UCLA researchers led by Dr. Donald Kohn have created a method for modifying blood stem cells to reverse the genetic mutation that causes a life-threatening autoimmune syndrome called IPEX. The gene therapy, which was tested in mice, is similar to the technique Kohn has used to cure patients with another immune disease, severe combined immune deficiency, or SCID, also known as bubble baby disease.

Exposure to small amounts of lead may contribute to attention deficit hyperactivity disorder (ADHD) symptoms in children who have a particular gene mutation, according to new research.

A study from the University of Copenhagen reveals that every single person on the Earth had brown eyes until a genetic mutation occurred around 10,000 years ago. Researchers interpret that all people with blue eyes share a common ancestor.

An Iranian scientist Omid Goodarzi at Cedars-Sinai Hospital, Los Angeles, has identified a new genetic mutation that appears to protect people from developing type 2 diabetes.
