Features include very common findings: Increased bone density (increased bone mineral density); and common findings: Sideways curvature of the spine (scoliosis), Excessive outward curvature of the upper spine (kyphosis), Abnormal form of the vertebral bodies, and Sclerotic vertebral body. 9 total HPO annotations.
