متن کاملPrenatal genetic diagnosis of severe perinatal (lethal) hypophosphatasia.
Hypophosphatasia is an inherited disorder characterized by defective bone mineralization and a deficiency in tissue-nonspecific alkaline phosphatase (TNSALP) activity. This disorder is caused by various mutations of the TNSALP gene. We report here the prenatal diagnosis of the perinatal (lethal) type of hypophosphatasia in a sibling of an affected infant. The infant had been found to have hypop...
متن کاملClinical and Genetic Findings of Turkish Hypophosphatasia Cases
OBJECTIVE Hypophosphatasia (HPP) is a rare, commonly unrecognized hereditary mineralization defect with a dramatically poor prognosis in severe cases. This study is the first to examine the detailed clinical and laboratory characteristics of patients with HPP and healthy carriers in Turkey.

متن کاملA Rare Case of Neonatal Hypophosphatasia: A Case Report
Hypophosphatasia is a rare hereditary disorder of bone metabolism.In this article, we presented the case of a male infant with a soft skull and short, deformed limbs at birth, followed by seizures and respiratory distress during admission in the neonatal intensive care unit (NICU). Prenatal ultrasound showed limb hypoplasia, skull hypomineralization, and polyhydramnios. Seizures occurred on day...
متن کاملHypophosphatasia in the Newborn.
Rathbun (1948) first described the syndrome of hypophosphatasia as a definite entity, although previous authors had described patients now thought to be examples of this syndrome. This disorder has also been called rickets with deficiency of alkaline phosphatase (Sobel, Clark, Fox and Robinow, 1953; Schlesinger, Luder and Bodian, 1955) and osteodysmetamorphosis foetalis (Engfeldt and Zetterstro...
