High Incidence of the Cardiac Variant of Fabry Disease Revealed by Newborn Screening in the Taiwan Chinese Population

Abstract

We found an unexpected high prevalence of the cardiac variant Fabry mutation IVS4+919G-->A among both newborns (approximately 1 in 1600 males) and patients with idiopathic hypertrophic cardiomyopathy in the Taiwan Chinese population. The early identification of undiagnosed patients allows timely therapeutic intervention providing a better clinical outcome.
