      abstract     = {Genome-wide association studies (GWASs) have been
                      successful at identifying single-nucleotide polymorphisms
                      (SNPs) highly associated with common traits; however, a
                      great deal of the heritable variation associated with common
                      traits remains unaccounted for within the genome.
                      Genome-wide complex trait analysis (GCTA) is a statistical
                      method that applies a linear mixed model to estimate
                      phenotypic variance of complex traits explained by
                      genome-wide SNPs, including those not associated with the
                      trait in a GWAS. We applied GCTA to 8 cohorts containing
                      7096 case and 19 455 control individuals of European
                      ancestry in order to examine the missing heritability
                      present in Parkinson's disease (PD). We meta-analyzed our
                      initial results to produce robust heritability estimates for
                      PD types across cohorts. Our results identify $27\%$ $(95\%$
                      CI 17-38, P = 8.08E - 08) phenotypic variance associated
                      with all types of PD, $15\%$ $(95\%$ CI -0.2 to 33, P =
                      0.09) phenotypic variance associated with early-onset PD and
                      $31\%$ $(95\%$ CI 17-44, P = 1.34E - 05) phenotypic variance
                      associated with late-onset PD. This is a substantial
                      increase from the genetic variance identified by top GWAS
                      hits alone (between 3 and $5\%)$ and indicates there are
                      substantially more risk loci to be identified. Our results
                      suggest that although GWASs are a useful tool in identifying
                      the most common variants associated with complex disease, a
                      great deal of common variants of small effect remain to be
                      discovered.},
