Notably, we confirmed the identification of 2 stop‐gain mutations, to our knowledge previously unreported, having checked the PDmutDB,10, 11 1000 Genomes Project,17 ExAC database (http://exac.broadinstitute.org/, accessed April 26, 2016) and the dbSNP database18: p.Arg1552Ter in LRRK2, which was found in 1 heterozygote carrier (Cas55), and p.Trp90Ter in PINK1, which was found in homozygosis (Cas154) and could also represent a new causal variant for PD (see Figure S2). This evidence concerns the gene LRRK2 and Parkinson disease.
