Spinal muscular atrophy and Ehlers-Danlos syndrome : a rare association.

Ehlers-Danlos Syndrome (EDS) is a group of heritable connective tissue disorders characterised by hyperelasticity of the skin and hypermobile joints. In addition to those features it is often associated with many systemic complications. Though many neurological complications have been described, an association of spinal muscular atrophy (SMA) has not been reported. We are reporting this rare association - a case of EDS with Kugelberg-Welander disease (type III SMA).
