Abstract

To understand the genetic origin of I2020T mutation in the kinase domain of leucine rich repeat kinase 2 (LRRK2), we investigated the original PARK8 Japanese family (Sagamihara family) and a German family (family 32), both of which were found to harbor I2020T as the causal mutation for autosomal dominant familial Parkinson's disease (PD). Microsatellite-haplotype analysis around the LRRK2 gene indicated that the mutation-carrying haplotypes of the two families were distinct from each other. This indicated that the I2020T mutation, an essential pathogenic mutation of PARK8-related PD, had occurred independently in the two PD families.
