Reproductive life factors and estro-progestin exposure in women with early-onset Parkinson's disease compared to late-onset disease and controls: A retrospective cohort study.

Background: Parkinson's disease (PD) is more common in men than women. Although hormonal factors may partially explain this difference, there are no studies evaluating reproductive life factors and exogenous estroprogestin exposure in women with Early Onset Parkinson Disease (EOPD).

Objective: To compare reproductive life factors and exogenous estroprogestin exposure among female patients with EOPD, late-onset Parkinson's disease (LOPD), and EOPD-matched unaffected controls.

Novel RAB39B loss-of-function mutation in patient with typical early-onset Parkinson's disease.

RAB39B mutations have been identified in X-linked developmental delays. Recently, RAB39B mutations were identified in males with early-onset parkinsonism and intellectual disability. A novel loss-of-function RAB39B mutation was found in a female patient with typical early-onset Parkinson's disease (EOPD).
