ABSTRACT
Fabry disease is an X-linked lysosomal disease caused by mutations of the alpha-galactosidase A (GLA) gene at chromosome subband Xq22.1. To date, more than 600 genetic mutations have been identified to determine the nature and frequency of the molecular lesions causing the classical and milder variant phenotypes and for precise carrier detection. We report here a Fabry family (mother, son and daughter) where the alpha-galactosidase A defect was associated with a glucose-6-phosphate dehydrogenase (G6PD) deficiency. Mutation analysis revealed for the GLA gene the presence of a new mutation, i.e., a small deletion (c.452delA) on exon 3 and for the G6PD gene the presence of 2 mutations, p.V68M (G6PD Asahi, G6PD A+) and p.N126D (G6PD A+) on exon 3 and exon 4, respectively.
