Kenro Kusumi, Ph.D., is an Associate Professor in the School of Life Sciences at Arizona State University and is a founding faculty member at the new University of Arizona College of Medicine-Phoenix in partnership with Arizona State University. Dr. Kusumi's current research focuses on early spinal development, axial musculoskeletal regeneration, and their applications to genetic studies of scoliosis and other musculoskeletal disorders.
Sally L. Dunwoodie, Ph.D., is an Associate Professor at the University of New South Wales and Laboratory Head in the Developmental Biology Division at the Victor Chang Cardiac Research Institute in Sydney. Dr Dunwoodie's research focuses on development of the spine, heart, kidney and placenta in mouse, and their relevance to the molecular basis of congenital abnormalities.
Scoliosis is a heterogeneous group of spinal curvature disorders that are frequently encountered by health professionals (estimated to affect 2-3% of the population). Patients are concerned about prognosis, associated health conditions and recurrent risks. Developmental genetic studies of the spine and linkage and family-based association studies have led to recent advances in understanding the genetic etiology of idiopathic, neuromuscular, and congenital forms of scoliosis. The book is written by leaders in genetic and developmental research on scoliosis and developmental studies of the spine. Recent developments in clinical and molecular genetic studies of these disorders are also discussed.
