Abstract
Fine mapping of calcineurin (PPP3CA) gene identified single nucleotide polymorphisms (SNPs) and simple sequence repeat polymorphisms that are associated with addiction vulnerability. A trinucleotide repeat marker, located in the 5'untranslated region (5'UTR) of the PPP3CA mRNA, exhibited significantly different genotype and allele frequencies between abusers and controls in the NIDA African-American sample. The polymorphism showed allelic-specific expression in mRNA extracted from postmortem brain specimens. Novel alternatively spliced isoforms of PPP3CA were identified and their expressions were found altered in brain regions of postmortem Alzheimer's disease patients. These data underscore the importance of calcineurin gene in the molecular mechanism of addiction and Alzheimer's diseases.Entities:
