We describe a sporadic case of atypical parkinsonism-dystonia of subacute onset at the age of 16 years in a male from a consanguineous family. He showed marked orofacial dystonia, levodopa- induced dyskinesia, and a stereotyped bilateral eye-pressing movement disorder. We combined Sanger sequencing of candidate genes, homozygosity mapping, and whole-exome sequencing. A homozygous mutation was identified disrupting a splice site in exon 5 of the DJ1 (PARK7) gene. Clinical details and a video are provided. DJ1 mutations are a rare cause of atypical complex parkinsonism. Exome sequencing is efficacious in identifying the causal gene variant.
