In conclusion, MTHFR C677T was linked to a significant 2.4-fold decreased risk of developing childhood ALL, whereas MTHFR A1298C did not significantly affect the risk of ALL in our population.

In this study we describe the genotyping of the MTHFR C677T polymorphism by melting curve analysis with the LightCycler in a case-controlled study of patients with acute lymphocytic leukemia (ALL), myelogenous leukemia (AML), and chronic myelogenous leukemia (CML), and assess the effect of this common polymorphism on the leukemia risk in adult patients in Turkey.

We have analyzed the MTHFR C677T polymorphism in 52 patients and 88 control individuals, all ethnic Greek residents of northern Greece, and examined the association of this polymorphism with (a) susceptibility to childhood ALL and (b) the distribution of average plasma alanine aminotransferase (ALT) levels, white blood cell counts (WBC), and hemoglobin levels (Hb) during the induction and consolidation phases of treatment.

No significant difference was detected between responder and non-responders according to MTHFR T677C polymorphism, but the patients who had TT genotype respond 1.75-fold worse than CC (OR, 0.57; 95% CI, 0.07-4.64) in ALL patients (p=0.59), and in DLBCL, CT genotype revealed a 1.8-fold worse response than CC genotype (OR, 0.54; 95% CI, 0.17-1.7), but TT genotype revealed 2.6-fold better response rates than patients with CC genotype (OR, 2.6; 95% CI, 0.26-26.8).

Certain common polymorphisms within the MTHFR gene (C677T, A1298C) result in reduced enzymatic activity and have been associated with reduced risk for a variety of cancers such as acute lymphocytic leukemia, lung and colorectal cancer.
