Introduction: Runt-related transcription factor 2 (RUNX2) is a major transcription factor essential for the regulation of osteoblast and chondrocyte differentiation, hence affecting skeletogenesis, bone and cartilage formation. The RUNX2 protein has unique consecutive polyglutamine and polyalanine repeats (Q/A) which are important for its transactivation function. Several variants within the RUNX2 gene have been implicated in osteoporosis and fracture susceptibility.<...
