Objectives The prevalence of Anderson-Fabry disease (AFD) in patients presenting with unexplained left ventricular hypertrophy (LVH) is controversial.

Inclusion criteria for the study were: men aged at least 35 years and women aged at least 40 years with unexplained LVH (maximum left ventricular wall thickness >= 1.5 cm). All patients were screened using a denaturing high-performance liquid chromatography protocol for rapid mutation screening of the alpha-galactosidase A (alpha-Gal A) gene and, if a sequence variant was found, direct sequencing was performed. 1386 patients (63.9% men, mean age 57.9 +/- 12.0 years) were enrolled in the study. Results Seven (0.5%) patients (age 57.4 +/- 9.0 years (45-72); three (43%) men) had pathogenic alpha-galactosidase A mutations. Polymorphisms were identified in 283 patients (20.4%). Maximal left ventricular wall thickness in patients carrying a disease-causing mutation was 1862 mm (range 15-22); four patients had concentric LVH and the remainder had asymmetric septal hypertrophy.

Abstract

Objectives The prevalence of Anderson-Fabry disease (AFD) in patients presenting with unexplained left ventricular hypertrophy (LVH) is controversial. The aim of this study was to determine the prevalence of AFD in a large, consecutive cohort of patients with hypertrophic cardiomyopathy (HCM) using rapid mutation screening. Design, Setting and Patients A European multicentre cross-sectional study involving 13 referral centres. Inclusion criteria for the study were: men aged at least 35 years and women aged at least 40 years with unexplained LVH (maximum left ventricular wall thickness >= 1.5 cm). All patients were screened using a denaturing high-performance liquid chromatography protocol for rapid mutation screening of the alpha-galactosidase A (alpha-Gal A) gene and, if a sequence variant was found, direct sequencing was performed. 1386 patients (63.9% men, mean age 57.9 +/- 12.0 years) were enrolled in the study. Results Seven (0.5%) patients (age 57.4 +/- 9.0 years (45-72); three (43%) men) had pathogenic alpha-galactosidase A mutations. Polymorphisms were identified in 283 patients (20.4%). Maximal left ventricular wall thickness in patients carrying a disease-causing mutation was 1862 mm (range 15-22); four patients had concentric LVH and the remainder had asymmetric septal hypertrophy. Conclusions The prevalence of AFD gene mutations in a large, consecutive cohort of European patients with unexplained LVH is 0.5%.
