Identification of a COL1А2 deletion in exon 50 in a 2nd trimester fetus with osteogenesis imperfecta type 2

https://doi.org/10.1234/XXXX-XXXX-2016-8-18-21

Abstract

A case of osteogenesis imperfecta type 2 in a 20 weeks fetus aborted after prenatal diagnosis is reported. Prenatal diagnosis was verified after termination of pregnancy. Molecular analysis by multiplex ligation-dependent probe amplification revealed a COL1А2 deletion in exon 50.
