DISCLAIMER
In general 70% of sSMC carriers are clinically normal. The figures listed above

are based on the bias, that mainly clinically aberrant cases are studied and reported in literature!

Patient born after a pregnancy complicated by severe polyhydramnion. No invasive prenatal diagnostics was done. Delivery was by Caesarean because of fetal distress at 37 weeks gestation. Birth weight 2,500 g (10th centile), OFC 34.8 cm (50th centile), and APGAR scores were 5 and 6 at 1 and 5 min, respectively. At birth profoundly hypotonic with reduced respiratory effort and required positive pressure ventilation. On examination, thorax small and bell shaped. Chest X-ray demonstrated lung hypoplasia, a ‘coat hanger’ shape of the ribs and elongated clavicles. There was stippled premature ossification of the proximal humeral epiphyses. She had a marked scoliosis convex to the[nbsp] right. Palpebral fissures were short. There were contractures of the wrists with ulnar deviation bilaterally, second digit extensor contractures and swan neck deformity of third and fourth digits bilaterally. She had a prominent forehead with an elongated philtrum, a midline tubercle of the upper lip vermilion, and a broad flat nasal bridge with anteverted nares. She had an H-shaped pattern of creases under the lower lips reminiscent of the Freeman-Sheldon syndrome. Skull X-ray revealed a hypoplastic maxilla and mandible and a small anterior fossa. There was diastasis of the recti and significant hepatomegaly. She developed severe pulmonary hypertension with right heart enlargement and a large patent ductus on day 2 of life, required continuous positive airways pressure until day 43 and had supplemental oxygen therapy after discharge at a variable flow of 100-250 ml/min. She required nasogastric tube feeding due to a poor swallowing reflex and inadequate airway protection, and regular oropharyngeal suction was necessary. She developed recurrent episodes of pneumonia and died of respiratory failure secondary to a respiratory infection at age 5 months. Autopsy demonstrated architecturally and cytological normal skeletal muscle, skin, liver, and nerves.
