Brief Summary

The cardiac variant of the Fabry disease is a rare cardiomyopathy affecting 1/50000 individuals in general population. It is generally diagnosed in advanced stages of the disease, because it presents clinical features very similar to the hypertrophic cardiomyopathy ones, making difficult the correct diagnosis. In Fabry disease there is a remodeling process of the myocardial interstitium and apoptosis of myocytes which leads to fibrosis development and later systolic dysfunction. The investigators propose to evaluate the utility of several biomarkers in the diagnosis of this cardiomyopathy, to facilitate the early diagnosis, which is clue to establish early enzyme replacement therapy or intensify the patients' follow up. In order to achieve this objective, the investigators will analyze markers of endothelial dysfunction, fibrosis and apoptosis in peripheral blood samples of patients carrying the mutation but without clinical manifestations and the investigators will compare their levels with dose obtained from two different control groups: diagnosed patients presenting clinical manifestations or index cases and healthy controls without carrying the mutation.

This task will be performed at the monographic hypertrophic cardiomyopathy clinic. The investigators intention is to include 12 families for testing the biomarkers elevation correlation with the presence of disease. The investigators plan to achive the inclusion of 30 families with Fabry diagnosed probands, including up to 130 relatives for verification and the polimorfisms' study.

You may qualify if:

  • families with Fabry diagnosed probands, including up to 80 relatives.
