Aortic and arterial manifestations and clinical features in <i>TGFB3</i>-related heritable thoracic aortic disease: results from the Montalcino Aortic Consortium
Bibliographic record
Abstract
Background Pathogenic variants in TGFB3 may lead to a syndromic genetic aortopathy. Heritable thoracic aortic disease (HTAD) and arterial events may occur in TGFB3 -related disease but there are limited outcomes data on vascular events in this condition. Methods Clinical data, phenotypical features and aortic outcomes in individuals with pathogenic/likely pathogenic (P/LP) TGFB3 variants enrolled in the Montalcino Aortic Consortium registry were reviewed. Results 34 individuals (56% male, median age 42 years, IQR 17–49, range 3–74 years) with P/LP TGFB3 variants were studied. Craniofacial, cutaneous and musculoskeletal features seen in Loeys-Dietz syndrome were variably present. Extra-aortic cardiovascular features included arterial tortuosity (25%), extra-aortic arterial aneurysms (6%) and mitral valve prolapse (21%). Aortic dilation (Z-Score>2) was present in 10 individuals (29%) and aortic dissection occurred in 2 (6%). Type A aortic dissection occurred in two patients (aged between 55 years and 60 years), and one of these patients experienced a type B aortic dissection 6 years later. Seven adults (median age 62 years, range 32–69 years) with aortic root dilation (41–49 mm) are being followed. No patients have undergone prophylactic aortic surgery. Twenty-five per cent of children have aortic dilation. Sixty-eight per cent of the entire cohort remains free of aortic disease. No deaths have occurred. Conclusions TGFB3 -related HTAD is characterised by late-onset and less penetrant thoracic aortic and arterial disease compared with other transforming growth factor β HTAD. Based on our data, a larger aortic size threshold for prophylactic aortic surgery is appropriate in patients with TGFB3 -related HTAD compared with HTAD due to TGFBR1 or TGFBR2 variants.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
