Recently, Zhang et al. (2018) reported the preliminary DNA methylation profiles in SCZ with TD by using methylated DNA immunoprecipitation coupled with next-generation sequencing in a case-control design in a Chinese sample17 and found that 161 genes were specific to TD group; however, the DLGAP2 gene was not reported. The gene discussed is DLGAP2; the disease is thanatophoric dysplasia.
