Abstract
Mucopolysaccharidosis III type C is a lysosomal storage disorder caused by the accumulation of heparan sulfate in lysosomes. The disorder occurs due to Heparan Acetyl-CoA: α-glucosaminide N-acetyltransferase (HGSNAT) deficiency, an enzyme which typically catalyzes the transmembrane acetylation of heparan sulfate, a basement membrane component. When the gene encoding this enzyme is mutated, it cannot perform the processing of heparan sulfate, leading to un-acetylated heparan sulfate build-up in the lysosomes of cells, causing a storage disorder. This defect has been studied primarily in brain and liver cells, but its effect on the structural integrity of the glomerulus is poorly known. The present study focuses on the effect of Hgsnat gene inactivation and heparan sulfate toxicity on the integrity of the renal corpuscle. This cortical structure was chosen because of its abundance of basement membranes and heparan sulfate as well as the renal corpuscle's physiological importance in glomerular filtration. Light microscopy, electron microscopy, and immunocytochemistry of genetically modified mice revealed a buildup of lysosomes in the podocytes, suggesting that these cells are responsible for the processing of glomerular basement membranes.

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
