Congenital microtia refers to abnormal outer ear development that typically affects hearing. This study uses a case-control study design, selecting 100 cases of congenital microtia patients and 100 normal controls, to study the role of DNA methylation in the pathogenesis of congenital microtia.The study will use gene chip technology to detect DNA methylation levels and gene expression differences between congenital microtia patients and normal controls. The study found that there were significant differences in DNA methylation levels and gene expression between congenital microtia patients and normal controls. Specifically, congenital microtia patients had lower levels of DNA methylation, and some genes were expressed at higher levels and others at 精品文档---下载后可任意编辑lower levels. These genes are mainly involved in biological processes such as ear development, cell proliferation and apoptosis.The results of this study show that DNA methylation plays an important role in the pathogenesis of congenital microtia. For future clinical practice, these results may provide a basis for discovering new biological mechanisms of congenital microtia, developing new molecular markers and treatments.Keywords: DNA methylation, congenital microtia, gene expression, case-control study
