Rare autosomal recessive variants in DJ-1, a causative gene for early-onset Parkinson’s disease, have been associated with a variety of clinical syndromes in a limited number of patients. Here, we report a case of a novel DJ-1 variant in a 39-year-old man with a 4-year history of parkinsonism, cognitive dysfunction, and lower limb spasticity. He was diagnosed with Parkinson’s disease. Genetic testing of the patient revealed compound heterozygous variants in the DJ-1 gene (exon 6 deletion + c.242dup), of which exon 6 deletion was a novel variant. We conclude that variants in DJ-1 should be considered possible causes of early-onset parkinsonism with spasticity and cognitive impairment, as in this case.
