| 618188 | OMIM | Hyperparathyroidism, transient neonatal (HRPTTN) | An autosomal recessive disease characterized by impaired transplacental maternal-fetal transport of calcium, high serum PTH levels and signs of metabolic bone disease in the neonatal period. Skeletal anomalies include generalized osteopenia, narrow chest, short ribs with multiple healing fractures, and bowing or fractures of long bones. Affected individuals experience postnatal respiratory and feeding difficulties. The condition improves within a short time after birth once calcium is provided orally.
