PG - 1332-5 AB - We report white monozygotic twins with moyamoya disease (MMD) (adult ischemic type). Both had cerebral angiography, MRI, magnetic resonance angiography, SPECT, EEG, human leukocyte antigen (HLA) typing, evaluation of thrombophilia, and immunologic and karyotype analysis. The clinical features and HLA phenotypes described in Asian monozygotic twins with MMD were not found in our patients. However, genetic analysis revealed a homozygous state for C-->T (Ala-->Val substitution) in position 677 of the methylenetetrahydrofolate reductase-encoding gene.
