Alteration of mannose transport in fibroblasts from type I carbohydrate deficient glycoprotein syndrome patients. (1/113)

The aim of the present study was to explore how mannose enters fibroblasts derived from a panel of children suffering from different subtypes of type I carbohydrate deficient glycoprotein syndrome: seven carbohydrate deficient glycoprotein syndrome subtype Ia (phosphomannomutase deficiency), two carbohydrate deficient glycoprotein syndrome subtype Ib (phosphomannose isomerase deficiency) and two carbohydrate deficient glycoprotein syndrome subtype Ix (not identified deficiency). We showed that a specific mannose transport system exists in all the cells tested but has different characteristics with respect to carbohydrate deficient glycoprotein syndrome subtypes. Subtype Ia fibroblasts presented a mannose uptake equivalent or higher (maximum 1.6-fold) than control cells with a D-[2-3H]-mannose incorporation in nascent N-glycoproteins decreased up to 7-fold. Compared to control cells, the mannose uptake was greatly stimulated in subtype Ib (4.0-fold), due to lower Kuptake and higher Vmax values. Subtype Ib cells showed an increased incorporation of D-[2-3H]-mannose into nascent N-glycoproteins. Subtype Ix fibroblasts presented an intermediary status with mannose uptake equivalent to the control but with an increased incorporation of D-[2-3H]-mannose in nascent N-glycoproteins. All together, our results demonstrate quantitative and/or qualitative modifications in mannose transport of all carbohydrate deficient glycoprotein syndrome fibroblasts in comparison to control cells, with a relative homogeneity within a considered subtype of carbohydrate deficient glycoprotein syndrome. These results are consistent with the possible use of mannose as a therapeutic agent in carbohydrate deficient glycoprotein syndrome Ib and Ix.  (+info)

A mutation in the human ortholog of the Saccharomyces cerevisiae ALG6 gene causes carbohydrate-deficient glycoprotein syndrome type-Ic. (2/113)

Carbohydrate-deficient glycoprotein syndrome (CDGS) represents a class of genetic diseases characterized by abnormal N-linked glycosylation. CDGS patients show a large number of glycoprotein abnormalities resulting in dysmorphy, encephalopathy, and other organ disorders. The majority of CDGSs described to date are related to an impaired biosynthesis of dolichyl pyrophosphate-linked Glc3Man9GlcNAc2 in the endoplasmic reticulum. Recently, we identified in four related patients a novel type of CDGS characterized by an accumulation of dolichyl pyrophosphate-linked Man9GlcNAc2. Elaborating on the analogy of this finding with the phenotype of alg5 and alg6 Saccharomyces cerevisiae strains, we have cloned and analyzed the human orthologs to the ALG5 dolichyl phosphate glucosyltransferase and ALG6 dolichyl pyrophosphate Man9GlcNAc2 alpha1,3-glucosyltransferase in four novel CDGS patients. Although ALG5 was not altered in the patients, a C-->T transition was detected in ALG6 cDNA of all four CDGS patients. The mutation cosegregated with the disease in a Mendelian recessive manner. Expression of the human ALG5 and ALG6 cDNA could partially complement the respective S. cerevisiae alg5 and alg6 deficiency. By contrast, the mutant ALG6 cDNA of CDGS patients failed to revert the hypoglycosylation observed in alg6 yeasts, thereby proving a functional relationship between the alanine to valine substitution introduced by the C-->T transition and the CDGS phenotype. The mutation in the ALG6 alpha1,3-glucosyltransferase gene defines an additional type of CDGS, which we propose to refer to as CDGS type-Ic.  (+info)

Effect of mutations found in carbohydrate-deficient glycoprotein syndrome type IA on the activity of phosphomannomutase 2. (3/113)

Seven mutant forms of human phosphomannomutase 2 were produced in Escherichia coli and purified. These mutants had a Vmax of 0.2-50% of the wild enzyme and were unstable. The least active protein (R141H) bears a very frequent mutation, which has never been found in the homozygous state whereas the second least active protein (D188G) corresponds to a mutation associated with a particularly severe phenotype. We conclude that total lack of phosphomannomutase 2 is incompatible with life. Another conclusion is that the elevated residual phosphomannomutase activity found in fibroblasts of some patients is contributed by their mutated phosphomannomutase 2.  (+info)

Microheterogeneity of serum glycoproteins in patients with chronic alcohol abuse compared with carbohydrate-deficient glycoprotein syndrome type I. (4/113)

BACKGROUND: Chronic alcohol abuse alters the normal N-glycosylation of transferrin, producing the carbohydrate-deficient transferrin isoforms. This alteration could be similar to that present in patients with carbohydrate-deficient glycoprotein syndrome type 1 (CDG1). We thus compared the alterations of N-glycans present in patients with alcoholism and patients with CDG1. METHODS: The N-glycans of serum glycoproteins were compared in sera of patients with alcoholism, patients with CDG1, and controls by two-dimensional electrophoresis, neuraminidase, peptide:N-glycosidase F, and endoglycosidase F2 treatments. A specific antibody directed against the amino acid sequence surrounding the N-432 N-glycosylation site of transferrin was prepared (SZ-350 antibody). RESULTS: In patients with alcoholism, the abnormal transferrin and alpha(1)-antitrypsin isoforms were devoid of a variable number of entire N-glycan moieties and were identical with those present in CDG1. In the serum of patients with alcoholism, this finding was less pronounced than in CDG1. In contrast to CDG1, there was no decrease in clusterin or serum amyloid P in patients with alcoholism. The SZ-350 antibody recognized only transferrin isoforms with one or no N-glycan moieties. CONCLUSION: Antibodies directed against specific N-glycosylation sites of glycoproteins could be useful for developing more specific immunochemical tests for the diagnosis of chronic alcohol abuse.  (+info)

A new type of carbohydrate-deficient glycoprotein syndrome due to a decreased import of GDP-fucose into the golgi. (5/113)

The fucosylation of glycoproteins was found to be deficient in a patient with a clinical phenotype resembling that of leukocyte adhesion deficiency type II (LAD II). While in LAD II hypofucosylation of glycoconjugates is secondary to an impaired synthesis of GDP-fucose due to a deficiency of the GDP-D-mannose-4, 6-dehydratase, synthesis of GDP-fucose was normal in our patient (Korner, C., Linnebank, M., Koch, H., Harms, E., von Figura, K., and Marquardt, T. (1999) J. Leukoc. Biol., in press). Import of GDP-fucose into Golgi-enriched vesicles was composed of a saturable, high affinity and a nonsaturable component. In our patient the saturable high affinity import of GDP-fucose was deficient, while import of UDP-galactose and the activity of GDPase, which generates the nucleoside phosphate required for antiport of GDP-fucose, were normal. Addition of L-fucose to the medium of fibroblasts restored the fucosylation of glycoproteins. We propose that this new form of carbohydrate-deficient glycoprotein syndrome is caused by impaired import of GDP-fucose into the Golgi.  (+info)

Determination of carbohydrate-deficient transferrin separated by lectin affinity chromatography for detecting chronic alcohol abuse. (6/113)

Carbohydrate-deficient transferrin (CDT) has been established as a valuable biological marker for detecting chronic alcohol abuse. To improve the diagnostic efficiency, we studied new CDT determination procedures involving the use of lectin affinity chromatography with Allomyrina dichotoma agglutinin (allo A) and Trichosanthes japonica agglutinin I (TJA-I) to isolate the CDT isoforms CDT-allo A and CDT-TJA, respectively. These procedures, based on detection of the CDT-allo A and CDT-TJA isoforms in sera, showed high sensitivity (100% and 98%, respectively) and high specificity (93% and 85%, respectively). These results demonstrate that the new procedures involving the use of lectin affinity chromatography are more useful for isolating markers in the CDT test than the conventional charge-based separation method.  (+info)

beta-Trace protein in human cerebrospinal fluid: a diagnostic marker for N-glycosylation defects in brain. (7/113)

As carbohydrate-deficient glycoprotein syndromes (CDGS) are multisystemic disorders with impaired central nervous function in nearly all cases, we tested isoforms of beta-trace protein (beta TP), a 'brain-type' glycosylated protein in cerebrospinal fluid (CSF) of nine patients with the characteristic CDGS type I pattern of serum transferrin. Whereas the serum transferrin pattern did not discriminate between the various subtypes of CDGS type I (CDGS type Ia, type Ic, and patients with unknown defect), beta TP isoforms of CDGS type Ia patients differed from that of the other CDGS type I patients. The percentage of abnormal beta TP isoforms correlated with the severity of the neurological symptoms. Furthermore, two patients are described, who illustrate that abnormal protein N-glycosylation can occur restricted to either the 'peripheral' serum or the central nervous system compartment. This is the first report presenting evidence for an N-glycosylation defect restricted to the brain. Testing beta TP isoforms is a useful tool to detect protein N-glycosylation disorders in the central nervous system.  (+info)

Glycosylation defects corrected by the changes in GDPmannose level. (8/113)

GDPMan is a key substrate in glycoprotein formation. This is especially true for lower eukaryotes where, in addition to the involvement in N-glycan biosynthesis and GPI-anchor formation, GDPMan takes part in the process which is unique for yeast and fungi i.e. O-mannosylation. Several lines of evidence have been presented that the level of GDPMan affects the process occurring in the Golgi compartment i.e. the elongation of outer mannose chain of glycoproteins in Saccharomyces cerevisiae. Results from our laboratory indicate that the availability of GDPMan affects also the early steps of glycoprotein formation ascribed to the endoplasmic reticulum, i.e. assembly of the dolichol-linked oligosaccharide as well as mannosyl-phosphodolichol (MPD) formation. The biochemical basis of carbohydrate deficient glycoprotein syndrome, a severe neurological disorder related to the GDPMan deficiency, is also discussed.  (+info)

A patient with carbohydrate-deficient glycoprotein syndrome type 1b (CDGS1b) is reported. The patient presented at 5 months of age with failure to thrive, prolonged diarrhoea, hepatomegaly and elevated serum liver transaminases. Liver biopsy showed steatosis. A low serum albumin and elevated serum liver transaminases persisted throughout childhood during which he had repeated infectious illnesses. From the age of 10 years he had oesophageal and duodenal ulceration together with recurrent bacterial cholangitis. Liver biopsy demonstrated hepatic fibrosis. CDGS1b was suspected, supported by the finding of a protein-losing enteropathy and finally confirmed by showing a reduced phosphomannoseisomerase activity. This case illustrates a rare condition with a wide range of presentations. [on SciFinder (R)] Kelly, D. F.; Boneh, A.; Pitsch, S.; Gold, H.; Fietz, M.; Nelson, P.; Oliver, M. R.
A congenital disorder of glycosylation (previously called carbohydrate-deficient glycoprotein syndrome) is one of several rare inborn errors of metabolism in which glycosylation of a variety of tissue proteins and/or lipids is deficient or defective. Congenital disorders of glycosylation are sometimes known as CDG syndromes. They often cause serious, sometimes fatal, malfunction of several different organ systems (especially the nervous system, muscles, and intestines) in affected infants. The most common subtype is CDG-Ia (also referred to as PMM2-CDG) where the genetic defect leads to the loss of phosphomannomutase 2, the enzyme responsible for the conversion of mannose-6-phosphate into mannose-1-phosphate. Historically, CDGs are classified as Types I and II (CDG-I and CDG-II), depending on the nature and location of the biochemical defect in the metabolic pathway relative to the action of oligosaccharyltransferase. The most commonly used screening method for CDG, analysis of transferrin ...

N2 - Congenital disorders of glycosylation (CDG) are a group of more than 130 inborn errors of metabolism affecting N-linked, O-linked protein and lipid-linked glycosylation. The phenotype in CDG patients includes frequent liver involvement, especially the disorders belonging to the N-linked protein glycosylation group. There are only a few treatable CDG. Mannose-Phosphate Isomerase (MPI)-CDG was the first treatable CDG by high dose mannose supplements. Recently, with the successful use of D-galactose in Phosphoglucomutase 1 (PGM1)-CDG, other CDG types have been trialed on galactose and with an increasing number of potential nutritional therapies. Current mini review focuses on therapies in glycosylation disorders affecting liver function and dietary intervention in general in N-linked glycosylation disorders. We ...

The primary hypothesis in this study is that adding simple milk sugar (galactose) to the diet of Congenital Disorders of Glycosylation patients will normalize the metabolic abnormalities. The secondary hypothesis posits that galactose intervention in Congenital Disorders of Glycosylation patients will normalize specific physiological biomarkers of protein glycosylation that can be utilized for future phase II/III trial development. The knowledge gained from the investigation of these two aims will help the investigators learn more about the disrupted metabolic mechanism of this disease and should lead to the identification of new disease biomarkers that can be used to evaluate clinical efficacy in future therapeutic trials.. Over a two-year period, the investigators will enroll patients diagnosed with Congenital Disorders of Glycosylation. The investigators propose to administer oral galactose supplementation for a period of 18 weeks in increasing dose to assess its effectiveness at normalizing ...

N2 - The serum iron transport protein human transferrin (hTf) is a glycoprotein (MW ∼79.6 kDa) containing two Asn-linked sites of glycosylation. The presence of specific glycoforms of hTf has been used as an indicator of carbohydrate-deficient glycoprotein syndrome (CDGS) or an indicator of alcohol abuse. The exact nature of the glycoforms described in the literature is controversial. In this work we demonstrate that the altered hTf glycoforms have lost one or both complete glycan side chains. Furthermore, we demonstrate using a combination of online immunoaffinity-postconcentration-mass spectrometry in conjunction with a blood spot cartridge that we can determine the relative quantities of the hTf glycoforms using ,5 μL blood in under 30 min. This is in contrast to previous methods that used 1 mL ...

Congenital disorder of glycosylation type 2A (CDG 2A) is a part of a group of rare inherited conditions that are present at birth (congenital) and involve defects in the glycosylation process. Glycosylation involves the joining of sugars and proteins (to form glycoproteins) by enzymes (proteins that function to convert specific substances in the body) in the cells of our bodies. These sugars (glycans) must be properly attached to specific proteins in the cells in order for the cells to function correctly. Due to the many functions of these glycoproteins throughout the body, if an error occurs in one of the many steps of the process, a wide variety of health problems may occur beginning in infancy. Symptoms can include psychomotor delays (movement, coordination, dexterity), mental retardation, and distinct physical features including thin lips, large gums, low-set rotated ears, and small head circumference. Some affected individuals may have gastrointestinal problems like diarrhea and reflux. ...
Congenital disorder of glycosylation type IIc or Leukocyte adhesion deficiency-2 (LAD2) is a type of leukocyte adhesion deficiency attributable to the absence of neutrophil sialyl-LewisX, a ligand of P- and E-selectin on vascular endothelium. It is associated with SLC35C1. This disorder was discovered in two unrelated Israeli boys 3 and 5 years of age, each the offspring of consanguineous parents. Both had severe mental retardation, short stature, a distinctive facial appearance, and the Bombay (hh) blood phenotype, and both were secretor- and Lewis-negative. They both had had recurrent severe bacterial infections similar to those seen in patients with LAD1, including pneumonia, peridontitis, otitis media, and localized cellulitis. Similar to that in patients with LAD1, their infections were accompanied by pronounced leukocytosis (30,000 to 150,000/mm3) but an absence of pus formation at sites of recurrent cellulitis. In vitro studies revealed a pronounced defect in neutrophil motility. Because ...

The spatial and temporal regulation of calcium signaling in neuronal growth cones is essential for axon guidance. In growth cones, the endoplasmic reticulum (ER) is a significant source of calcium signals. However, it is not clear whether the ER is remodeled during motile events to localize calcium signals in steering growth cones. The expression of the ER-calcium sensor, stromal interacting molecule 1 (STIM1) is necessary for growth cone steering toward the calcium-dependent guidance cue BDNF, with STIM1 functioning to sustain calcium signals through store-operated calcium entry. However, STIM1 is also required for growth cone steering away from semaphorin-3a, a guidance cue that does not activate ER-calcium release, suggesting multiple functions of STIM1 within growth cones (Mitchell et al. 2012). STIM1 also interacts with microtubule plus-end binding proteins EB1/EB3 (Grigoriev et al. 2008). Here, we show that STIM1 associates with EB1/EB3 in growth cones and that STIM1 expression is critical ...
Pf Morava: We could offer a cure for most of the symptoms of PMM2-CDG by enzyme replacement, or chaperone therapy or genetic manipulations. The real important question is though, what can we do for the central nervous system disease. Patient already have a brain malformation in most cases of PMM2-CDG at birth; can we treat that, or could we prevent that, to be able to treat the brain as well, and not only the body in CDG? Currently, we do not have a treatment option to reset organs, which had a developmental problem during fetal life. Theoretically, to do that, we would need to know the diagnosis very early and would need to treat the patients before they are born. This is still utopistic in 2016. ...
Most subtypes of CDG are classified as disorders of N-glycosylation, which involves carbohydrates called N-linked oligosaccharides. These oligosaccharides are created in a specific order to create specific sugar trees, which are then attached to proteins on various cells. Disorders of N-glycosylation are due to an enzyme deficiency or other malfunction somewhere along the N-glycosylation pathway.. As long as the defect is not identified, disorders of N-glycosylation are subdivided into defects of oligosaccharide assembly and transfer (CDG-Ix) and defects in oligosaccharide trimming and processing that occur after they are bound to proteins (CDG-IIx). As soon as the defect in an individual patient is clarified, a CDG name is given according to the current nomenclature.. Disorders of N-glycosylation include:. PMM2-CDG - This disorder is the most common type of CDG. More than 700 individuals have been identified. The disorder can be broken down into three stages: infantile multisystem, ...
Fiona Waddell represents CDG within ﻽VKS﻽, the Dutch Umbrella organization for metabolic diseases.

The age group from 11 to 36 months was the group with the highest prevalence of altered results, as 48% of individuals with altered results were in this age group.. The most common clinical manifestation in the investigated cases was NPMD, followed by seizures, hypotonia, intellectual impairment, and dysmorphisms. However, the most frequent symptoms in cases with alterations in the TfIEF were: NPMD, hypotonia, liver disease, intellectual impairment, and hepatomegaly, with inverted nipples (adjusted prevalence ratio=11), followed by liver disease, hypoglycemia, ophthalmic alterations, and familial recurrence representing the clinical manifestations statistically associated with altered TfIEF (Table 3).. Discussion. CDGs have been described as a major diagnostic challenge, since in this set of diseases almost all organs are affected, and a wide variety of symptoms have already been described. Therefore, the recommendation is to consider CDG in any case of unexplained disease, especially in the ...
There are over 40 known congenital disorders of glycosylation (CDGs), and a reformulation of their nomenclature has been proposed by Dr. Jaak Jaeken, who described the first CDG (Jaeken et al, 2009, Biochim Biophys Acta 1792:825-6). A new CDG has now been identified in several families (Cantagrel et al, 2010, Cell 142:203-17). Patients present notably with neurological disease, coagulation defects and skin findings (ichtiosis, dermatitis). By linkage and sequencing of candidate genes, mutations were found in SRD5A3 , encoding an enzyme which converts polyprenol to dolichol, a membrane anchor for oligosaccharides, thus shedding new light on the earliest steps of protein N-glycosylation.. Philippe Campeau, MD. ...
The major manifestations of this condition result from abnormalities in the brain, eye, and nervous system. Infants are noted to be floppy at birth and as they grow they fail to achieve normal milestones. Feeding problems are common and many children require some type of tube feeding to maintain nutrition. The amount of brain involvement is variable but most have some degree of cognitive impairment. The nature and severity of clinical problems vary widely. Motor development is impaired in most patients and muscle wasting is sometimes seen. Heart disease in the form of cardiomyopathy is common and many individuals, especially infants, develop liver disease. The sex organs, both primary and secondary may develop abnormally. Severe infections are always a threat. Older patients may develop abnormal curvature of the spine (kyphoscoliosis) and may eventually be confined to a wheelchair. Virtually all patients have reduced vision secondary to constant eye movements and inability to focus on targets. ...

It is estimated that when infant mortality is over 40/1000, less than 10% of the population have access to services for prevention and care of congenital disorders, but nearly 100% have access when infant mortality is 10/1000 or less (Blencowe et al. 2018a). The difference reflects the demographic transition and shifts the focus of medical policymaking from communicable to non-communicable diseases, including congenital and genetic disorders. This shift now affects the majority of the world population as 73% of births occur in countries with infant mortality of less than 45/1000. The average time taken for infant mortality to fall from 40 to 10 per 1000 births is 30-40 years (United Nations 2015)-close to the average working life of a health professional.. The question is then arising for an increasing number of countries: What services should be put in place for prevention and care of congenital disorders? The answer differs according to the disorder group. The burden of congenital ...

Heidelberg researchers model complex metabolic disturbance. A rare genetic defect that affects the so-called ALG2 gene can cause serious metabolic diseases in humans. It does so through the defective formation of proteins and sugar molecules. Until now, its rareness and complexity made it difficult to study this congenital glycosylation disorder. A research team led by Prof. Dr Joachim Wittbrodt and Dr Thomas Thumberger from the Centre for Organismal Studies (COS) of Heidelberg University has finally succeeded in introducing the underlying mutation in the ALG2 gene in a fish model, thus allowing the causes of these complex diseases to be studied at the molecular level.. Human cells are kept alive by the activity of millions of proteins. As they mature, these proteins must be modified in a myriad of ways, such as through the addition of sugar molecules - a crucial change for proper function. Defects in this sugar-adding process, also known as sugar decoration, are often lethal at the very early ...

Phosphomannomutase deficiency (PMM2-CDG) is the most frequent congenital disorder of glycosylation. The cerebellum is nearly always affected in PMM2-CDG patients, a cerebellar atrophy progression is observed, and cerebellar dysfunction is their main daily functional limitation. Different therapeutic agents are under development, and clinical evaluation of drug candidates will require a standardized score of cerebellar dysfunction. We aim to assess the validity of the International Cooperative Ataxia Rating Scale (ICARS) in children and adolescents with genetically confirmed PMM2-CDG deficiency. We compare ICARS results with the Nijmegen Pediatric CDG Rating Scale (NPCRS), neuroimaging, intelligence quotient (IQ) and molecular data. Our observational study included 13 PMM2-CDG patients and 21 control subjects. Ethical permissions and informed consents were obtained. Three independent child neurologists rated PMM2-CDG patients and control subjects using the ICARS. A single clinician administered the NPCRS

Deficiency of the enzyme phosphomannomutase 2 (PMM2) caused by loss-of-function mutations in the human PMM2 gene was shown over two decades ago to be the basis of a recessive congenital disorder of glycosylation originally called CDG1 or CDG1a. The first clinical observation by Jaeken and colleagues of a carbohydrate-deficient glycoprotein syndrome occurred four decades ago (Jaeken et al., 1980). The researcher and patient communities now refer to the disease as PMM2-CDG, which is the most common congenital disorder of glycosylation and affects at least 1000 patients worldwide (Chang et al., 2018). Classical pediatric clinical presentations include developmental delay, severe encephalopathy with axial hypotonia, abnormal eye movements, psychomotor retardation and cerebellar hypoplasia (Matthijs et al., 1997). As patients reach their teenage years and young adulthood, health challenges include hypogonadism, coagulation abnormalities and thrombotic events, retinitis pigmentosa and peripheral ...
Patients with Congenital Disorders of Glycosylation (CDG) have recessive mutations in genes required for protein N-glycosylation, resulting in multi-systemic disease. Despite the well-characterized biochemical consequences in these patients, the underlying cellular defects that contribute to CDG are not well-understood. Synthesis of the lipid-linked oligosaccharide (LLO), which serves as the sugar donor for the N-glycosylation of secretory proteins, requires conversion of fructose-6-phosphate to mannose-6-phosphate via the phosphomannose isomerase (MPI) enzyme. Patients deficient in MPI present with bleeding, diarrhea, edema, gastrointestinal bleeding, and liver fibrosis. MPI-CDG patients can be treated with oral mannose supplements, which is converted to mannose-6-phosphate through a minor complementary metabolic pathway, restoring protein glycosylation and ameliorating most symptoms, although liver disease continues to progress. Since Mpi deletion in mice causes early embryonic lethality and ...
Introduction: Congenital disorder of glycosylation type-1a is a multi-system disease involving neurological, gastrointestinal, ophthalmologic, cardiac or endocrine systems. In addition to hypothyroidism and hypergonadotropic hypogonadism, rare occurrences of hyperinsulinemic hypoglycemia in CDG patients have been reported. In the present report, we describe a patient diagnosed with CDG type-1a accompanied by hyperinsulinemic hypoglycemia, and whose responsive to diazoxide.. Case: The female patient was referred to our hospital at the age of 8 months with the complaint of failure to thrive. She was born at term as the first child of healthy non-consanguineous parents. Her weight was 6 kg (,3p), height was 63 cm (3p). She had strabismus, axial hypotonia, a hepatomegaly of 3 cm below the margin, inverted nipples and an abnormal distribution of subcutaneous fat. Routine investigations revealed hypoalbuminaemia, hypertransaminasemia, minimally raised prothrombin time. The patient s serum glucose was ...
We investigated the metabolic defect(s) of four children who presented with isolated cryptogenic chronic liver disease, coagulopathy, and abnormalities of several unrelated serum glycoproteins. Analysis of the patients serum glycoproteins and fibroblasts suggest they have a novel congenital disorder of glycosylation (CDG). All had abnormal transferrin (Tf) isoelectric focusing (IEF) profiles. More detailed analysis of Tf by electrospray ionization mass spectrometry (ESI-MS) showed a plethora of abnormal glycosylations that included loss of 1-2 sialic acids and 1-2 galactose units, typical of Group II defects. Tf from two patients also lacked 1-2 entire oligosaccharide chains, typical of Group One disorders. Total serum N-glycans were analyzed by HPLC and matrix-assisted laser desorption/ionization mass spectrometry and also showed increased proportion of neutral glycan chains lacking sialic acids and galactose units. Analysis of patient fibroblasts eliminated CDG-Ia, through CDG-Ih, -IL and ...

From UniProt:. Congenital disorder of glycosylation 1H (CDG1H): A form of congenital disorder of glycosylation, a multisystem disorder caused by a defect in glycoprotein biosynthesis and characterized by under-glycosylated serum glycoproteins. Congenital disorders of glycosylation result in a wide variety of clinical features, such as defects in the nervous system development, psychomotor retardation, dysmorphic features, hypotonia, coagulation disorders, and immunodeficiency. The broad spectrum of features reflects the critical role of N-glycoproteins during embryonic development, differentiation, and maintenance of cell functions. [MIM:608104]. ...
PEROXISOMES are single-membrane-bound organelles that house essential metabolic pathways in plants and other eukaryotes. For example, peroxisome biogenesis defects underlie the Zellweger spectrum of human congenital disorders, which often are fatal in infancy (reviewed in Wanders and Waterham 2005). Similarly, peroxisomes are essential for plant embryogenesis and development following germination (reviewed in Hu et al. 2012). The essential role of plant peroxisomes likely reflects the importance of peroxisomal enzymes, which catalyze key steps in photorespiration, fatty acid β-oxidation, jasmonate production, and conversion of the protoauxin indole-3-butyric acid (IBA) to the active auxin indole-3-acetic acid (IAA) (reviewed in Hu et al. 2012).. Peroxisomes import matrix proteins from the cytosol with the assistance of peroxin (PEX) proteins. Most matrix proteins are directed to the peroxisome by a C-terminal peroxisome-targeting signal 1 (PTS1) that binds the cytosolic receptor PEX5 (Keller et ...

Hudson Freeze, a recipient of the 2013 Golden Goose award for his discovery of a special bacterium and a world expert in glycosylation disorders, is said to go beyond just science.
The most abundant modification of proteins in eukaryotes is N-linked glycosylation:more than 10000 different acceptor sites are N-glycosylated in the mouse proteome. The process is essential because it underpins the folding and quality control of non-cytoplasmic (organelle-targeted), membrane-embedded, or secreted proteins. N-glycosylation is involved in organism development, the immune response, and host-pathogen interactions. Finally, a multitude of diseases are linked to the dysfunction of this process, including the various congenital disorders of glycosylation (CDGs).This proposal focuses on the central enzyme in the N-glycosylation pathway, oligosaccharyltransferase (OST). OST is a complex molecular machine that is embedded in the membrane of the Endoplasmic Reticulum (ER), where it catalyzes the transfer of a glycan moiety from a lipid-linked oligosaccharide (LLO) onto acceptor proteins that contain a recognition sequence N-X-S/T (the glycosylation sequon). After its covalent attachment ...

Introduction: Sudden cardiac death (SCD) in the young is rare and should always lead to suspicion of a genetic cardiac disorder. We describe a family, in which the proband was a girl deceased by sudden cardiac death in the playground at thirteen years of age. The index-patient had short stature, cleft palate but no previous cardiac symptoms. We found an uncommon cause of cardiomyopathy, due to a congenital disorder of glycosylation (CDG), previously described to cause a variable range of usually mild symptoms, and not previously found to cause SCD as the first symptom of the condition. Methods: The index patient underwent postmortem genetic testing/molecular autopsy for genes known to cause SCD, without a detection of causative agent, why two siblings of similar phenotype as the deceased sister underwent clinical-exome genetic sequencing (next generation sequencing). All first-degree relatives underwent clinical examination including cardiac ultrasound, Holzer-ECG, exercise stress test and ...

The regulation of the transcriptome is key to cellular processes that underpin cell biology, development and tissue function. All classes of cellular RNA are subject to post-transcriptional modification, be it by direct chemical modification, editing or non-templated nucleotide additions. It is now emerging that the modification status of the transcriptome is dynamic and responsive to environmental/developmental cues. Together, this has elicited the realisation of an epitranscriptome where post-transcriptional RNA modification coupled with recruitment of effector RNA binding proteins dynamically regulates genomic output. Importantly, mutations in setting or reading RNA modifications are causative of many human diseases or congenital disorders. This meeting aims to explore all aspects of this emerging topic, from methods development to molecular mechanism. Most importantly, the meeting will place an emphasis on the contribution of RNA modification to mammalian development, tissue homeostasis ...
As a graduate student, I studied the genetics of Hirschsprung disease, a congenital disorder of the nervous system in the gut (and, as I describe in my book, a disease that would affect my own family many years later). Among the things I found to be most gratifying (and yes, occasionally frustrating) in my doctoral studies were the interactions with Hirschsprung patients and families. We students had pledged our fealty to Science writ large, yes, but we werent studying roundworms or fruit flies. Our subjects (a descriptor of research participants that, in my opinion, is condescending and should be retired ASAP) were thinking feeling human beings. If we found a highly penetrant mutation in their DNA, it had the potential to alter their reproductive decisions and their lives. It meant something to them. ...
