Delay (months) between the first administration of AZA/6-MP and the occurrence of bone marrow toxicity. Patients classified as low methylators (LM; n = 4) were homozygous for 1 nonfunctional mutation or heterozygous for 2 nonfunctional mutations; patients classified as intermediate methylators (IM; n = 7) were heterozygous for 1 nonfunctional mutation; and patients classified as high methylators (HM; n = 29) were homozygous for the wild-type or heterozygous for 2 functional alleles. One patient was heterozygous for a previously unknown mutation.
