Homocysteine Serum Levels and Methylenetetrahydrofolate (MTHFR) C677T Genotype in Patients with Parkinson's Disease, with and without Levodopa Therapy _ Crimson Publishers
Homocysteine Serum Levels and Methylenetetrahydrofolate (MTHFR) C677T Genotype in Patients with Parkinson's Disease, with and without Levodopa Therapy by Eleonora DŽoljić* and Vladimir Kostić in Degenerative Intellectual & Developmental Disabilities Both methylenetetrahydrofolate (MTHFR) C677T genotype and levodopa treatment may give rise to elevated serum homocysteine levels in parkinsonian patients. We aimed to clarify the interplay of these factors in pathogenesis of Parkinson's disease (PD)-related hyperhomocysteinemia . Total serum levels of homocysteine (tHcy) and MTHFR C677T genotype were investigated in levodopa -treated and -untreated parkinsonian ("de novo”) patients, as well as in control healthy subjects matched by age and gender (N=83, 30 and 53, respectively). MTHFR C677T genotypes were equally distributed in PD patients and control subjects, the T allele homozygosity being observed in app. 12-17% cases. https://crimsonpublishe...
