Item Differences in the Presentation and Progression of Parkinson's Disease by Sex(Wiley, 2021) Iwaki, Hirotaka; Blauwendraat, Cornelis; Leonard, Hampton L.; Makarious, Mary B.; Kim, Jonggeol J.; Liu, Ganqiang; Maple-Grødem, Jodie; Corvol, Jean-Christophe; Pihlstrøm, Lasse; van Nimwegen, Marlies; Smolensky, Luba; Amondikar, Ninad; Hutten, Samantha J.; Frasier, Mark; Nguyen, Khanh-Dung H.; Rick, Jacqueline; Eberly, Shirley; Faghri, Faraz; Auinger, Peggy; Scott, Kirsten M.; Wijeyekoon, Ruwani; Van Deerlin, Vivianna M.; Hernandez, Dena G.; Gibbs, Raphael J.; Day-Williams, Aaron G.; Brice, Alexis; Alves, Guido; Noyce, Alastair J.; Tysnes, Ole-Bjørn; Evans, Jonathan R.; Breen, David P.; Estrada, Karol; Wegel, Claire E.; Danjou, Fabrice; Simon, David K.; Andreassen, Ole A.; Ravina, Bernard; Toft, Mathias; Heutink, Peter; Bloem, Bastiaan R.; Weintraub, Daniel; Barker, Roger A.; Williams-Gray, Caroline H.; van de Warrenburg, Bart P.; Van Hilten, Jacobus J.; Scherzer, Clemens R.; Singleton, Andrew B.; Nalls, Mike A.; Medical and Molecular Genetics, School of MedicineBackground: Previous studies reported various symptoms of Parkinson's disease (PD) associated with sex. Some were conflicting or confirmed in only one study. Objectives: We examined sex associations to PD phenotypes cross-sectionally and longitudinally in large-scale data. Methods: We tested 40 clinical phenotypes, using longitudinal, clinic-based patient cohorts, consisting of 5946 patients, with a median follow-up of 3.1 years. For continuous outcomes, we used linear regressions at baseline to test sex-associated differences in presentation, and linear mixed-effects models to test sex-associated differences in progression. For binomial outcomes, we used logistic regression models at baseline and Cox regression models for survival analyses. We adjusted for age, disease duration, and medication use. In the secondary analyses, data from 17 719 PD patients and 7588 non-PD participants from an online-only, self-assessment PD cohort were cross-sectionally evaluated to determine whether the sex-associated differences identified in the primary analyses were consistent and unique to PD. Results: Female PD patients had a higher risk of developing dyskinesia early during the follow-up period, with a slower progression in activities of daily living difficulties, and a lower risk of developing cognitive impairments compared with male patients. The findings in the longitudinal, clinic-based cohorts were mostly consistent with the results of the online-only cohort. Conclusions: We observed sex-associated contributions to PD heterogeneity. These results highlight the necessity of future research to determine the underlying mechanisms and importance of personalized clinical management.Item Endocrine and Growth Abnormalities in 4H Leukodystrophy Caused by Variants in POLR3A, POLR3B, and POLR1C(The Endocrine Society, 2021) Pelletier, Félixe; Perrier, Stefanie; Cayami, Ferdy K.; Mirchi, Amytice; Saikali, Stephan; Tran, Luan T.; Ulrick, Nicole; Guerrero, Kether; Rampakakis, Emmanouil; van Spaendonk, Rosalina M.

The endocrine and growth abnormalities associated with this disorder have not been thoroughly investigated to date. Objective: To systematically characterize endocrine abnormalities of patients with 4H leukodystrophy. Design: An international cross-sectional study was performed on 150 patients with genetically confirmed 4H leukodystrophy between 2015 and 2016. Endocrine and growth abnormalities were evaluated, and neurological and other non-neurological features were reviewed. Potential genotype/phenotype associations were also investigated. Setting: This was a multicenter retrospective study using information collected from 3 predominant centers. Patients: A total of 150 patients with 4H leukodystrophy and pathogenic variants in POLR3A, POLR3B, or POLR1C were included. Main outcome measures: Variables used to evaluate endocrine and growth abnormalities included pubertal history, hormone levels (estradiol, testosterone, stimulated LH and FSH, stimulated GH, IGF-I, prolactin, ACTH, cortisol, TSH, and T4), and height and head circumference charts. Results: The most common endocrine abnormalities were delayed puberty (57/74; 77% overall, 64% in males, 89% in females) and short stature (57/93; 61%), when evaluated according to physician assessment. Abnormal thyroid function was reported in 22% (13/59) of patients. Conclusions: Our results confirm pubertal abnormalities and short stature are the most common endocrine features seen in 4H leukodystrophy. However, we noted that endocrine abnormalities are typically underinvestigated in this patient population. A prospective study is required to formulate evidence-based recommendations for management of the endocrine manifestations of this disorder.
