Cholinergic pathways have been widely implicated in cognition and memory, making the respective genes excellent candidate markers for cognitive abilities. Identification of a possible role of cholinergic receptor genes in humans has been hampered by the lack of reported polymorphisms. The authors identified a common AT 1890 polymorphism in the 3'UTR of the CHRM2 gene. To determine if it was associated with IQ, the authors examined 358 adult males and 470 adult females for a total of 828 adults. The subjects were the parents of twins from the Minnesota Twin and Family Study, a long-term study of the genetics and environmental factors in substance abuse. All subjects in the CHRM2 study were of Caucasian ancestry. All were given the Wechsler Adult Intelligence Scale-Revised (Vocabulary, Information, Block Design, and Picture Arrangement) test. The study was approved by the internal review boards of both the Unive
