Abstract

fetched live from OpenAlex

BACKGROUND: Erythropoietic protoporphyria (EPP) is known to be inherited in both autosomal dominant and recessive manners. A deleterious mutation in conjunction with a polymorphic wild type allele underlies the molecular basis of the dominant type. METHODS: We report a patient with EPP who was found to have a novel large deletion [c.1-9628_67+2871del12566 bp] and three polymorphisms [c.1-251A>G, c.68-23C>T and c.315-48T>C] in trans to the deletion in his ferrochelatase (FECH) gene. RESULTS: The combination of the deletion and the polymorphisms reduced his FECH activity level to 20% of control. CONCLUSIONS: It is conceivable that a homozygous state for this polymorphic haplotype might be sufficient to produce clinical phenotype of EPP. The boundary between autosomal dominant and autosomal recessive inheritance may not always be distinct.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Teacher imitation

Not 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.
