Genetic testing for primary aldosteronism in SPAIN: Results from the SPAIN-ALDO Registry and review of the literature.

The genetic study of familial hyperaldosteronism is often scarce in real-world clinical practice, as 86% of patients with criteria to undergo genetic study were not evaluated in our cohort. Nevertheless, FH is an uncommon cause of PA, representing only 0.2% of cases in the SPAIN-ALDO Registry, although its prevalence may be as high as 4% among suspected cases might be studied.
