Peroxisomes and cancer: The role of a metabolic specialist in a disease of aberrant metabolism. Biochim Biophys Acta Rev Cancer 2018; 1870:103-121. [PMID: 30012421 DOI: 10.1016/j.bbcan.2018.07.004] [Citation(s) in RCA: 45] [Impact Index Per Article: 7.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/12/2018] [Revised: 05/30/2018] [Accepted: 07/10/2018] [Indexed: 01/02/2023]
Abstract
Cancer is irrevocably linked to aberrant metabolic processes. While once considered a vestigial organelle, we now know that peroxisomes play a central role in the metabolism of reactive oxygen species, bile acids, ether phospholipids (e.g. plasmalogens), very-long chain, and branched-chain fatty acids. Immune system evasion is a hallmark of cancer, and peroxisomes have an emerging role in the regulation of cellular immune responses. Investigations of individual peroxisome proteins and metabolites support their pro-tumorigenic functions. However, a significant knowledge gap remains regarding how individual functions of proteins and metabolites of the peroxisome orchestrate its potential role as a pro-tumorigenic organelle. This review highlights new advances in our understanding of biogenesis, enzymatic functions, and autophagic degradation of peroxisomes (pexophagy), and provides evidence linking these activities to tumorigenesis. Finally, we propose avenues that may be exploited to target peroxisome-related processes as a mode of combatting cancer.

Distinct signatures of host-microbial meta-metabolome and gut microbiome in two C57BL/6 strains under high-fat diet. ISME JOURNAL 2014; 8:2380-96.

Abstract
A combinatory approach using metabolomics and gut microbiome analysis techniques was performed to unravel the nature and specificity of metabolic profiles related to gut ecology in obesity. This study focused on gut and liver metabolomics of two different mouse strains, the C57BL/6J (C57J) and the C57BL/6N (C57N) fed with high-fat diet (HFD) for 3 weeks, causing diet-induced obesity in C57N, but not in C57J mice. Furthermore, a 16S-ribosomal RNA comparative sequence analysis using 454 pyrosequencing detected significant differences between the microbiome of the two strains on phylum level for Firmicutes, Deferribacteres and Proteobacteria that propose an essential role of the microbiome in obesity susceptibility. Gut microbial and liver metabolomics were followed by a combinatory approach using Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR-MS) and ultra performance liquid chromatography time of tlight MS/MS with subsequent multivariate statistical analysis, revealing distinctive host and microbial metabolome patterns between the C57J and the C57N strain. Many taurine-conjugated bile acids (TBAs) were significantly elevated in the cecum and decreased in liver samples from the C57J phenotype likely displaying different energy utilization behavior by the bacterial community and the host. Furthermore, several metabolite groups could specifically be associated with the C57N phenotype involving fatty acids, eicosanoids and urobilinoids. The mass differences based metabolite network approach enabled to extend the range of known metabolites to important bile acids (BAs) and novel taurine conjugates specific for both strains. In summary, our study showed clear alterations of the metabolome in the gastrointestinal tract and liver within a HFD-induced obesity mouse model in relation to the host-microbial nutritional adaptation.

Abstract
Clinically, peroxisome biogenesis disorders (PBDs) are a group of lethal diseases with a continuum of severity of clinical symptoms ranging from the most severe form, Zellweger syndrome, to the milder forms, infantile Refsum disease and rhizomelic chondrodysplasia punctata. PBDs are characterised by a number of biochemical abnormalities including impaired degradation of peroxide, very long chain fatty acids, pipecolic acid, phytanic acid and xenobiotics and impaired synthesis of plasmalogens, bile acids, cholesterol and docosahexaenoic acid. Treatment of PBD patients as a group is problematic since a number of patients, especially those with Zellweger syndrome, have significant neocortical alterations in the brain at birth so that full recovery would be impossible even with postnatal therapy. To date, treatment of PBD patients has generally involved only supportive care and symptomatic therapy. However, the fact that some of the milder PBD patients live into the second decade has prompted research into possible treatments for these patients. A number of experimental therapies have been evaluated to determine whether or not correction of biochemical abnormalities through dietary supplementation and/or modification is of clinical benefit to PBD patients. Another approach has been pharmacological induction of peroxisomes in PBD patients to improve overall peroxisomal biochemical function. Well known rodent peroxisomal proliferators were found not to induce human peroxisomes. Recently, our laboratory demonstrated that sodium 4-phenylbutyrate induces peroxisome proliferation and improves biochemical function (very long chain fatty acid beta-oxidation rates and very long chain fatty acid and plasmalogens levels) in fibroblast cell lines from patients with milder PBD phenotypes. Dietary supplementation and/or modification and pharmacological induction of peroxisomes as treatment strategies for PBD patients will be the subject of this review.

Abstract
In the last few years many patients have been reported with a defect in peroxisomal fatty acid beta-oxidation of unknown origin. Using a combined approach based on direct activity measurements of straight-chain acyl-CoA oxidase and complementation analysis after somatic cell fusion of fibroblasts, we have now classified 13 patients into 4 distinct groups representing different gene defects. Remarkably, we found intragenic complementation in group 2 so that group 2 is in fact made up of 3 distinct subgroups. The underlying basis for this peculiar phenomenon probably has to do with the fact that bifunctional protein harbors two catalytic activities including enoyl-CoA hydratase and 3-hydroxyacyl-CoA dehydrogenase. In group 2A enoyl-CoA hydratase and 3-hydroxyacyl-CoA dehydrogenase are defective whereas in group 2B and 2C either the hydratase or 3-hydroxyacyl-CoA dehydrogenase component of the bifunctional protein is deficient.

Abstract
Peroxisomal disorders are divided into two groups from a clinical point of view. Diseases in the first group, peroxisome-deficient disorders (PDD), Zellweger-like syndrome, and isolated deficiencies of peroxisomal beta-oxidation enzymes, are characterized by common clinical features including psychomotor retardation, hypotonia, hepatic dysfunction and visual disturbance. The second group includes diseases with a unique manifestation, such as X-linked adrenoleukodystrophy, hyperoxaluria type I and rhizomelic chondrodysplasia punctata. We investigated clinical aspects and the genetic basis of PDD, and the significance of peroxisomes in the development of human brain. Neuroradiological and neurophysiological studies revealed that thick cortex, colpocephaly and multifocal spikes were characteristic findings of PDD patients in the early infantile period. Cytogenetic studies elucidated the presence of eleven complementation groups among PDD, indicating the presence of eleven pathogenic genes for PDD. Molecular studies elucidated two of these genes, PAF-1 and PXR-1. Immunohistochemical studies clarified that the catalase-positive neurons appeared in the basal ganglia, thalamus, and cerebellum at 28 weeks of gestation, and in the cortex at 35 weeks. Immunopositive glial cells appeared from the deep to superficial white matter with increasing gestational age. These results suggest the important role of peroxisomes in neuronal maturation and myelinogenesis.

Abstract
Pristanic acid oxidation measurements proved a reliable tool for assessing complementation in fused heterokaryons from patients with peroxisomal biogenesis defects. We, therefore, used this method to determine the complementation groups of patients with isolated defects in peroxisomal beta-oxidation. The rate of oxidation of pristanic acid was reduced in affected cell lines from all of the families with inherited defects in peroxisomal beta-oxidation, thus excluding the possibility of a defective acyl CoA oxidase. Complementation analyses indicated that all of the patients belonged to the same complementation group, which corresponded to cell lines with bifunctional protein defects. Phytanic acid oxidation was reduced in fibroblasts from some, but not all, of the patients. Plasma samples were still available from six of the patients. The ratio of pristanic acid to phytanic acid was elevated in all of these samples, as were the levels of saturated very long chain fatty acids (VLCFA). However, the levels of bile acid intermediates, polyenoic VLCFA, and docosahexaenoic acid were abnormal in only some of the samples. Pristanic acid oxidation measurements were helpful in a prenatal assessment for one of the families where previous experience had shown that cellular VLCFA levels were not consistently elevated in affected individuals.

Abstract
A new radiolabeled metabolite was released into the extracellular fluid by normal human skin fibroblasts that were labeled with [5,6,8,9,11,12,14,15-3H] arachidonic acid. This product continued to accumulate during a 24 h incubation, and its formation was not saturated at arachidonic acid concentrations up to 15 mumol/L. The compound, identified as hexadecatrienoic acid, was not produced by Zellweger fibroblasts which are deficient in peroxisomal fatty acid beta-oxidation. By contrast, radiolabeled hexadecatrienoic acid was produced by mutant fibroblasts having other peroxisomal defects, including X-linked adrenoleukodystrophy, adult Refsum's disease, and rhizomelic chondrodysplasia punctata. This radiolabeled metabolite also was produced by mutant fibroblasts that cannot oxidize long-chain fatty acids in the mitochondria. These results indicate that hexadecatrienoic acid is synthesized from arachidonic acid by peroxisomal beta-oxidation. The absence of this pathway may account for some of the biochemical and functional abnormalities that occur in Zellweger's syndrome.

Abstract
Until recently peroxisomal disorders were considered to be extremely rare and the diagnostic procedures available for postanatal and prenatal diagnosis were not widely known. At present, 17 human disorders are linked to peroxisomal dysfunction. The clinical, biochemical and morphological peroxisome heterogeneity described in the different diseases illustrate that only combined analysis of all the different approaches will lead to a correct diagnosis and a coherent pathophysiological model to guide ongoing research. With the study of human peroxisomal disease, advances have been gained as to the function of the peroxisome in normal and pathological conditions. Genetic analysis of peroxisome biogenesis and research on peroxisomal targeting signals are now in progress. Peroxisomal disorders are usually classified according to the degree of biochemical impairment. In this paper, a tentative classification of peroxisomal disorders will be proposed, based on the degree of biochemical abnormalities combined with new data obtained on whether or not defective peroxisome assembly is involved: (1) disorders with peroxisome assembly deficiencies; (2) disorders with single enzyme deficiencies. The clinical onset and the major symptoms of the various disorders, and the recently discovered findings are discussed.

Abstract
Phytanic acid alpha-oxidation was studied in cultures of skin fibroblasts and myoblasts from patients with various defects of the respiratory chain in order to obtain information on the subcellular site and the mechanism of this pathway. In fibroblasts from patients with complex IV (cytochrome c oxidase) deficiency or glutaricaciduria type II, phytanic acid alpha-oxidation was reduced to 14% of normal, whereas in myoblasts from patients with complex I (NADH-Q reductase) deficiency, it was normal. Apparently, at least one step of phytanic acid alpha-oxidation occurs in mitochondria and in this process electrons are transferred to the respiratory chain via the electron-transfer flavoprotein (ETF).

Abstract
Hepatic peroxisomes were studied by morphometric and immunocytochemical techniques in control patients and in four Zellweger syndrome patients, two infantile Refsum's (IRD) patients, one neonatal adrenoleukodystrophy (NALD) patient, and three patients with peroxisomal disorders (PD) which do not fit any currently recognised classification, but have disorders involving a defect in peroxisomal biogenesis. Peroxisomes which were ultrastructurally abnormal and greatly reduced in size and/or number were found in two of the Zellweger syndrome patients, and the NALD and IRD patients. There was variation in their numerical density ranging from none at all in two of the Zellweger syndrome patients to normal numbers in the IRD patients. In most patients there was a decrease in the immunolabelling of catalase over the peroxisomes. In the Zellweger syndrome and NALD patients, the small, abnormal peroxisomes did not label for any of the beta-oxidation proteins. The IRD patients and the PD patients however, were heterogeneous with respect to beta-oxidation labelling. The ultrastructural heterogeneity of peroxisomes in these peroxisomal disorders patients indicates there may be genotypic differences between the major groups and also within each group. The common factor in all the patients in this study where peroxisomes were present was the presence in the hepatic peroxisomes of an electron dense centre which did not label immunocytochemically for catalase or the beta-oxidation enzymes. This electron dense centre may indicate a structural abnormality in the peroxisomes in these patients.

Abstract
The oxidation of pristanic and phytanic acids by human skin fibroblasts was compared to that of their synthetic analogues, 2-methylpalmitic and 3-methylmargaric acids. The synthetic compounds and natural substrates were degraded at comparable rates in control and X-linked adrenoleukodystrophy fibroblasts. The alpha-decarboxylation of 3-methylmargaric acid, similarly to that of phytanic acid, was affected in Refsum disease and Zellweger syndrome, but not in X-linked adrenoleukodystrophy. The beta-oxidation of 2-methylpalmitic acid, similarly to that of pristanic acid, was deficient in fibroblasts derived from patients suffering from Zellweger syndrome, confirming the importance of peroxisomes in the breakdown of 2-methyl-branched fatty acids. No deficiency was observed in fibroblasts from X-linked adrenoleukodystrophy patients. The 1-14C-labelled 2- and 3-methyl-branched fatty acids, which are easier to synthesize that the natural analogues, are therefore valuable tools for the diagnosis of human peroxisomal disorders.

Abstract
A group of genetically determined peroxisomal diseases is characterized by both multiple enzymatic deficiencies and abnormal structural features of the organelle. The primary cause of the phenotypes is likely to involve peroxisome assembly impairment. Complementation analyses performed on fibroblasts of patients revealed the existence of at least eight groups that do not reflect the clinical classifications. Recently, the use of experimental models led to the identification of a gene encoding for a peroxisomal membrane protein (PAF-1) in which a mutation was associated with the altered phenotype in a complementation group of the Zellweger syndrome (paradigm of these diseases). Also revealed in Zellweger probands are mutations of a gene encoding another peroxisomal protein (PMP70).

Abstract
Induction of alpha-oxidation, a possible gluconeogenic process, which should produce odd-chain fatty acids from even-chain fatty acids, was studied in rats fasted or made diabetic with streptozotocin. When a omega-phenylated even-chain fatty acid, phenylbutyric acid (1.2 mmol/kg), was administered to rats under these conditions, a significant increase in the urinary excretion of benzoic acid, the metabolic end-product of omega-phenylated odd-chain fatty acids, was observed in fasted (3.54 +/- 0.46 mumol/day) and diabetic (6.73 +/- 2.10) rats (control, 0.58 +/- 0.43; P less than 0.001). Phenylated longer chain fatty acids, phenylhexanoic and phenyldecanoic acid, did not produce significantly more benzoic acid than did phenylbutyric acid. Although the rate of alpha-oxidation was very low compared to that of beta-oxidation, these results suggested that alpha-oxidation of fatty acids was induced under fasting or diabetic conditions, and that alpha-oxidation might take place at the butyric acid stage.

Abstract
Empty membrane ghosts of peroxisomes were found in fibroblasts from a patient with Zellweger's syndrome, a genetic disease of humans (Santos et al: Science 239:1536-1538, 1988). Import of soluble matrix proteins into the organelle was defective. We have now studied fibroblasts from seven patients representing five complementation groups of the syndrome (defined by complementation for peroxisome enzyme function). We find that empty peroxisome ghosts are present in all seven cell samples. Three patients, representing three complementation groups, give the same membrane pattern by immunofluorescence: few large ghosts. Three other patients, representing two complementation groups, give a second pattern: many large ghosts. The seventh patient's pattern is distinct. Thus, all seven of these patients exhibit Peroxisome IMport (PIM) mutations. Since membrane assembly occurs in these cells, the results indicate that biogenesis of organelle content and membrane proteins proceed by different mechanisms. Growth and division of the empty peroxisomal membrane must occur, but are modified by the mutations (ghost size and abundance vary). Cell fusion and immunofluorescence analyses of peroxisome size and catalase packaging formally demonstrate genetic complementation groups for peroxisome assembly in Zellweger syndrome.

Abstract
Genetic heterogeneity in peroxisome-deficient disorders, including Zellweger's cerebrohepatorenal syndrome, neonatal adrenoleukodystrophy and infantile Refsum disease, was investigated. Fibroblasts from 17 patients were fused using polyethylene glycol, cultivated on cover slips, and the formation of peroxisomes in the fused cells was visualized by immunofluorescence staining, using anti-human catalase IgG. Two distinct staining patterns were observed: (1) peroxisomes appeared in the majority of multinucleated cells, and (2) practically no peroxisomes were identified. Single step 12-(1'-pyrene) dodecanoic acid/ultraviolet (P12/UV)-selection confirmed that the former groups were resistant to this selection, most of the surviving cells contained abundant peroxisomes, and the latter cells died. In the complementary matching, [1-14C]lignoceric acid oxidation and the biosynthesis of peroxisomal proteins were also normalized. Five complementation groups were identified. Group A: Zellweger syndrome and infantile Refsum disease; Groups B, C and D: Zellweger syndrome; Group E: Zellweger syndrome, neonatal adrenoleukodystrophy and infantile Refsum disease. We compared these groupings with those of Roscher and identified eight complementation groups. There was no obvious relation between complementation groups and clinical phenotypes. These results indicate that the transport, intracellular processing and function of peroxisomal proteins were normalized in the complementary matching and that at least eight different genes are involved in the formation of normal peroxisomes and in the transport of peroxisomal enzymes.

Abstract
We have studied fibroblast cell lines derived from a control subject (cell line 85AD5035F) and three patients clinically described as having the Zellweger syndrome (cell line W78/515), the infantile form of Refsum disease (cell line BOV84AD) and hyperpipecolic acidaemia (cell line GM3605), respectively. The mutant cell lines belonged to the same complementation group. The fibroblasts were cultured under identical conditions and were harvested at different time intervals after reaching confluence. Several peroxisomal parameters were determined. In agreement with previous reports, a lowered enzymic activity of acyl-CoA: dihydroxyacetonephosphate acyltransferase and a decrease in latent catalase clearly distinguished the patient cell lines from the control cell line. However, the cell lines exhibited a phenotypic heterogeneity. This was most strikingly encountered when cells were processed for indirect immunofluorescence microscopy and stained with anti-(catalase). The control cells exhibited a punctate fluorescence, which is indicative of the presence of catalase in peroxisomes. In the mutant cell line W78/515 a diffuse fluorescence was observed, indicative of the presence of catalase in the cytosol. In the other two mutant cell lines a punctate fluorescence was observed in some of the cells. Moreover, clear differences in the extent of proteolytic processing of acyl-CoA oxidase were detected. The mutant cell line BOV84AD displayed a control-like pattern with all molecular forms of acyl-CoA oxidase (72, 52 and 20 kDa) present, whereas in the W78/515 cell line only the 72 kDa component could be visualised. The GM3605 cell line was intermediate in this respect.

Abstract
In the course of the last decade peroxisomal beta-oxidation has emerged as a metabolic process indispensable to normal physiology. Peroxisomes beta-oxidize fatty acids, dicarboxylic acids, prostaglandins and various fatty acid analogues. Other compounds possessing an alkyl-group of six to eight carbon atoms (many substituted fatty acids) are initially omega-oxidized in endoplasmic reticulum. The resulting carboxyalkyl-groups are subsequently chain-shortened by beta-oxidation in peroxisomes. Peroxisomal beta-oxidation is therefore, in contrast to mitochondrial beta-oxidation, characterized by a very broad substrate-specificity. Acyl-CoA oxidases initiate the cycle of beta-oxidation of acyl-CoA esters. The next steps involve the bi(tri)functional enzyme, which possesses active sites for enoyl-CoA hydratase-, beta-hydroxyacyl-CoA dehydrogenase- and for delta 2, delta 5 enoyl-CoA isomerase activity. The beta-oxidation sequence is completed by a beta-ketoacyl-CoA thiolase. The peroxisomes also contain a 2,4-dienoyl-CoA reductase, which is required for beta-oxidation of unsaturated fatty acids. The peroxisomal beta-hydroxyacyl-CoA epimerase activity is due to the combined action of two enoyl-CoA hydratases. (For a recent review of the enzymology of beta-oxidation enzymes see Ref. 225.) The broad specificity of peroxisomal beta-oxidation is in part due to the presence of at least two acyl-CoA oxidases, one of which, the trihydroxy-5 beta-cholestanoyl-CoA (THCA-CoA) oxidase, is responsible for the initial dehydrogenation of the omega-oxidized cholesterol side-chain, initially hydroxylated in mitochondria. Shortening of this side-chain results in formation of bile acids and of propionyl-CoA. In relation to its mitochondrial counterpart, peroxisomal beta-oxidation in rat liver is characterized by a high extent of induction following exposure of rats to a variety of amphipathic compounds possessing a carboxylic-, or sulphonic acid group. In rats some high fat diets cause induction of peroxisomal fatty acid beta-oxidation and of trihydroxy-5 beta-cholestanoyl-CoA oxidase. Induction involves increased rates of synthesis of the appropriate mRNA molecules. Increased half-lives of mRNA- and enzyme molecules may also be involved. Recent findings of the involvement of a member of the steroid hormone receptor superfamily during induction, suggest that induction of peroxisomal beta-oxidation represents another regulatory phenomenon controlled by nuclear receptor proteins. This will likely be an area of intense future research. Chain-shortening of fatty acids, rather than their complete beta-oxidation, is the prominent feature of peroxisomal beta-oxidation.(ABSTRACT TRUNCATED AT 400 WORDS)

Abstract
Diagnostic and pathogenetic investigations of peroxisomal disorders should include the study of the macroscopic and microscopic pathology of the liver, in addition to careful clinical observations, skeletal X-ray and brain CT scan, assays of very long-chain fatty acids and bile acid intermediates, and selected enzyme activities. This review of the literature also contains novel observations about the following syndromes: cerebro-hepato-renal (Zellweger) syndrome, X-linked and neonatal adrenoleukodystrophies (ALD, NALD), NALD-like syndromes, infantile phytanic acid storage, classical Refsum disease, rhizomelic and other forms of chondrodysplasia punctata (XD, XR, AR), hyperpipecolic acidaemia, primary hyperoxaluria I, pseudo-Zellweger and Zellweger-like syndromes, and single enzyme deficiencies. Microscopic data include catalase staining and morphometry of peroxisomes, immunolocalization of beta-oxidation enzymes, detection of trilamellar, polarizing inclusions in PAS-positive macrophages, fibrosis and iron storage. Peroxisomal enlargement appears to be related to functional deficit in beta-oxidation disorders as well as in rhizomelic chondrodysplasia punctata. Because normal peroxisomal localization of active beta-oxidation enzymes can accompany a C26 beta-oxidation deficit, other mechanisms such as impaired transport of metabolites should be investigated. 'Ghost'-like organelles are shown in the liver of an infantile Refsum patient and in an NALD-like case; immuno-gold labelling of membrane proteins did not reveal ghosts in Zellweger livers.

Abstract
A 5-year-old boy with panperoxisomal dysfunction is described. Clinical features included hypotonia, areflexia, and ataxia. Cognition, vision, hearing, and hepatic function were normal. A panel of peroxisomal markers, including very-long-chain fatty acids, phytanic acid, pipecolic acid, and catalase compartmentalization, were abnormal. This is a uniquely benign syndrome of disordered peroxisome biogenesis.

Abstract
Complementation studies, using fused cell lines from patients with peroxisomal disorders, have shown correction of defective plasmalogen synthesis and phytanic acid oxidation as well as an increase in the number of peroxisomes. At least six complementation groups have been reported. We demonstrate here that complementing cell lines also acquire the ability to oxidize very long chain fatty acids (VLCFA), and that complementation groups defined with this technique are identical to those reported previously when plasmalogen synthesis was used as the criterion for complementation. This VLCFA complementation technique is of particular value in the study of patients in whom defective VLCFA is the only or major enzymatic defect, and we show complementation between cell lines from two patients each with an isolated defect in one of the peroxisomal fatty acid beta-oxidation enzymes.

Abstract
The infantile and classic forms of phytanic acid storage disease belong to the newly recognized group of peroxisomal disorders. In this paper we report the full clinical, morphological and biochemical results in a patient with infantile phytanic acid storage disease. The results indicate a generalized loss of peroxisomal functions due to a deficiency of peroxisomes as demonstrated in hepatocytes and cultured skin fibroblasts.

Abstract
Peroxisomes play an essential role in human cellular metabolism. Peroxisomal disorders, a group of genetic diseases caused by peroxisomal dysfunction, can be classified into three groups: (1) disorders of peroxisome biogenesis with a generalized loss of peroxisomal functions (Zellweger syndrome, neonatal adrenoleukodystrophy, infantile Refsum disease, hyperpipecolic acidaemia); (2) disorders with a loss of multiple peroxisomal functions (rhizomelic chondrodysplasia punctata and Zellweger-like syndrome; (3) disorders with loss of a single peroxisomal function (X-linked adrenoleukodystrophy, peroxisomal thiolase deficiency, bifunctional protein deficiency, acyl-CoA oxidase deficiency, classic Refsum disease, hyperoxaluria type I and acatalasaemia). Prenatal diagnosis is indicated in all these genetic disorders with the exception of classic Refsum disease, most types of hyperoxaluria type I and acatalasaemia. A variety of techniques is available now for the prenatal diagnosis of peroxisomal disorders in the first or second trimester of gestation. Prenatal diagnosis was performed by us in 70 pregnancies at risk for a disorder of peroxisome biogenesis, three for rhizomelic chondrodysplasia punctata, four for X-linked adrenoleukodystrophy and two for a defect in peroxisomal beta-oxidation. Fourteen affected fetuses were identified; no false negative cases were obtained.
