We report a unique case with co-occurrence of Turner syndrome and Fabry disease (OMIM #301500). The latter is a rare X-linked lysosomal storage disease that is characterized by partial or complete deficiency of α-galactosidase A (GLA; EC 188.8.131.52) following mutations in the gene (GLA) localized at Xq22.1. Accumulation of metabolic intermediates can occur in many tissues and leads to severe morbidity, especially due to renal failure, cardiac involvement and stroke. It is well established that hemizygous male mutation carriers with Fabry disease are generally more severely affected than heterozygous female mutation carriers, but disabling clinical features and disease progression often occur in female Fabry patients as well. The majority of this patients cells are of the 45,X type, making her a hemizygous GLA mutation carrier displaying a very severe Fabry disease phenotype.
