Abstract
Sideroblastic anemias are a heterogeneous group of disorders, characterized by mitochondrial iron overload in developing red blood cells. The unifying characteristic of all sideroblastic anemias is the ring sideroblast, which is a pathological erythroid precursor containing excessive deposits of non-heme iron in mitochondria with perinuclear distribution creating a ring appearance. Sideroblastic anemias may be hereditary or acquired. Hereditary sideroblastic anemias are caused by defects in genes present on the X chromosome (mutations in the ALAS2, ABCB7, or GRLX5 gene), genes on autosomal chromosomes, or mitochondrial genes. Acquired sideroblastic anemias are either primary (refractory anemia with ring sideroblasts, RARS, representing one subtype of the myelodysplastic syndrome) or secondary due to some drugs, toxins, copper deficiency, or chronic neoplastic disease. The pathogenesis of mitochondrial iron loading in developing erythroblasts is diverse. Ring sideroblasts can develop as a result of a heme synthesis defect in erythroblasts (ALAS2 mutations), a defect in iron-sulfur cluster assembly, iron-sulfur protein precursor release from mitochondria (ABCB7 mutations), or by a defect in intracellular iron metabolism in erythroid cells (e.g. RARS).

Full frame distilled prediction
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
