Children with ALL (n = 96) were screened for GCPII C1561T, RFC1 G80A, cSHMT C1420T, TYMS 5´-UTR 2R3R, TYMS 3´-UTR ins6/del6, MTHFR C677T, MTR A2756G polymorphisms using PCR-RFLP and PCR-amplified fragment length polymorphism techniques.
In a case-control study, we evaluated whether four common polymorphisms in methylenetetrahydrofolate reductase (MTHFR C677T and A1298C), methionine synthase (MS A2756G), and methionine synthase reductase (MTRR A66G) genes may have a role in altering susceptibility to adult acute lymphoblastic leukemia (ALL) and non-Hodgkin's lymphoma (NHL).
Polymorphisms in methionine synthase (MS A2756G), cytosolic serine hydroxymethyltransferase (SHMT1 C1420T), and a double (2R2R) or triple (3R3R) 28-bp tandem repeat in the promoter region of thymidylate synthase (TS) were studied and found to modulate ALL risk.
