Abstract
Adult Refsum disease is a rare hereditary peroxisomal disorder characterized by impaired phytanic acid metabolism. The accumulation of phytanic acid in tissues, especially adipose and neural, is believed to contribute to disease manifestations. Clinically apparent kidney dysfunction has been reported in only 2 cases. We describe a 55-year-old woman with adult Refsum disease, who was referred to nephrology for impaired kidney function without proteinuria. Kidney biopsy showed vacuolization of proximal tubular epithelium and unremarkable glomeruli. Focally, distal tubular cytoplasm showed variably sized crystals with ultrastructural laminated substructures (or "paracrystalline formation"). To the best of our knowledge, the light microscopy for these crystals in a peroxisomal disease has not been previously described, and adult Refsum disease has not been described as a significant metabolic kidney disorder. These unique morphologic features contribute to the spectrum of findings in this rare genetic condition. This case also demonstrates the value of kidney function monitoring and therapeutic plasma exchange for these patients.

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 it
