Gene therapy

Arthur Nienhuis, a hematologist at St. Jude Children's Research Hospital in Memphis, Tenn., and president of the American Society of Gene Therapy, responds:

New developments and clinical trials breathe life back into gene therapy

A dopamine-receptor gene variation is linked to changes in brain function, possibly neurotransmitter signaling
