Canavan Disease: 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)

... was first described in 1931 by Myrtelle Canavan.[3]. The discovery of the gene for Canavan disease, and subsequent events, generated considerable controversy. In 1987 the Greenbergs, a family with two children affected by Canavan disease, donated tissue samples to Dr Reuben Matalon, a researcher looking for the Canavan gene. He successfully identified the gene in 1993, and developed a test for it that would enable antenatal counselling of couples at risk of having a child with Canavan disease.[4] For a while the Canavan Foundation offered free genetic testing with the test. However, in 1997, Dr Matalons employer, the Miami Childrens Hospital, patented the gene and started claiming royalties on the genetic test, forcing the Canavan Foundation to withdraw their testing. A subsequent lawsuit brought by the Canavan Foundation against the Miami Childrens Hospital was resolved with a sealed out-of-court settlement.

Abstract The disorder now identified as aspartoacylase deficiency is equivalent to the condition variously called spongy degeneration of the brain, spongy degeneration of the central nervous system in infancy, or spongy degeneration of infancy, and many publications have used the eponymic designation, Canavan disease. The first definition of this condition as a distinct clinical entity is properly credited to van Bogaert and Bertrand in 1949.1, 2 In retrospect, the first clinical description is attributed to Globus and Strauss in 1928.3 In 1931, Canavan described an infant with prominent enlargement of the head and cerebral and cerebellar spongy degeneration under the designation "Schilders encephalitis periaxialis diffusa."4 Eiselsberg is credited with the recognition of the familial nature of the disorder in 1937,5 but, like Jervis,6, 7 she described the condition as Krabbe disease. The reports of von Bogaert and Bertrand 1, 2 were comprehensive and described the essential pathologic and ...

The month of May is designated as Tay-Sachs and Canavan Diseases Awareness Month. Newborns with Tay-Sachs disease appear healthy at birth, but then symptoms start to occur at 6 months. The infant will start to lose motor skills and mental functions. Soon after, they become blind, deaf, mentally retarded, paralyzed, non-responsive to their environment and will eventually die by the age of 5. Tay-Sachs disease is caused by a lack of an enzyme called Hexosaminidase A (Hex A), which is needed for the body to break down the fatty waste substances that are found in the brain cells. Without Hex A, this substance accumulates abnormally and causes gradual damage until the nervous system shuts down completely and can no longer sustain life.. Newborns with Canavan disease also appear healthy at birth. However, at the ages of 3 and 9 months, subtle changes will start to occur. These changes include visual inattentiveness, inability to grasp objects, roll over, or like Tay-Sachs disease, perform motor tasks. ...
Canavan Disease is an autosomal recessive devastating demyelinating disease caused by a deficiency in Aspartoacylase (ASPA) enzyme. There is no available treatment. ASPA deficiency leads to:- the accumulation of high levels of N-acetylaspartate (NAA), involved in myelin degeneration and epilepsy;- the deficient synthesis of acetate in oligodendrocytes, that could impair CNS myelination.Lithium administration induces a decrease in NAA in the brain of the tremor rats (animal model for CD) and in one patient (JANSON, 2005). On the other hand, administration of acetate could improve myelination in Canavan patients.For this reason, we propose to combine both treatments: Lithium Gluconate and Glyceryl Triacetate (GTA). Eighteen patients, aged 1 to 15 years, will receive oral GTA or Lithium during 4 months, then both treatment in association during 6 months. Patients will be sequentially evaluated up to the end of the treatment and 2 months thereafter for:-tolerance of the therapy (careful monitoring ...

I wanted to understand what happens in a young body to cause these profound symptoms. I watched videos, read memoirs, devoured medical journal websites. Heres what I learned: a gene mutation prevents the production of a critical enzyme in the brain called apartoacyclase. Without this enzyme, an acid called NAA or N-acetylaspartate, is not broken down, thereby it accumulates to dangerous levels in the brain. This causes cells responsible for making myelin sheaths, known as oligodendrocytes, to fail at this critical developmental task. Myelin sheaths are the fatty covering, or the insulation, around nerve fibers in the brain. Without functioning myelin sheaths, communication between the nerve impulses and the body are misdirected, slowed down, or incomplete, and the brain deteriorates ...

Respite care enables the caregivers to maintain the ability to continue care giving. The benefits to carers described in the literature also fall into these two broad categories: stress reduction and self-esteem increase; and improved family functioning (Merriman and Canavan, 2007).. A second purpose of respite is to make it possible for people affected by a with rare condition to live according to their usual daily routine and to provide a place to experience and perform recreational and meaningful activities away from their parents/other caregivers. Benefits to service users mentioned in the literature are socialisation, and enjoyment of experiences outside the home (Merriman and Canavan, 2007).. Without respite, not only can families suffer economically and emotionally, caregivers themselves may face serious health and social risks as a result of stress and exhaustion associated with continuous care giving. Three fifths of family caregivers aged 19-64 surveyed recently by the Commonwealth ...

No one disputes the value of a good marriage, of course. Andrew Oswald, an economist at the University of Warwick, in fact tried to calculate that value, based on tens of thousands of happiness surveys collected here and in the U.K., and found that its worth $100,000-or roughly doubling your salary, because working Americans earn, on average, $46,996 per year. But you know what else was worth $100,000? A large circle of friends. And it turns out that Aristotle was right when he wrote in The Nicomachean Ethics that friends are the glue that binds cities together. In study after study, urban dwellers have a more substantial social network. In his 1982 classic about Californians, To Dwell Among Friends: Personal Networks in Town and City, the Berkeley, California-based sociologist Claude Fischer found a 40 percent uptick in the size of friendship-based social networks moving from semi-rural areas into the urban core. Even the recent study that found we had fewer confidants found better news for ...

From Medscape Medical News , Conference News. Neil Canavan. March 30, 2012 (New York, New York) - Peginterferon alfa-2a, in combination with the protease inhibitor boceprevir and ribavirin (R), was shown to have efficacy equivalent or superior to that seen with historical use of the same regimen with peginterferon alfa-2a - the standard of care - for treating hepatitis C virus (HVC) infection, according to data reported here at the International Conference on Viral Hepatitis (ICVH) 2012.. These results provide a definitive rationale for the inclusion of the alfa-2a interferon variant in the treatment regimen, allowing for greater ease of administration by the patient infected with HCV.. This is the first trial in which peginterferon alfa-2a was used as a backbone instead of alfa-2b, said study investigator John Howe, PhD, senior principal scientist, Merck & Co., Inc, Whitehouse, New Jersey.. In a previous study of the combination with alfa-2b, the RESPOND-2 (Retreatment with HCV Serine ...

From then on, every time Lazowski or Matulewicz treated non-Jewish patients, the doctors injected them with the dead typhus virus without telling them what they were doing or why. (Since Jews risked being shot if they tested positive for typhus, they were not injected with the virus.) To avoid attracting suspicion, rather than take blood samples from all the patients they injected, the doctors referred some patients to other physicians in the area to have their blood drawn there. That way, every doctor in the area submitted samples that tested positive for typhus, not just Lazowski and Matulewicz. The two men then paced their injections, referrals, and blood sample submissions to mimic the spread of a real typhus epidemic ...

Many of these diseases are inherited in an autosomal recessive manner, meaning that carriers are not affected; a child does not develop the disease unless he or she inherits the risk allele from both parents. Because some risk alleles appear at a high frequency among Ashkenazi Jews, the American College of Medical Genetics and the American College of Obstetricians and Gynecologists have recommended that individuals of AJ descent undergo carrier screening (and genetic counseling as necessary) for Tay Sachs disease, Canavan disease, familial dysautonomia, mucolipidosis IV, Niemann-Pick disease type A, Fanconi anemia type C, Bloom syndrome, and Gaucher disease. About a third of the Ashkenazi Jews in the New York City area carry at least one of the 16 primarily Jewish genetic diseases for which testing was available in 2010 [1]. Carrier frequencies for conditions appearing at relatively high frequency in Ashkenazi Jews are shown below, compiled from different sources including [2],[3] and [4]: ...
Spongy Degeneration with Cerebellar Ataxia, (SDCA2) is an inherited disease affecting the Belgian Shepherd breed. It is a severe neurodegenerative disease with monogenic autosomal recessive inheritance. The disease is characterised by rapidly progressing ataxia starting around the age of 5-8 weeks. Puppies are usually euthanised by the age of 8-12 weeks. The disease can also be caused by another mutation SDCA2 . We also offer a combined SDCA1 + SDCA2 test in this breed. .

Certain genetic diseases are more common in individuals of Ashkenazi Jewish heritage (Jewish individuals of Eastern European ancestry) compared to the non-Jewish population. The majority of these conditions are inherited in an autosomal recessive manner. This group of diseases includes Gaucher, Tay-Sachs, familial dysautonomia, Canavan, mucolipidosis IV, Niemann-Pick Type A and B, FANCC-related Fanconi anemia, and Bloom syndrome. While these conditions are observed outside of the Ashkenazi Jewish population, they occur at a lower frequency. It is estimated that an individual of Ashkenazi Jewish ancestry has a 20% to 25% chance of being a carrier of 1 of these diseases.. Gaucher Disease:. Gaucher disease is a relatively rare lysosomal storage disorder resulting from a deficiency of acid beta-glucocerebrosidase. Mutations in the beta-glucocerebrosidase gene, GBA, cause the clinical manifestations of Gaucher disease. There are 3 major types of Gaucher disease: nonneuropathic (type 1), acute ...
