    Genetic Testing for Parkinson Disease: Are We Ready?
    (American Academy of Neurology, 2021-02) Cook, Lola; Schulze, Jeanine; Kopil, Catherine; Hastings, Tara; Naito, Anna; Wojcieszek, Joanne; Payne, Katelyn; Alcalay, Roy N.; Klein, Christine; Saunders-Pullman, Rachel; Simuni, Tatyana; Foroud, Tatiana; Medical and Molecular Genetics, School of Medicine
    Purpose of review: With the advent of precision medicine and demand for genomic testing information, we may question whether it is time to offer genetic testing to our patients with Parkinson disease (PD). This review updates the current genetic landscape of PD, describes what genetic testing may offer, provides strategies for evaluating whom to test, and provides resources for the busy clinician. Recent findings: Patients with PD and their relatives, in various settings, have expressed an interest in learning their PD genetic status; however, physicians may be hesitant to widely offer testing due to the perceived low clinical utility of PD genetic test results. The rise of clinical trials available for patients with gene-specific PD and emerging information on genotype-phenotype correlations are starting to shift this discussion about testing. Summary: By learning more about the various genetic testing options for PD and utility of results for patients and their care, clinicians may become more comfortable with widespread PD genetic testing in the research and clinical setting.

    International Genetic Testing and Counseling Practices for Parkinson's Disease
    (Wiley, 2023) Saunders-Pullman, Rachel; Raymond, Deborah; Ortega, Roberto A.; Shalash, Ali; Gatto, Emilia; Salari, Mehri; Markgraf, Maggie; Alcalay, Roy N.; Mascalzoni, Deborah; Mencacci, Niccolò E.; Bonifati, Vincenzo; Merello, Marcelo; Chung, Sun Ju; Novakovic, Ivana; Bardien, Soraya; Pal, Gian; Hall, Anne; Hattori, Nobutaka; Lynch, Timothy; Thaler, Avner; Sue, Carolyn M.; Foroud, Tatiana; Verbrugge, Jennifer; Schulze, Jeanine; Cook, Lola; Marder, Karen; Suchowersky, Oksana; Klein, Christine; Simuni, Tatyana; Medical and Molecular Genetics, School of Medicine
    Background: There is growing clinical and research utilization of genetic testing in Parkinson's disease (PD), including direct-to-consumer testing. Objectives: The aim is to determine the international landscape of genetic testing in PD to inform future worldwide recommendations. Methods: A web-based survey assessing current practices, concerns, and barriers to genetic testing and counseling was administered to the International Parkinson and Movement Disorders Society membership. Results: Common hurdles across sites included cost and access to genetic testing, and counseling, as well as education on genetic counseling. Region-dependent differences in access to and availability of testing and counseling were most notable in Africa. High-income countries also demonstrated heterogeneity, with European nations more likely to have genetic testing covered through insurance than Pan-American and Asian countries. Conclusions: This survey highlights not only diversity of barriers in different regions but also the shared and highly actionable needs for improved education and access to genetic counseling and testing for PD worldwide. © 2023 International Parkinson and Movement Disorder Society.
