✦ Synopsis
Clinical Data on Patients
KO was 35 years of age at the time her cell strain was sent to us. She was born to healthy unrelated parents and has two healthy siblings, both of whom have unaffected children, and no other individuals with 0 1 were identified in the family. She had many fractures at birth and continued to fracture periodically. At the age of 35 she was 94 cm tall, walked with the help of a cane, and had slightly blue sclerae and diminished hearing.
PJ was identified as having skeletal anomalies in utero at 15 weeks gestation when short limbs were detected. X-rays taken in the perinatal period demonstrated diminished calvarial mineralisation but no wormian bones, thin cortices of all long bones, marked bowing of both femurs, recent fracture of the right humeral shaft, narrow thoracic cage, but no acute or healing rib fractures. By age 5 years he was not able to walk due to multiple and recurrent

Osteogenesis imperfecta (OI) is a generalized disorder of connective tissue characterized by fragile bones and easy susceptibility to fracture. Most cases of OI are caused by mutations in type I collagen. We have identified and assembled structural mutations in type I collagen genes (COL1A1 and COL1
