“The Molecular Genetics of Pathological Gambling”
Principal Investigator: David E. Comings, MD, The City of Hope National Medical Center
Awarded $159,900 in 1997
Aim: Investigate association between pathological gambling and multiple dopamine receptor genes thus lending support for the idea that people with gambling disorders have a deficient reward center that predisposes them to developing a gambling disorder.
