Abstract
Terminal limb deficiency defects affect between three and eight babies per 10000 births and are an important cause of disability. Established causes for these malformations include single gene disorders, chromosome abnormalities, teratogens, and amniotic bands. However, the etiology remains unknown in a significant proportion of cases. Several authors have hypothesized that vascular accidents, either bleeds or vessel occlusions, may underlie a substantial number of cases; but, for the most part, the origin of such events remains obscure. Over the past several years, an increasing number of genetic thrombophilias have been recognized and have been associated with increased risks of peri- and post-natal occlusive disease, and with higher rates of recurrent pregnancy loss. The hypothesis to be examined in this pilot study was whether the inherited thrombophilias might be associated with a vascular cause of some terminal limb deficiency defects. Towards that end, protein C, protein S, antithrombin III, factor V Leiden mutation, prothrombin (G20210A) variant, methylenetetrahydrofolate reductase variant, plasma homocysteine, anticardiolipin IgM and IgG antibodies, and lipoprotein (a) were measured in 24 mother-child pairs in which the child had a terminal limb defect. The results provided some evidence that there may be an excess of thrombophilias present in such families and that they may play some etiological role in a subset of these types of limb malformations.

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
