ABSTRACT
The associations of GRIN2B polymorphism (rs1806201) with alcohol withdrawal and related clinical parameters in alcohol dependent subjects were investigated. Cases were assessed using a semi-structured clinical pro forma for alcohol abuse and a questionnaire for family history of alcohol dependence and psychiatric disorders after obtaining informed consent. The study included alcohol dependent male cases (n = 220, age at onset of alcohol withdrawal symptoms = 32.4 ± 8.8 y) recruited at the Center for Addiction Medicine, National Institute of Mental Health and Neurosciences, Bangalore, India. The controls comprised of healthy unrelated males (n = 183) who were ethnically matched and selected randomly. The polymorphism rs1806201 was analyzed by polymerase chain reaction and restriction fragment length polymorphism. The presence of T allele at this locus was significantly associated with lower age at onset of alcohol withdrawal symptoms (p = .005) among the cases. Mean age at onset of alcohol withdrawal symptoms in subjects who were T carriers was 31.4 ± 8.5 y (n = 160) and non-T carriers was 35.2 ± 9.0 y (n = 60). The SNP rs1806201 in GRIN2B may play an important role in genetic susceptibility to earlier age of withdrawal in alcohol dependent patients.
