'''Fabry disease''' is a rare X-linked [[lysosomal storage disease]] that leads to [[renal failure]]. | |||
==General== | |||
*Rare X-linked genetic disease. | |||
**Caused by defect in ''alpha-galactosidase A gene'' (''GLA gene'').<ref name=omim301500>{{OMIM|301500}}</ref> | |||

===Presentation=== | |||
*Women: usually proteinuria. | |||
*Men: [[angiokeratoma]]s, proteinuria. | |||
===Tx=== | |||
