MTHFR C677 T gene polymorphism in lymphoproliferative diseases

Area of Science:

• Genetics
• Oncology
• Biochemistry

Background:

• Methylenetetrahydrofolate reductase (MTHFR) is crucial for folate metabolism.
• MTHFR gene polymorphisms are linked to various diseases, including cancer.
• The MTHFR C677 T polymorphism is common and studied for its health implications.

Purpose of the Study:

• To investigate the association between the MTHFR C677 T polymorphism and lymphoproliferative diseases.
• To compare the frequency of the MTHFR C677 T variant in patients with Hodgkin's lymphoma (HL) and B-cell neoplasms (BCNs) versus healthy controls.

Main Methods:

• Melting curve analysis was employed to genotype the MTHFR C677 T polymorphism.
• A case-control study design was used, comparing 117 patients with lymphoproliferative diseases to 154 age- and sex-matched controls.

Main Results:

• The MTHFR 677 T variant was less frequent in the overall patient group (26%) compared to controls (33.7%; P=0.05).
• Patients with Hodgkin's lymphoma (HL) showed a significantly lower frequency of the 677 T allele (20.5%; P=0.01) and a higher frequency of the 677CC genotype.
• The variant allele frequency in B-cell neoplasms (BCNs) was similar to controls (30.3%; P=0.47).

Conclusions:

• The MTHFR C677 T polymorphism distribution differs among lymphoproliferative diseases.
• The reduced frequency of the MTHFR 677 T variant in HL suggests a potential protective role or altered disease mechanism.
• Further research is needed to clarify the specific role of MTHFR polymorphisms in different hematological malignancies.
