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).

||Alone, this variant is known as TPMT*3C -- but often, especially in Caucasians, it is found together with another nonsynonymous variant (A154T) to produce the TPMT*3A variant. Both variants are associated with loss of thiopurine methyltransferase (TPMT) activity, although *3C is milder than *3A. 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.
