BACKGROUND: Recently, the LRP10 gene has been identified as a novel genetic cause in individuals affected by Parkinson's disease (PD), Parkinson's disease dementia, or dementia with Lewy bodies.

OBJECTIVE: We investigated the involvement of LRP10 mutations in Chinese patients with familial PD and reviewed previous studies of LRP10 mutations in patients with PD.

METHODS: A mutation analysis of the LRP10 gene was performed in a cohort of 205 unrelated Chinese patients with familial PD. Burden analysis was conducted using data from the Genome Aggregation Database and 5 genetic studies of LRP10 in patients with PD (including our cohort).

RESULTS: A total of 3 novel potentially pathogenic variants, c.32T>A (p.L11H), c.1184G>A (p.R395H), and c.1333G>A (p.A445T), were detected in 3 probands of our cohort. However, burden analysis argued against an overrepresentation of variant alleles in patients with PD.

CONCLUSIONS: Genetic screening of the LRP10 gene in our cohort may provide independent, albeit limited, evidence for the pathogenicity of LRP10 in familial PD. Burden analysis using data from current studies failed to support the association between LRP10 and PD in general. Thus, more robust replication studies are warranted to determine the involvement of LRP10 in the pathogenesis of PD. © 2019 International Parkinson and Movement Disorder Society.
