Abstract

Anderson-Fabry disease (AFD) is a rare X-linked disorder caused by deficient activity of the lysosomal enzyme α-galactosidase A (α-GAL A). We herein report 10 cases of AFD in 5 families (3 men and 7 women) that were found to have a specific common mutation in R301Q [G-to-A transition in exon 6 (codon 301) resulting in the replacement of a glutamine with an arginine residue]. We evaluated their clinical characteristics, residual enzymatic activity, and plasma concentrations of globotriaosylsphingosine (Lyso-Gb3). Although all 10 cases had cardiac and renal manifestations in common, their clinical manifestations were markedly divergent despite the same genetic abnormality.
