Male-specific association between dopamine receptor D4 gene methylation and schizophrenia.
<h4>Objective</h4>The goal of our study was to investigate whether DRD4 gene DNA methylation played an important role in the susceptibility of Han Chinese SCZ.<h4>Methods</h4>Using the bisulphite pyrosequencing technology, DNA methylation levels of 6 CpG dinucleotides in DRD4...
