that ch806 might provide a new approach to treat patients with lung cancer driven by mutant forms of EGFR.

   University of Iowa researchers and collaborators have identified new genetic mutations that likely cause the common form of cleft lip and palate. The results could eventually help clinicians predict a family's risk of having more children with the condition. The findings appear in the week of March 5 online Early Edition of the Proceedings of the National Academy of Sciences.

   Researchers at Rensselaer Polytechnic Institute are challenging current thinking on the causes and prevention of Alzheimer's disease, offering a new hypothesis that could be the key to preventing this form of dementia. The researchers have found that a specific imbalance between two peptides may be the cause of the fatal neurological disease that affects more than five million people in the United States.
