Osteogenesis imperfecta

This Was Not Photoshopped

This is osteogenesis imperfecta or “brittle bone disease,” an autosomal dominant inherited connective tissue disorder due to mutation in type I collagen (COL1A1, COL1A2). Type I collagen is found in bone, tendon, ligament, skin, and sclera. Bone histology shows more disorganized woven bone. Clinical manifestations include excess or atypical fractures, short stature, scoliosis, basilar skull deformities, blue sclera (seen here), hearing loss, opalescent teeth that wear quickly (dentinogenesis imperfecta), increased laxity of ligaments and skin, small irregular bones along cranial structures, and increased bruising.
