Article abstract The G209A mutation in the α-synuclein gene has been associated with
autosomal dominant PD (ADPD) in a family from Contursi, Italy, and three apparently
unrelated Greek families. Several groups around the world failed to identify the G209A
mutation in a sizable series of familial and sporadic cases of PD. The authors present two
additional Greek families with ADPD associated with the G209A mutation. In both families,
asymptomatic carriers older than the expected age at onset were found.
