Lethal/severe osteogenesis imperfecta in a large family: a novel homozygous LEPRE1 mutation and bone histological findings.

ABSTRACT

We report a large consanguineous Turkish family in which multiple individuals are affected with autosomal recessive lethal or severe osteogenesis imperfecta (OI) due to a novel homozygous LEPRE1 mutation. In one affected individual histological studies of bone tissue were performed, which may indicate that the histology of LEPRE1 -associated OI is indistinguishable from COL1A1/2 -, CRTAP -, and PPIB -related OI.
