To increase the precision of the diagnosis of osteogenesis imperfecta (OI), we used HRM to explore COL1A1/COL1A2 mutations in 87 Chinese OI patients and to perform population-based studies of the relationships between their genotypes and phenotypes.

Osteogenesis imperfecta (OI) is a heritable connective tissue disorder that most often arises from type I collagen-COL1A1 and COL1A2-gene defects leading to skeletal fragility, short stature, blue-gray sclera, and muscle weakness.

The large majority of individuals with an OI phenotype have disease-causing dominant variants in COL1A1 or COL1A2, the genes coding for collagen type I. Interestingly, large sequencing databases indicate that there are about 10 times more carriers of COL1A1/COL1A2 variants that should lead to OI than there are individuals with a diagnosis of OI.
