The main features of the syndrome are shortness of stature with a spinal abnormality, multiple abnormal vertebral defects, and a small malformed \"fan-like\" or \"crab-like\" rib cage due to posterior fusion and anterior flaring of the ribs, leading to short-trunk dwarfism. The spinal and rib malformations result in a small thoracic cavity, not capable of accommodating the growing lungs, causing thoracic insufficiency resulting in severe cardiac and respiratory complications and frequent chest infections. The diagnosis is based on clinical and radiological findings, characteristic physical appearance, symptoms of thoracic insufficiency, family history, consanguineous parents, skeletal survey, or specialized genetic tests for mutations.
