However, it is unclear whether lyso-Gb3 is elevated in patients with later-onset Fabry disease. Thus, we measured lyso-Gb3 levels from dried blood spots (DBS) from male newborns with the Fabry disease later-onset phenotype, IVS4+919G>A mutation, and their family members. The lyso-Gb3 levels were below the detection limit in normal control newborns and were slightly higher in adults. In males of all ages with the IVS4+919G>A mutation, lyso-Gb3 levels were elevated and were higher than in age-matched controls. The elevation of lyso-Gb3 levels in males with the IVS4+919G>A mutation was only slightly elevated compared with patients with the classical Fabry phenotype. The measurement of lyso-Gb3 levels is useful in the diagnosis of Fabry disease, including the later-onset phenotype. The DBS lyso-Gb3 level was not elevated in IVS4+919G>A heterozygotes, and is not useful for their diagnosis. Since lyso-Gb3 levels are elevated from birth in Fabry disease males, "an elevated lyso-Gb3 level" may be of little values for deciding when to begin enzyme replacement therapy. ? 2012 SSIEM and Springer Science+Business Media Dordrecht. |
