  1. aGenotyping data and mRNA expression levels for MTHFR by genotypes were obtained from the HapMap phase II release 28 data from EBV-transformed lymphoblastoid cell lines from 209 individuals.
  2. bOnly 5 cases among CEU were detected with TT genotype.
  3. cP value of independent t-test for between sub-group heterogeneity.
