Figure 2. Methylated fraction in the PCFT gene in normal placenta (n = 4), leukocytes from subjects with low tHcy (c = 5–10 µmol/L, n = 10–25), and leukocytes from subjects with high tHcy (c = 20–113 µmol/L, n = 11–25). The error bars show ± 1 SD. The upper panel shows CpG sites 1–30 and the lower panel shows CpG sites 31–52.
