Osteogenesis imperfecta type IIC presents with varying thickness of the ribs, discontinuous beading of the ribs, malformed scapula and ischia, and long bones with thin shafts and expanded metaphyses. Type IIC is extremely rare. Appearances have been reported in fetuses with mutations in the MESD gene (15q25). The disease is either autosomal dominant or autosomal recessive depending on the gene involved. Autosomal dominant cases occur either sporadically or due to germline mosaicism. [from
