Clinical variability of type II sialidosis by C808T mutation
Bibliographic record
Abstract
Sialidosis (McKusick 256550) is an autosomal recessive disorder resulting from mutations in the NEU gene, located in 6p21.3, which leads to deficiency of alpha-N-acetyl neuraminidase (sialidase) activity, causing an accumulation of its substrates, oligosaccharides, in the lysosomes of various organs and tissues and an increased presence in urine and other organic fluids. We present a clinical report of three patients diagnosed for type II sialidosis. The first patient is a 12-year-old boy with the classic infantile form. His sister had a congenital form of sialidosis and died at 20 months of age. The third, nonrelated patient presented shortly after 1 year of age and had borderline cognitive delay at 9 years. All three patients were homozygous for the C808T mutation of the NEU gene. Their ancestors originated from a small area to the east of the city of Seville (Spain), suggesting the existence of a Seville founder mutation.

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.
