N-Glycanase 1 Deficiency Is a Rare Cause of Pediatric Neurodegeneration With Neuronal Inclusions and Liver Steatosis
Bibliographic record
Abstract
Pediatric neurodegeneration is extremely rare and devastating to the families involved. We describe a rare case of pediatric neurodegeneration in a child with N-glycanase 1 (NGLY1) deficiency. This child had an autosomal recessive mutation in NGLY1, the gene coding for the enzyme NGLY1 that was found with exome sequencing. NGLY1 catalyzes protein deglycosylation by cleaving the -aspartyl glycosylamine bond of N-linked glycoproteins and is thereby a component of the endoplasmic reticulum-associated degradation pathway. This child passed away at five years of age after a prolonged clinical course with myoclonic epilepsy, choreoathetosis-like movements, lacrimal duct problems, and severe developmental delay. This autopsy case report shows images of the neuronal inclusions and liver steatosis found in this patient with NGLY1 deficiency and offers a detailed clinical history.

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.
