GGH and acute myeloid leukemia: Without statistically significant difference, but there was a tendency that GGH mRNA abundance in leukemia cells from the 4 AML patients exhibiting hypermethylation of CpG2 (3.1439±2.5028) is lower than that in the AML controls without methylation in CpG1 or CpG2 (7.1365±5.0030) and 5 AML patients with hypomethylation of CpG2 (5.8276±3.9272).
