Mature hypotrophic newborn with very soft, elongated calvarium (Caput papyraceum), atypical horizontally oriented skinfolds along the upper and lower extremities.
Decreased concentration of the serum alkaline phosphatase.
Intubation and ventilation necessary due to increasing respiratory insufficiency. Exitus letalis at the day 15 due to respiratory insufficiency.  

Decreased activity of the isoenzymes of alkaline phosphatase produced in the liver, cartilage and bone.
Therefore mineralization disturbance of the osteoid with misrelation between mineralized and unmineralized osteoid.
