Abstract
Individuals affected by restrictive cardiomyopathy (RCM) often develop heart failure at young ages resulting in early heart transplantation. Familial forms are mainly caused by mutations in sarcomere proteins and demonstrate a common genetic etiology with other inherited cardiomyopathies. Using next-generation sequencing, we identified two novel missense variants (p.S1624L; p.I2160F) in filamin-C (FLNC), an actin-cross-linking protein mainly expressed in heart and skeletal muscle, segregating in two families with autosomal-dominant RCM. Affected individuals presented with heart failure due to severe diastolic dysfunction requiring heart transplantation in some cases. Histopathology of heart tissue from patients of both families showed cytoplasmic inclusions suggesting protein aggregates, which were filamin-C specific for the p.S1624L by immunohistochemistry. Cytoplasmic aggregates were also observed in transfected myoblast cell lines expressing this mutant filamin-C indicating further evidence for its pathogenicity. Thus, FLNC is a disease gene for autosomal-dominant RCM and broadens the phenotype spectrum of filaminopathies.

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
