Data were expressed as mean (standard deviation) for continuous variables, and as counts (percentages) for categorical variables. We used t-tests to compare the two groups for continuous variables and Fisher’s exact tests for binary variables. Coefficients for continuous clinical features and odds ratios for binary clinical features and standard error (SE), Cohen’s f2 and p-values were calculated from GLMs with mutation status, sex, age at onset, disease duration, L-DOPA group and age at onset vs disease duration for all 15 variables except for onset variables for which only mutation status, sex and age-at-onset were added. Linear models were used for continuous variables; GLMs with logit links and Bernoulli distributions were used for binary variables; UPDRS III, the motor subsection of the Unified Parkinson’s Disease Rating Scale.

Levodopa responsiveness was defined as a >30% improvement in subjective perceived motor symptoms.

Uncertain Spans

  • Upper PRKN variant table headers are not visible in this crop; the reconstructed table preserves visible cells only.
  • Several rsID and transcript strings in the upper PRKN variant table are taken from crop-level OCR plus visual confirmation where legible; faint or cropped cells are left blank.
  • Row-level right-side counts and consequence labels in the AMP-PD slide are too small to verify fully; aggregate rows are visually legible and retained.
  • Superscript footnote letters in the article table are visible but not consistently legible; numeric values are retained without superscript letters where uncertain.
