We treated a girl with Zellweger syndrome using a special infant formula supplemented with middle chain triglyceride (MCT) milk, docosahexaenoic acid (DHA), Lorenzo's oil, and Lunaria oil, which is rich in nervonic acid (C24:1). We examined the fatty acid contents of the plasma and red blood cell (RBC) membrane. Neurological development was evaluated using Denver developmental screening test an...

INTRODUCTION The placenta morphology from an XYY pregnancy abortus has not been reported in the medical literature. This case report consists of the first detailed documentation. The reported case is also highly unusual because the mother had two prior pregnancies with fetuses being confirmed to have Zellweger syndrome and one prior molar pregnancy. CASE PRESENTATION A 43-year-old Caucasian w...

BACKGROUND The peroxisome biogenesis disorders, which are caused by mutations in any of 13 different PEX genes, include the Zellweger spectrum disorders. Severe defects in one of these PEX genes result in the absence of functional peroxisomes which is seen in classical Zellweger syndrome. These patients present with hypotonia and seizures shortly after birth. Other typical symptoms are dysmorph...

3-Hydroxy-3-methylglutaryl coenzyme A lyase (HL, E.C. 4.1.3.4) has a unique dual localization in both mitochondria and peroxisomes. Mitochondrial HL ( approximately 31.0 kDa) catalyzes the last step of ketogenesis; the function of peroxisomal HL ( approximately 33.5 kDa) is unknown. On density gradient fractionation, normal human lymphoblasts contain both peroxisomal and mitochondrial HL wherea...

Profiles of saturated very-long-chain (> C22) fatty acids were studied in plasma, fibroblasts, erythrocytes, platelets, and leukocytes of patients affected by peroxisomal disorders such as Zellweger syndrome, X-linked adrenoleukodystrophy (X-ALD), and classic rhizomelic chondrodysplasia punctata (RCDP) and in controls. In Zellweger patients, the concentration of hexacosanoic acid (C26:0) and th...

The biosynthesis and intracellular localization of nonspecific lipid transfer protein (nsLTP) in control human subjects and in patients with peroxisome-deficient disorders were investigated. The molecular mass of human nsLTP was indistinguishable from that of rat nsLTP (13 kDa) by immunoblot analysis. Intracellular localization was identical with that of catalase, a marker enzyme of peroxisomal...

Previous work has established that the absence of peroxisomes, as occurs in Zellweger syndrome, is accompanied by the absence of cellular sterol carrier protein-2 (SCP2). In the present study, Zellweger-syndrome fibroblasts and peroxisome-deficient CHO-ZR78 cells were used to study the role of SCP2 in the intracellular transport of low density lipoprotein (LDL)-derived lysosomal cholesterol. By...

Zellweger syndrome (ZS) is a rare autosomal recessive inherited disorder within the spectrum of peroxisome biogenesis disorders. It is a progressive and fatal disorder with multiple congenital anomalies. There may be some challenges for anesthesiologists in patients with ZS. We report the anesthetic management of an infant with ZS undergoing closure of patent ductus arteriosus and pulmonary art...

During their classic studies on the Separation of lysosomes by centrifugation of rat liver homogenates, De Duve and bis group (1) observed that certain oxidative enzymes, such äs Z)-amino acid oxidase and uric acid oxidase wbich produce hydrogen peroxide, and catalase which attacks hydrogen peroxide, were always found in a discrete fraction which could be separated from lysosomes and mitochondr...
