ObjectivesTo evaluate the nature of the molecular lesions in the alpha-galactosidase A gene of two patients having Fabry disease.MethodsEnzyme analyses were done using 4-methylumbellyferyl alpha-galactoside as substrate. Single stranded conformational polymorphism analysis and DNA sequencing were performed following PCR amplification of seven exons of alpha-galactosidase A gene.ResultsTwo new mutations, M11V and R190X, were identified. The female patient with M11V mutation had rheumatologic symptoms, microalbuminuria. The male patient with R190X mutation had a classical phenotype. M11V mutation is in the signal sequence of the peptide and may affect the targeting of the ribosomes to ER. R190X mutation causes premature termination, and probably leads to degradation of the protein.ConclusionThis is the first study in our country investigating the molecular aspects of Fabry disease. It provides the molecular basis for understanding the underlying mechanism of Fabry disease, allows prenatal diagnosis and provides genotype/phenotype correlations.
