Osteogenesis imperfecta IIC caused by a novel heterozygous mutation in the C-propeptide region of COL1A1.

ABSTRACT: Osteogenesis imperfecta IIC (OI IIC), which is a rare variant of lethal OI that has been considered to be an autosomal recessive trait, is characterized by twisted, slender long bones with dense metaphyseal margins. Here, we report a typical case of OI IIC caused by a novel heterozygous mutation in the C-propeptide region of COL1A1. OI IIC seems to be caused by a dominant mutation of COL1A1.
