PURPOSE OF THE REVIEW: Jarcho-Levin syndrome is an eponym that has been used to describe a variety of clinical phenotypes consisting of short-trunk dwarfism associated with rib and vertebral anomalies. This admixture of phenotypes under Jarcho-Levin syndrome has allowed some confusion in terms of phenotype, prognosis, and mortality. In the past 2 years, few papers have provided more insight into the clinical diagnosis, prognosis, and management of patient with these phenotypes. RECENT FINDINGS: Recently molecular, clinical, and radiologic data have allowed further characterization of these phenotypes. Based on these findings, we have divided these phenotypes into spondylothoracic dysplasia and spondylocostal dysostosis. SUMMARY: A better understanding of the distinct phenotypes under Jarcho-Levin syndrome will help clinicians to understand the pathological factors of the disease, establish mode of inheritance, provide adequate genetic counseling, prognosis, molecular diagnosis, and clinical management recommendations.
