Osteogenesis imperfecta/ Ehlers-Danlos overlap syndrome (COL1-related disorder) and pregnancy.

Ehlers-Danlos syndrome is in a group of connective tissue disorders that can result in a range of complications during pregnancy. Clinical manifestations include skin hyperextensibility, atrophic scarring, poor wound healing, hyperflexibility or higher risk of organ ruptures (uterine rupture, aortal dissection). The combination of Ehlers-Danlos syndrome and osteogenesis imperfecta is very rare (< 1/1,000,000 according to Orphanet). We are presenting a case of woman with osteogenesis imperfecta/Ehlers-Danlos overlap syndrome and her pregnancy complicated by aortal dilatation. Our case has attempted to highlight the potential obstetric complications and to attract the attention of clinical physicians to the rare but extremely dangerous syndrome.
