title: Anticipation of onset age in familial Parkinson's disease without SCA gene mutations.
abstract: Assessment of a series of 279 cases with Lewy body disease revealed 14 families having a family history consistent with autosomal dominant inheritance, eight of these with dominant Parkinsonism and six with dominant dementia. Analysis of the age at onset and genetic features in these families revealed significant anticipation only in a subset of parkinsonian families, with no pathological alleles for spinocerebellar ataxias or the common alpha-synuclein or LRRK2 point mutations.
