Extractions: Pseudo-Zellweger syndrome Ashli O'Brien CLINICAL SIGNS OF PZS Pseudo-Zellweger syndrome is a rare hereditary disorder affecting infants, and usually results in death. Unusual problems in prenatal development, an enlarged liver, high levels of iron and copper in the blood, and vision disturbances are among the major manifestations of Pseudo-Zellweger syndrome. Pseudo-Zellweger syndrome is a rare, congenital (present at birth) disorder characterized by the reduction or absence of peroxisomes (cell structures that rid the body of toxic substances) in the cells of the liver, kidneys, and brain. Pseudo-Zellweger syndrome is one of a group of genetic disorders called the leukodystrophies that affect growth of the myelin sheath, the fatty covering, which acts as an insulator, on nerve fibers in the brain (1). The most common features of Pseudo-Zellweger syndrome include an enlarged liver, high levels of iron and copper in the blood, and vision disturbances. Some affected infants may show prenatal growth failure. Symptoms at birth may include lack of muscle tone and an inability to move. Other symptoms may include unusual facial characteristics, mental retardation, seizures, and an inability to suck and/or swallow. Jaundice and gastrointestinal bleeding may also occur (1). Pseudo-Zwllweger syndrome is an autosomal recessive contiguous gene syndrome (1).

Extractions: Algorithms for Evaluation william.wilcox@cshs.org Suspected IEM with Metabolic Acidosis, Diagnostic Flowchart The presence of metabolic acidosis is an important finding and the starting point for one of the two algorithms. If the anion gap is normal and associated with hyperchloremia, this suggests loss of bicarbonate either from the gastrointestinal tract or kidneys. The presence of renal tubular acidosis does not rule out an IEM, however. Galactosemia and Lowe's syndrome (oculocerebrorenal syndrome, an X-linked recessive disorder with congenital cataracts, proximal RTA, and mental retardation) as well as many other metabolic disorders which present later are associated with a RTA, usually a proximal RTA. RTA is often found with disorders of energy metabolism. Elevated anion gap acidosis can be divided into 3 categories depending on the presence of ketones and glucose level. Because the normal ketones (acetoacetic acid and 3-hydroxybutyrate) come from the oxidation of fatty acids, their absence associated with significant hypoglycemia can be suggestive of a fatty acid oxidation disorder. These disorders often present later in life with a Reye syndrome picture or "SIDS". The presence of ketones in the urine (may only be 1+) hypoglycemia suggests an organic aciduria or lactic acidosis. Hyperglycemia and ketonuria defines diabetes mellitus. Metabolic acidosis cannot be further differentiated without the results of the amino and organic acids. If these are normal (except for the changes found with lactic acidosis), then the lactate/pyruvate ratio and the glucose level will allow differentiation into 1) glycogen storage disease, gluconeogenesis disorders, or endocrine causes; 2) disorders of pyruvate metabolism; or 3) defects in mitochondrial energy metabolism.

Generalized Peroxisomal Defects spectrum is comprised of three disorders Zellweger syndrome (ZS; also has been referredto as cerebrohepatorenal syndrome), neonatal adrenoleukodystrophy (NALD http://www.peroxisome.org/Scientist/Biogenesis/generalizeddefectstext.html
Extractions: Peroxisome Biogenesis Disorders The Zellweger spectrum The Zellweger spectrum is comprised of three disorders: Zellweger syndrome (ZS; also has been referred to as cerebrohepatorenal syndrome), neonatal adrenoleukodystrophy (NALD), and infantile Refsum disease (IRD). Collectively, these disorders, along with rhizomelic chondrodysplasia punctata (RCDP; see below) are called the peroxisome biogenesis disorders, or PBDs. These disorders are caused by defects in any of at least 14 genes whose products are required for the proper assembly of the peroxisome. The distinction between the disorders is based on severity, with ZS being the most severe and IRD the least severe. The Zellweger spectrum of diseases are inherited in an autosomal recessive fashion, and the incidence of these disorders is somewhere between 1/25,000 and 1/50,000 births. Clinical phenotypes of the Zellweger spectrum Biochemical Phenotypes of the Zellweger spectrum The biochemical phenotype of these disorders is reflective of the defect in peroxisome biogenesis. Very long chain fatty acid (VLCFA) levels are increased compared to normal, phytanic acid levels are increased, and plasmalogen levels are reduced. There are also high levels of the bile acid intermediates THCA and DHCA, as well as increased levels of the lysine metabolite pipecolic acid. Genetic basis of the Zellweger spectrum As previously stated, diseases of the Zellweger spectrum result from defects in peroxisome biogenesis. Patient cell lines have been divided into 12 complementation groups (CGs), demonstrating that there are at least 12 genes involved in human peroxisome biogenesis. The molecular basis of disease for 11 of these complementation groups has been elucidated (see table below). CG 11 is not part of the Zellweger spectrum, but rather has the distinct phenotype of RCDP (see below).
Extractions: needs and parents with special needs children. Neonatal ALD is autosomal recessive in its pattern of inheritance, so unlike the other form of ALD it affects both males and females. The disorder is now fairly easy to diagnose through biochemical tests, which demonstrate abnormally high levels in the tissues and body fluids of the very long chain fatty acids typical of ALD. Neonatal ALD is similar to the Zellweger cerebrohepatorenal syndrome , and may actually represent a milder variant of Zellweger. While there is no doubt that it is distinct from X-linked ALD, the exact classification of this neonatal form of ALD is still indeterminant. Individuals with Neonatal ALD suffer severe or profound mental retardation and impaired psychomotor development, together with possible impaired liver function and retarded growth. The clinical presentation and course of neonatal ALD is still not fully defined. It may take the form of an extremely severe illness with intractable seizures during the earliest part of life, or manifest as a milder form where the sufferer may survive to their mid-teens or possibly longer.

Extractions: The research in this laboratory centers on the mechanism and control of phospholipid biogenesis at the enzymic and genetic levels, and also on the role of phospholipids in signal transduction across biological membranes. E. coli and we have used them to study their catalytic mechanisms and to raise specific antibodies to help identify the native enzymes and also to study the transcriptional and translational controls of their biogenesis under different physiological conditions. Recent findings indicate that not only ether lipids but cellular non-ether glycerolipids, such as triglycerides in adipose tissue, are also synthesized via the acyl DHAP pathway. We are also involved in studying the generation and metabolism of lipid second messengers, such as diacylglycerol (DAG), in biological signal transduction. We have developed a method for quantitative molecular species analysis of DAG to differentiate among its various cellular roles. Using this method, we have shown that following receptor activation, both inositol and choline-containing lipids break down to form DAG. However, the DAG formed from inositol lipids is recycled back to the parent lipids, while the DAG from choline- containing lipids is not recycled. The physiological function and the mechanism of recycling of the large amount of DAG formed after chronic receptor activation are being studied in our laboratory.

Extractions: 2. The newborn is particularly susceptible because of immature hepatobiliary function, with decrease in bile acid pool size, rate of synthesis, intraluminal concentration, and ileal uptake. Consequently, intraluminal fat digestion is impaired, and cholestatic effects of various endogenous and exogenous substances are enhanced. B. Clinical syndromes (Box 19-3). Neonatal cholestasis occurs in 1:2500 births, with extrahepatic obstruction accounting for half of the cases. Neonatal hepatitis, biliary atresia and at-antitrypsin deficiency are the three most common causes, with an approximate incidence of 1:5000, 1:10,000, and 1:20,000, respectively.
