Seven unrelated patients with atypical variants of hemizygous Fabry's disease were found among 230 men with left ventricular hypertrophy (3 percent). Fabry's disease should be considered as a cause of unexplained left ventricular hypertrophy.

The clinical spectrum of Fabry disease includes a "renal variant" phenotype in patients without classic symptoms who develop ESRD. Affected males undergoing hemodialysis or renal transplantation can be readily diagnosed by plasma alpha-Gal A assays. These patients and their family members may benefit from enzyme replacement therapy for the later, life-threatening cardiovascular and cerebrovascular complications of Fabry disease.
