[Clinical and genetic analysis of juvenile parkinsonism in Russia].

Clinical and genetic analysis of juvenile parkinsonism was performed in 26 sibs from 20 families. Heterogeneity of the disorder was observed. Mutations in the parkin gene (locus PARK2, chromosome 6q25.2-27), with the prevalence of deletions over point mutations, have been identified in 41%. The comparative clinical analyses of patients examined confirmed the phenotypical polymorphism of "parkinopathy". We also showed the absence of asymmetric manifestation--an important and underestimated so far sign of the disease. The results of the study may be considered as a valuable clue to the clinical diagnosis of parkin-related juvenile parkinsonism in Russian population and implemented for mutation screening and medico-genetic counseling of affected families.
