✦ Synopsis

Fabry disease, an X-linked recessive disorder of glycosphingolipid catabolism, results from lesions in the alpha-galactosidase A gene leading to deficient or absent activity of the lysosomal hydrolase. To facilitate the detection of rearrangements in this 14-kb gene, a method was developed for the PCR amplification of all seven exons from genomic DNA in a single multiplex reaction. The entire coding region and all the intron/exon boundaries were amplified as four products. Application of this method permitted the detection of all five partial deletions previously identified by Southern analysis. This rapid method can be used to identify gene rearrangements in affected hemizygotes and determine heterozygosity for at risk females in families with Fabry disease.

Fabry disease is an X-linked recessive lysosomal storage disorder caused by a deficiency of a-galactosidase A (a-gal; EC 3.2.1.22). In the past, it has been difficult to give an unequivocal diagnosis of carrier status in Fabry disease because of the overlap between normal and heterozygote enzyme lev

We found a novel acceptor splice site mutation in the invariant AG of intron 6 of a-galactosidase A (a-Gal A) gene (IVS6-1G->A) in a patient with Fabry disease by sequencing of genomic DNA. Sequencing of RT-PCR revealed the deletion of first base pair (c909del) of exon 7 in mRNA and a frameshift res
