Mutation analysis of alpha-galactosidase a gene in Hungarian Fabry patients.

UNLABELLED: AIM was to detect the mutations of alpha-galactosidase A gene in two Hungarian Fabry patients. METHODS: Mutation analysis was performed by polymerase chain reaction (PCR) sequencing of the seven exons and adjacent introns of the alpha-galactosidase A gene. RESULTS: Case 1. (19 y. male patient) Mutation analysis was done for alpha-galactosidase gene, a missence mutation has been identified in the 5th exon, the aspartic acid at codon 266 has been substituted by a tyrosine (notation D266Y) due to a G-T transversion at position 10287 of the alpha GAL-A gene. Case 2. (28 y. male Fabry patient) The GAL-A mutation has been proven to be R220X mutation in exon 5 of the alpha-galactosidase A gene.
