| Sumario: | Dysostosis spondylothoracic, or Jarcho Levin syndrome, is characterized by a short neck and thorax, a protruding abdomen, abnormal vertebral segmentation and fusion posterior costal resulting in thoracic restriction or respiratory failure and scoliosis. The prevalence is
estimated at 1 in 12,000 live births for the people of Puerto Rico and 1 per 200,000 for the rest of the world. It is inherited in an autosomal recessive manner and the only related gene is MESP2. Clinical case: Newborn male, who during the first hour of life develops perioral cyanosis, thoracoabdominal dissociation and polipnea, requiring endotracheal intubation and mechanical
ventilation for respiratory impairment, finding thoracoabdominal costovertebral abnormalities with an x-ray, and a conditioning restrictive pattern like a crab. During the physical examination, we found horizontal eyelid openings, right atrial appendage, straight nasal bridge, short thorax and asymmetry and hypertrichosis, predominantly in the back. A diagnosis of dysostosis
spondylothoracic is confirmed, and the patient was discharged at 7 days of age, with follow up
neonatal consultation at high risk.
