Figure 1From: Association of promoter methylation statuses of congenital heart defect candidate genes with Tetralogy of Fallot Median methylation levels in the promoter CpG islands of candidate genes of TOF cases and controls. (A) EGFR_ M1 median methylation level; (B) EVC2_ M1 median methylation level; (C) NFATC2_ M2 median methylation level. TSS, Transcription Start Sites; red vertical line, CpG sites; red thick bars, CpG islands; M, MassARRAY amplicon; The region between two arrows, target amplicon. *P < 0.05, **P < 0.01, ***P < 0.001 (Mann–Whitney test).Back to article page
