Osteogenesis imperfecta (OI) type I is caused by a reduction of type I collagen resulting from the presence of a non-functional COL1A1 allele (null-allele). Owing to the lack of mutant mRNA, genomic screening of the COL1A1 and COL1A2 genes is required to identify a causal mutation, which is a costly
In general, osteogenesis imperfecta is caused by heterozygous mutations in either of the genes encoding the alpha 1 or alpha 2 chains of type I collagen (COL1A1 and COL1A2, respectively). Usually, these mutations are unique to the affected individual or individuals within a family. In this study, si
