Fabry nephropathy: a treatable cause of chronic kidney disease
Bibliographic record
Abstract
Fabry disease is a rare X-linked inborn error of metabolism that has a high prevalence of chronic kidney disease (CKD) and renal failure. It is due to the deficiency of the α-galactosidase A (α-Gal) lysosomal enzyme with subsequent accumulation of globotriaosylceramide (Gb3) in lysosomes. In the kidney, the podocyte is the main target of this disease, although all cell types are involved. The podocyte, being terminally differentiated, does not replicate and thus accumulates Gb3 throughout life. Podocytes are injured by Gb3, leading to their detachment from the glomerular basement membrane and subsequent loss in the urine. Albuminuria starts in childhood and progresses to overt proteinuria in the teens and 20 s. CKD ensues with adults starting dialysis at an average age of 42 years. Patients have a high prevalence of stroke and cardiomyopathy with hypertrophic change, heart failure, and dysrhythmias. Patient survival is limited in both genders. Diagnosis is based on the demonstration of a low α-Gal activity and a pathogenic GLA mutation. Clinical features are highly variable, which makes recognition of this condition difficult. Treatment with intravenous recombinant human enzyme replacement therapy (ERT) and oral pharmacologic chaperone are available. Control of proteinuria to 0.5 g/day or less is of critical importance to limit progression to end-stage renal disease. Early initiation of treatment gives the best results, but the optimal age to start is uncertain. Fabry nephropathy remains a challenge due to its multisystem nature, difficult diagnosis, and complicated management. It is important as a treatable cause of CKD.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
