Note: For some SNPs, testing providers detect the genotype from the opposite strand of DNA, so that the genotypes listed on openSNP don't appear here. In those cases, please replace "A" by "T" or "G" by "C" (and vice-versa).

||Low clinical importance, Likely pharmacogenetic
||Usually this variant is found in combination Y240C, forming the TPMT*3A variant. When alone, this variant produces the *3B variant. Both variants are associated with loss of thiopurine methyltransferase (TPMT) activity. Inability to metabolize thiopurine drugs can lead to severe adverse reactions. Heterozygotes may be advised to take a reduced dosage due to reduced metabolism of the drug.
