VPS35 Parkinson's disease phenotype resembles the sporadic disease.

Recently a new autosomal dominant Parkinson's disease mutation (p.Asp620Asn) in the VPS35 gene was discovered. The clinical features of 14 PD patients with this mutation from three Austrian families were evaluated. Age at disease-onset appears lower and depression was more common in Austrian patients compared to sporadic PD patients. However, we were unable to identify a specific clinical maker of VPS35 patients, who otherwise resemble sporadic PD patients.
