Allele specific analysis of the ADRBK2 gene in lymphoblastoid cells from bipolar disorder patients.

ABSTRACT: G-protein coupled receptor kinase-3 (GRK3), translated from the gene, ADRBK2 has been implicated as a candidate molecule for bipolar disorder through multiple, converging lines of evidence. In some individuals, the ADRBK2 gene harbors the A-haplotype, a collection of single nucleotide polymorphisms (SNPs) previously associated with an increased risk for bipolar disorder. Because the A-haplotype encompasses the ADRBK2 promoter, we hypothesized that it may alter the regulation of gene expression. Using histone H3 acetylation to infer promoter activity in lymphoblastoid cells from patients with bipolar disorder, we examined the A-haplotype within its genomic context and determined that at least four of its SNPs are present in transcriptionally active portions of the promoter. However, using c
