Abstract
Anderson-Fabry disease is an X-linked lysosomal storage disorder due to α-galctosidase A deficiency. In affected males there is a high mortality in early adult life due to renal failure and cardiovascular complications. We describe our preliminary results from genetic linkage studies in five families using two polymorphic DNA probes, DXS17 and DXYS1, mapping to an area on the long arm of the X chromosome between Xq13–22. DXS17 identified a Taql polymorphism closely linked to the disease locus in three families (lodmax Z=4.23. at a recombination fraction ↓ ⊝=0.0). Restriction fragment length polymorphisms detected by DXYS1 were not linked.Keywords
