Fabry disease (FD) is an X-linked genetic condition caused by variants in the GLA gene causing enzyme α-galactosidase A deficiency and accumulation of globotriaosylceramide (Gb3) in tissues such as the heart, kidneys, and the nervous system. This study reports a case series of patients with FD, highlighting the phenotypic diversity of the disease, which can be confused with other cardiological conditions. When properly indicated, genetic evaluation, combined with biomarker dosage and α-galactosidase enzymatic activity, is key for an accurate diagnosis. Early diagnosis of FD is fundamental for initiating treatments that can slow disease progression and prevent serious complications, reinforcing the need for greater awareness about this condition among cardiologists.
