-Synuclein Locus Triplication Causes Parkinson's Disease

Mutations in the α-synuclein gene ( SNCA ) in the Contursi kindred ([ 1 ][1]) implicated this gene in Parkinson's disease (PD). Subsequently, α-synuclein was identified as the major component of Lewy bodies, the pathological hallmark of PD, and of glial cell cytoplasmic inclusions ([ 2 ][2]). We
