    Abstract

    Background Although several Mendelian genes causing Parkinson's disease are known, these are relevant to only a small proportion of total cases.1 The significant variation in disease expression (presence, pattern and severity of motor and non–motor features, and progression rates), however, is likely to be influenced by genetic variation (single nucleotide polymorphisms) at several loci.

    Objectives To record variations in clinical features (including progression rates) in Parkinson's disease, in a prospective cohort study, in recently diagnosed and young onset patients, and relate these observations to genetic differences. To identify a plasma biomarker in Parkinson's disease from proteomic studies. To support collaborative research through the development of an accessible data and tissue sample bio–bank.

    Methods In a multicentre UK–wide collaboration by the Parkinson's Repository of Biosamples and Networked Datasets clinical consortium (PRoBaND), patients diagnosed within the preceding 3 years (n=2200), diagnosed before the age of 50 years (n=240), and first–degree relatives of both (mainly siblings, n=760), are being enrolled for standardised clinical observations and patient–filled questionnaires obtained, including demographics, family history, motor and non–motor involvement, quality of life, and response to therapy. Data recording and storage uses an online networked database. There are 6 monthly visits over 3 years. Blood samples are collected for genotyping for rare (including GBA, LRRK2, SNCA and PARKIN) and common polymorphisms. Plasma is frozen at –800C in 6 aliquots per case per visit, every 18 months for proteomic analysis.

    Results 1000 Parkinson's disease patients (recent onset n=760, young onset n=240) have been recruited over 11 months to January 2013 across 49 sites, and are the subject of this interim report. In recent onset patients, mean age at diagnosis was 66.5 years (SD 9.2), mean disease duration 1.4 years (SD 0.9), and 63.6% are male. 40.2% of these patients were entered to the study <1y from diagnosis, 28.2% at 1–2y from diagnosis, and 31.6% at 2–3y from diagnosis. Of these 11.8% were drug naïve at study entry. In young onset patients, mean age at diagnosis was 43.6 years (SD 5.8), mean disease duration 10.2 years (SD 6.8), and 69.3% are male.

    Conclusion We have been successful in establishing a large effective clinical research network actively recruiting cases to a combined clinical–laboratory programme, evaluating variation in the clinical expression of Parkinson's disease, which will be studied in relation to genetic and other biological parameters.
