A recent collaborative study that combined linkage analysis with whole-genome sequencing of family members of multiplex families with multiple system atrophy (MSA) has identified COQ2 gene as a causative gene for MSA. The common variant, c.T1178C (p.V393A, rs148156462), in the COQ2 gene was found to be associated with an increased risk of sporadic MSA.(More)
A recent study identified a missense mutation in coiled-coil-helix-coiled-coil-helix domain-containing 2 (CHCHD2) gene, p.Thr61Ile, in a Japanese multigenerational family with autosomal dominant Parkinson's disease (PD). Subsequent analyses identified several genetic variants in this gene that contributed to increased risk of sporadic PD, making CHCHD2 a(More)
Whole-exome sequencing recently identified a homozygous truncating mutation in Synaptojanin 1 (SYNJ1, PARK20), p.Arg258Gln, in 2 independent families with autosomal recessive young-onset parkinsonism with seizures and cognitive decline. This mutation's role in typical Parkinson's disease (PD) is unclear. We sequenced all coding exons and exon-intron(More)
