Genetic variability of the retromer cargo recognition complex in parkinsonism
Bibliographic record
Abstract
BACKGROUND: A pathogenic mutation (VPS35 p.D620N) within the retromer complex has been shown to segregate with late-onset Parkinson's disease (PD). Several studies have subsequently detected the mutation in patients with PD and not in controls. METHODS: Mutation screening of the coding regions of the retromer cargo recognition complex genes (VPS26A/B, VPS29, and VPS35) was carried out in patients with PD (n = 396), atypical parkinsonism (n = 229), and in 368 controls. RESULTS: Overall, we identified five rare nonsynonymous mutations in VPS26A and one in VPS35; none were observed in VPS26B or VPS29. Three VPS26A variants (p.K93E, p.M112V, and p.K297X), identified in patients with atypical parkinsonism, were not observed in controls from this study (n = 368) or from publically available data sets (n = 4,426). CONCLUSION: Our results support the hypothesis that rare variants in the retromer complex genes may be involved in the development of parkinsonism, although further studies are warranted before any solid conclusions can be drawn.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
