Ehlers-Danlos syndrome (EDS), hypermobility type, is probably the most common EDS type, as well as the most common heritable connective tissue disorder. Bladder dysfunction is a rare clinical manifestation of EDS and manifests itself as primary nocturnal enuresis. We present a 10-year-old boy referred to the paediatrics nephrology consultation due to primary nocturnal enuresis and day time symptoms of urinary urgency. During the appointment, a tendency to joint hypermobility was noted. On evaluation the skin was hyperextensible and the Beighton score was positive. The genetic testing revealed a variant of the COL5A1 gene not yet described in the literature.
