Abstract
Approximately 20% of aortic aneurysm and/or dissection (AAD) cases result from inherited disorders, including several systemic and syndromatic connective-tissue disorders, such as Marfan syndrome, Ehlers-Danlos syndrome, and Loeys-Dietz syndrome, which are caused by mutations in the FBN1, COL3A1, and TGFBR1 and TGFBR2 genes, respectively. Nonsyndromatic AAD also has a familial background, and mutations of the ACTA2 gene were recently shown to cause familial AAD. In the present study, we conducted sequence analyses of the ACTA2 gene in 14 unrelated Japanese patients with familial thoracic AAD (TAAD), and in 26 with sporadic and young-onset TAAD. Our results identified three mutations of ACTA2, two novel [p.G152_T205del (c.616+1G>T), p.R212Q] and one reported (p.R149C), in the 14 patients with familial TAAD, and a novel mutation (p.Y145C) of ACTA2 in the 26 sporadic and young-onset TAAD patients, each of which are considered to be causative for TAAD. Some of the clinical features of these patients were the same as previously reported, whereas others were different. These findings confirm that ACTA2 mutations are important in familial TAAD, while the first sporadic and young-onset TAAD case with an ACTA2 mutation was also identified.

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
