[Abstract]:Objective to investigate the role of p63 gene methylation in the pathogenesis of non-syndromic cleft lip and palate (NSCL / P) by detecting the methylation of p63 gene in peripheral blood of patients with non-syndromic cleft lip and palate (NSCL / P). To explore the pathogenesis of non-syndromic cleft lip and palate. Methods 120 cases of non-syndromic cleft lip and palate and 90 cases of trauma without congenital malformation were selected from oral and maxillofacial surgery, affiliated hospital of Qingdao University. Among them, 58 cases were males and 62 cases were females. There were 31 cases of simple cleft lip, 55 cases of simple cleft palate, 34 cases of cleft lip with cleft palate, 58 cases of male and 32 cases of female with trauma. The peripheral anticoagulant DNA was extracted and the MSP template was obtained by Bisulfite treatment of DNA sample. The methylation status of p63 gene was detected by DNA methylation specific PCR. The positive cases of p63 gene methylation in patients with congenital cleft lip and palate and trauma were calculated, and 蠂 2 test was performed by SPSS22.0 software. The p63 methylation status was compared between non-syndromic cleft lip with or without cleft palate, simple cleft lip, simple cleft palate and cleft lip with cleft palate with trauma, as well as the positive rate of p63 methylation among different cleft lip and palate types. To analyze the correlation between the methylation status of p63 gene and non-syndromic cleft lip and palate. Results the positive rate of p63 methylation was 72.5% (87 / 120) in peripheral blood and 40.0% (36 / 90) in control group. The positive rate of p63 gene methylation in patients with non-syndromic cleft lip and palate was significantly higher than that in patients with trauma (蠂 ~ 2 = 22.386, P 0.001). There was a significant correlation between the methylation status of p63 gene and non-syndromic cleft lip with or without cleft palate. The positive rate of p63 gene methylation in patients with simple cleft lip was significantly higher than that in patients with trauma (蠂 24.215P 0.0400.05), the status of p63 methylation was correlated with simple cleft lip, the positive rate of methylation of p63 gene in patients with simple cleft palate was higher than that in patients with trauma. The difference was statistically significant (蠂 ~ 2 / 22.085 / P0.001), and there was a significant correlation between p63 methylation and congenital cleft lip, and the positive rate of p63 gene methylation in patients with congenital cleft lip and cleft palate was higher than that in patients with trauma. There was a significant correlation between cleft lip and cleft palate with p63 methylation, and the positive rate of p63 gene methylation in patients with simple cleft lip was higher than that in patients with simple cleft palate. There was no significant difference in p63 methylation between simple cleft lip and simple cleft palate (蠂 2 / 3.542P 0.060.05), and the positive rate of p63 gene methylation in patients with simple cleft lip was higher than that in patients with congenital cleft lip and cleft palate. There was no significant difference in p63 gene methylation between congenital cleft lip and congenital cleft lip with cleft palate (蠂 2 / 0.626), and the positive rate of p63 gene methylation in patients with simple cleft palate was higher than that in patients with congenital cleft lip and cleft palate. There was no significant difference in the sensitivity of p63 gene methylation between congenital cleft palate and congenital cleft lip with cleft palate. Conclusion the methylation status of p63 gene is associated with the occurrence of non-syndromic cleft lip and palate. By studying the correlation between p63 gene methylation and congenital cleft lip and palate, we can achieve accurate diagnosis, prenatal evaluation, genetic consultation and so on. The prevention of cleft lip and palate provides another new basis.
