A rare neurodegenerative condition of infancy or childhood characterized by white matter vacuolization and demeylination that gives rise to a spongy appearance. Aspartoacylase deficiency leads to an accumulation of N-acetylaspartate in astrocytes. Inheritance may be autosomal recessive or the illness may occur sporadically. This illness occurs more frequently in individuals of Ashkenazic Jewish descent. The neonatal form features the onset of hypotonia and lethargy at birth, rapidly progressing to coma and death. The infantile form features developmental delay, DYSKINESIAS, hypotonia, spasticity, blindness, and megalencephaly. The juvenile form is characterized by ATAXIA; OPTIC ATROPHY; and DEMENTIA.

Mutation detection in the aspartoacylase gene in 17 patients with Canavan disease: four new mutations in the non-Jewish population. (1/34)

Canavan disease is a severe progressive autosomal recessive disorder, which is characterised by spongy degeneration of the brain. The disease is caused by mutations in the aspartoacylase gene. Two different mutations were reported on 98% of the alleles of Ashkenazi Jewish patients, in which population the disease is highly prevalent. In non-Jewish patients of European origin, one mutation (914C > A) is found in 50% of the alleles, the other alleles representing all kinds of different mutations. We here describe the results of the mutation analysis in 17 European, non-Jewish patients. Ten different mutations were found, of which four had not been described before (H21P, A57T, R168H, P181T). A deletion of exon4, which until now had only been described once, was revealed in all five alleles of Turkish origin tested, indicating that this is a founder effect in the Turkish population.  (+info)

Protecting subjects' interests in genetics research. (2/34)

Biomedical researchers often assume that sponsors, subjects, families, and disease-associated advocacy groups contribute to research solely because of altruism. This view fails to capture the diverse interests of many participants in the emerging research enterprise. In the past two decades, patient groups have become increasingly active in the promotion and facilitation of genetics research. Simultaneously, a significant shift of academic biomedical science toward commercialization has occurred, spurred by U.S. federal policy changes. The concurrent rise in both the roles that subjects play and the commercial interests they have presents numerous ethical challenges. We examine the interests of different research participants, finding that these interests are not addressed by current policies and practices. We conclude that all participants should be given a voice in decisions affecting ownership, access to, and use of commercialized products and services, and that researchers and institutions should negotiate issues relating to control of research results and the sharing of benefits before the research is performed.  (+info)

Effect of topiramate on enlargement of head in Canavan disease: a new option for treatment of megalencephaly. (3/34)

Canavan disease (CD) is a rare autosomal recessive genetic disorder characterized by early onset progressive spongy degeneration of the brain involving the axon's myelin sheath. Patients with CD have leukoencephalopathy and megalencephaly; clinically they show a variable course ranging from slow neurodegenerative course to no neurological development or rapid regression. Current treatment is symptomatic including management of seizures and spasticity. Topiramate (TPM) is a novel antiepileptic drug for treatment of a broad spectrum of seizure types in adults and children. We used TPM in two of our patients diagnosed with CD at six months of age. At seven months and 15 months' follow-up, respectively, each patient showed a decrease in head growth velocity. We suggest that TPM can be used in patients with CD and possibly in other childhood neurodegenerative diseases with leukoencephalopathy and megalencephaly. Further studies are required to reveal the underlying mechanisms that lead to decreased head growth velocity, and to conclude whether this ameliorates the clinical course of CD.  (+info)

Defective N-acetylaspartate catabolism reduces brain acetate levels and myelin lipid synthesis in Canavan's disease. (4/34)

Canavan's disease (CD) is a fatal, hereditary disorder of CNS development that has been linked to mutations in the gene for the enzyme aspartoacylase (ASPA) (EC 3.5.1.15). ASPA acts to hydrolyze N-acetylaspartate (NAA) into l-aspartate and acetate, but the connection between ASPA deficiency and the failure of proper CNS development is unclear. We hypothesize that one function of ASPA is to provide acetate for the increased lipid synthesis that occurs during postnatal CNS myelination. The gene encoding ASPA has been inactivated in the mouse model of CD, and here we show significant decreases in the synthesis of six classes of myelin-associated lipids, as well as reduced acetate levels, in the brains of these mice at the time of peak postnatal CNS myelination. Analysis of the lipid content of white matter from a human CD patient showed decreased cerebroside and sulfatide relative to normal white matter. These results demonstrate that myelin lipid synthesis is significantly compromised in CD and provide direct evidence that defective myelin synthesis, resulting from a deficiency of NAA-derived acetate, is involved in the pathogenesis of CD.  (+info)

Progress toward acetate supplementation therapy for Canavan disease: glyceryl triacetate administration increases acetate, but not N-acetylaspartate, levels in brain. (5/34)

Canavan disease (CD) is a fatal genetic neurodegenerative disorder caused by mutations in the gene for aspartoacylase, an enzyme that hydrolyzes N-acetylaspartate (NAA) into L-aspartate and acetate. Because aspartoacylase is localized in oligodendrocytes, and NAA-derived acetate is incorporated into myelin lipids, we hypothesize that an acetate deficiency in oligodendrocytes is responsible for the pathology in CD, and we propose acetate supplementation as a possible therapy. In our preclinical efforts toward this goal, we studied the effectiveness of orally administered glyceryl triacetate (GTA) and calcium acetate for increasing acetate levels in the murine brain. The concentrations of brain acetate and NAA were determined simultaneously after intragastric administration of GTA. We found that the acetate levels in brain were increased in a dose- and time-dependent manner, with a 17-fold increase observed at 1 to 2 h in 20- to 21-day-old mice at a dose of 5.8 g/kg GTA. NAA levels in the brain were not significantly increased under these conditions. Studies using mice at varying stages of development showed that the dose of GTA required to maintain similarly elevated acetate levels in the brain increased with age. Also, GTA was significantly more effective as an acetate source than calcium acetate. Chronic administration of GTA up to 25 days of age did not result in any overt pathology in the mice. Based on these results and the current Food and Drug Administration-approved use of GTA as a food additive, we propose that it is a potential candidate for use in acetate supplementation therapy for CD.  (+info)

Characterization of human aspartoacylase: the brain enzyme responsible for Canavan disease. (6/34)

Aspartoacylase catalyzes the deacetylation of N-acetylaspartic acid (NAA) to produce acetate and L-aspartate and is the only brain enzyme that has been shown to effectively metabolize NAA. Although the exact role of this enzymatic reaction has not yet been completely elucidated, the metabolism of NAA appears to be necessary in the formation of myelin lipids, and defects in this enzyme lead to Canavan disease, a fatal neurological disorder. The low catalytic activity and inherent instability observed with the Escherichia coli-expressed form of aspartoacylase suggested the need for a suitable eukaryotic expression system that would be capable of producing a fully functional, mature enzyme. Human aspartoacylase has now been successfully expressed in Pichia pastoris. While the expression yields are lower than in E. coli, the purified enzyme is significantly more stable. This enzyme form has the same substrate specificity but is 150-fold more active than the E. coli-expressed enzyme. The molecular weight of the purified enzyme, measured by mass spectrometry, is higher than predicted, suggesting the presence of some post-translational modifications. Deglycosylation of aspartoacylase or mutation at the glycosylation site causes decreased enzyme stability and diminished catalytic activity. A carbohydrate component has been removed and characterized by mass spectrometry. In addition to this carbohydrate moiety, the enzyme has also been shown to contain one zinc atom per subunit. Chelation studies to remove the zinc result in a reversible loss of catalytic activity, thus establishing aspartoacylase as a zinc metalloenzyme.  (+info)

Identification of the zinc binding ligands and the catalytic residue in human aspartoacylase, an enzyme involved in Canavan disease. (7/34)

Canavan disease is an autosomal-recessive neurodegenerative disorder caused by a lack of aspartoacylase, the enzyme that degrades N-acetylaspartate (NAA) into acetate and aspartate. With a view to studying the mechanisms underlying the action of human aspartoacylase (hASP), this enzyme was expressed in a heterologous Escherichia coli system and characterized. The recombinant protein was found to have a molecular weight of 36 kDa and kinetic constants K(m) and k(cat) of 0.20 +/- 0.03 mM and 14.22 +/- 0.48 s(-1), respectively. Sequence alignment showed that this enzyme belongs to the carboxypeptidase metalloprotein family having the conserved motif H(21)xxE(24)(91aa)H(116). We further investigated the active site of hASP by performing modelling studies and site-directed mutagenesis. His21, Glu24 and His116 were identified here for the first time as the residues involved in the zinc-binding process. In addition, mutations involving the Glu178Gln and Glu178Asp residues resulted in the loss of enzyme activity. The finding that wild-type and Glu178Asp have the same K(m) but different k(cat) values confirms the idea that the carboxylate group contributes importantly to the enzymatic activity of aspartoacylase.  (+info)

Structure of aspartoacylase, the brain enzyme impaired in Canavan disease. (8/34)

Aspartoacylase catalyzes hydrolysis of N-acetyl-l-aspartate to aspartate and acetate in the vertebrate brain. Deficiency in this activity leads to spongiform degeneration of the white matter of the brain and is the established cause of Canavan disease, a fatal progressive leukodystrophy affecting young children. We present crystal structures of recombinant human and rat aspartoacylase refined to 2.8- and 1.8-A resolution, respectively. The structures revealed that the N-terminal domain of aspartoacylase adopts a protein fold similar to that of zinc-dependent hydrolases related to carboxypeptidases A. The catalytic site of aspartoacylase shows close structural similarity to those of carboxypeptidases despite only 10-13% sequence identity between these proteins. About 100 C-terminal residues of aspartoacylase form a globular domain with a two-stranded beta-sheet linker that wraps around the N-terminal domain. The long channel leading to the active site is formed by the interface of the N- and C-terminal domains. The C-terminal domain is positioned in a way that prevents productive binding of polypeptides in the active site. The structures revealed that residues 158-164 may undergo a conformational change that results in opening and partial closing of the channel entrance. We hypothesize that the catalytic mechanism of aspartoacylase is closely analogous to that of carboxypeptidases. We identify residues involved in zinc coordination, and propose which residues may be involved in substrate binding and catalysis. The structures also provide a structural framework necessary for understanding the deleterious effects of many missense mutations of human aspartoacylase.  (+info)

Canavan disease is a rare, inherited genetic disorder that affects the white matter (the nerve cells that transmit nerve impulses) in the brain. It is caused by mutations in the gene for an enzyme called aspartoacylase, which is responsible for breaking down a compound called N-acetylaspartic acid (NAA) in the brain. As a result of this genetic defect, NAA accumulates to toxic levels in the brain, leading to progressive damage to the white matter and resulting in a number of neurological symptoms.

Canavan disease is typically diagnosed in infancy or early childhood, and it affects both boys and girls. The symptoms of Canavan disease can vary widely, but they often include developmental delays, hypotonia (low muscle tone), difficulty with movements and balance, seizures, and optic atrophy (degeneration of the optic nerve). As the disease progresses, individuals with Canavan disease may lose previously acquired skills, such as the ability to sit, stand, or walk.

There is currently no cure for Canavan disease, and treatment is focused on managing the symptoms and supporting the individual's overall health and well-being. Physical therapy, occupational therapy, and speech therapy can help improve motor function and communication skills, while medications may be used to control seizures and other symptoms. In some cases, individuals with Canavan disease may require assistive devices, such as wheelchairs or communication aids, to help them navigate their environment and communicate with others.

Beta-Hexosaminidase alpha chain is a subunit of the beta-hexosaminidase enzyme, which is responsible for breaking down complex carbohydrates in the body. This enzyme is composed of two subunits, an alpha and a beta unit, and there are different forms of the enzyme that contain varying combinations of these subunits (i.e., hexosaminidase A, hexosaminidase B, and hexosaminidase S).

Hexosaminidase A is the form responsible for breaking down GM2 gangliosides, a type of lipid molecule found in cell membranes. Deficiency or dysfunction of this enzyme can lead to accumulation of GM2 gangliosides in nerve cells, resulting in a group of genetic disorders known as the GM2 gangliosidoses. These disorders include Tay-Sachs disease and Sandhoff disease, both of which are characterized by progressive neurological deterioration and early death.

The alpha chain is encoded by the HEXA gene, which is located on chromosome 15. Mutations in this gene can lead to reduced or absent activity of hexosaminidase A, resulting in Tay-Sachs disease or other forms of GM2 gangliosidosis.

Amidohydrolases are a class of enzymes that catalyze the hydrolysis of amides and related compounds, resulting in the formation of an acid and an alcohol. This reaction is also known as amide hydrolysis or amide bond cleavage. Amidohydrolases play important roles in various biological processes, including the metabolism of xenobiotics (foreign substances) and endogenous compounds (those naturally produced within an organism).

The term "amidohydrolase" is a broad one that encompasses several specific types of enzymes, such as proteases, esterases, lipases, and nitrilases. These enzymes have different substrate specificities and catalytic mechanisms but share the common ability to hydrolyze amide bonds.

Proteases, for example, are a major group of amidohydrolases that specifically cleave peptide bonds in proteins. They are involved in various physiological processes, such as protein degradation, digestion, and regulation of biological pathways. Esterases and lipases hydrolyze ester bonds in various substrates, including lipids and other organic compounds. Nitrilases convert nitriles into carboxylic acids and ammonia by cleaving the nitrile bond (C≡N) through hydrolysis.

Amidohydrolases are found in various organisms, from bacteria to humans, and have diverse applications in industry, agriculture, and medicine. For instance, they can be used for the production of pharmaceuticals, biofuels, detergents, and other chemicals. Additionally, inhibitors of amidohydrolases can serve as therapeutic agents for treating various diseases, such as cancer, viral infections, and neurodegenerative disorders.

I'm sorry for any confusion, but "Jews" is not a medical term. It is a term used to describe a group of people who share cultural, religious, and ethnic heritage. The Jewish people originated from the ancient kingdoms of Israel and Judah. They are bound together by their religion, Judaism, which is based on the Torah, or the five books of Moses.

If you have any medical questions or terms that you would like defined, I'd be happy to help!

Aspartic acid is an α-amino acid with the chemical formula HO2CCH(NH2)CO2H. It is one of the twenty standard amino acids, and it is a polar, negatively charged, and hydrophilic amino acid. In proteins, aspartic acid usually occurs in its ionized form, aspartate, which has a single negative charge.

Aspartic acid plays important roles in various biological processes, including metabolism, neurotransmitter synthesis, and energy production. It is also a key component of many enzymes and proteins, where it often contributes to the formation of ionic bonds and helps stabilize protein structure.

In addition to its role as a building block of proteins, aspartic acid is also used in the synthesis of other important biological molecules, such as nucleotides, which are the building blocks of DNA and RNA. It is also a component of the dipeptide aspartame, an artificial sweetener that is widely used in food and beverages.

Like other amino acids, aspartic acid is essential for human health, but it cannot be synthesized by the body and must be obtained through the diet. Foods that are rich in aspartic acid include meat, poultry, fish, dairy products, eggs, legumes, and some fruits and vegetables.
