Outline of Final Research Achievements

Two consanguineous families with multiple system atrophy were newly identified, and in total, six pedigrees with multiple system atrophy were subjected to this study. In the parametric linkage analysis allowing for heterogeneity, we did not find any apparent candidate loci. Subsequently, exome sequencing analysis was conducted in six probands with multiple system atrophy. Removing variants with a minor allele frequency > 0.1%, several candidate variants in the homozygous state remained in each pedigree. However, we did not detect any common variants shared in more than one family.
