This international study, done by Mayo Clinic, has found a certain gene variant that was connected to the treatment with acamprostate and sober success length. Acamprosate is a commonly used prescribed drug that help recovering alcoholic patients. The gene variant that was being observed was rs2058878 located in gene GRIN2B. The results showed that patients that were carrying this gene as well as taking acamprostate stay sober longer than the patients who didn't. Collaborators from Germany also repeated this study and found the same results.
