Barth Syndrome: TAFAZZIN Gene, Cardiologic Aspects, and Mitochondrial Studies—A Comprehensive Narrative Review
Bibliographic record
Abstract
Barth syndrome (BTHS) is inherited through an X-linked pattern. The gene is located on Xq28. Male individuals who inherit the TAFAZZIN pathogenic variant will have the associated condition, while female individuals who inherit the TAFAZZIN pathogenic variant generally do not experience the condition. There are several organs that may be affected, but striking is the cardiological involvement. Cardiovascular disease, which may be the trigger starting the diagnostic procedure in a proband, may include a range of diseases from a severely dilated heart to a hypertrophic heart in the spectrum of anomalies encountered. Left ventricular non-compaction of the heart is also occasionally encountered. This cardiac event may reveal the prognosis of the affected patients. In this narrative review, we highlight the gene’s characteristics, the reactome, the cardiological features of the cardiovascular disease observed in patients affected with BTHS, emphasize the most current studies on BTHS cardiomyopathy, and delineate the biological underlying mechanisms supporting the proposal of new therapeutic options.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
