In the study of "Mitochondrial diseases associated with cerebral folate deficiency"
Garcia-Cazorla A, Quadros EV, Nascimento A, Garcia-Silva MT, Briones P, Montoya J, Ormaz√°bal A, Artuch R, Sequeira JM, Blau N, Arenas J, Pineda M, Ramaekers VT., posted in, researchers indicated that Half of our patients (14 out of 28) had CFD.However, 5 out of these 14 patients had KSS, a mitochondrial DNA deletion giving rise to pigmentary retinopathy, external ophthalmoplegia, ataxia, and aberrant cardiac conduction, which is a well recognized entity associated with low CSF folate levels......high dose of
folinic acid supplementation (from 1 to 3 mg/kg/ day) to correct low CSF 5-MTHF may be recommended in these disorders.
