Identification of gene mutation in patients with osteogenesis imperfect using high resolution melting analysis.

ABSTRACT: Osteogenesis imperfecta (OI), a congenital bone disorder, is caused by mutations in COL1A1 and COL1A2 genes, leading to deficiency of type I collagen. The high resolution melting (HRM) analysis has been used for detecting mutations, polymorphisms and epigenetic alteration in double-stranded DNAs. This study was to evaluate the potential application of HRM analysis for identifying gene mutations in patients with OI. This study included four children with OI and their parents and fifty normal people as controls. Blood samples were collected for HRM analysis of PCR-amplified exons and flanking DNA sequences of COL1A1 and COL1A2 genes. Direct gene sequencing was performed to validate HRM-identified gene mutations. As compared to controls, HRM analysis of samples form children with OI showed ab
