Periodontal Ehlers-Danlos syndrome

Periodontal Ehlers-Danlos syndrome is an autosomal dominant disorder caused by mutations of the C1R and C1S genes. It is characterized by early-onset periodontitis and teeth loss, joint hypermobility, and mild dermatological findings.


In Ehlers-Danlos syndrome periodontitis is accompanied by typical joint and skin abnormalities.
