Sequencing analysis of those genes (including parkin/PARK2, PINK1 and DJ1/PARK7, as well as the common dystonia gene DYT1) associated with autosomal recessive Parkinson’s disease or parkinsonism did not identify any pathogenic variants, aside from some SNPs (Single nucleotide polymorphisms) noted in three databases (LOVD Parkinson’s Disease Mutation Database, Human Gene Mutation Database and SNP Database). Here, PARK7 is linked to Dystonia.
