GABRB2 and schizophrenia: The positive ‘0.00’ co-localizations formed by the Alu elements toward REG and GENE indicate the highly significant enrichment of these elements in the vicinity of REG and GENE, as illustrated by the importance of an AluY-containing segment in GABRB2 in schizophrenia etiology25, and the efficient capture of genic regions for sequence analysis by the AluScan platform developed by our laboratory based on inter-Alu polymerase chain reaction employing multiple Alu consensus sequence-based primers with opposite orientations12, 26, 27.
