Home Contact Us What is Canavan Disease? Canavan disease is a fatal genetic neurological disorder that deteriorates the white matter in the brain. This white matter (or myelin) insulates nerve cells in the brain and spinal cord, much like the insulation around a wire, to ensure that nerve impulses are transmitted throughout the body. In children with Canavan disease, a defective gene prevents the production of an enzyme responsible for breaking down an acid called NAA. An over accumulation of NAA in the brain is thought to drastically hinder healthy white matter formation, making the afflicted children incapable of holding up their heads, sitting or even speaking. The life expectancy of the typical Canavan child is between three and ten years with gradual deterioration of sight, ability to swallow and other senses. The Canavan gene has been identified allowing at risk couples to test for this deadly disease. Both parents must be carriers in order to have a child with Canavan (25% risk or 1 in 4).

Home Contact Us A Reason to Fight It is hard to imagine anything more devastating than a new mother being told that her baby has a brain disease and will die after battling prolonged respiratory illness, blindness, severe disabilities, and seizures. Our son, Max Randell was only four months old when diagnosed with Canavan disease. We wasted no time rallying together to fight for his life. Rather than accept the prognosis and put our beautiful baby boy in an institution as recommended by the doctors, we were determined to help our son live the happiest, longest and healthiest life he possibly could. Our commitment to Max has taken us on a life-altering journey through clinical trials for experimental medicine, fundraising, lobbying in Washington D.C., intense media relations, advocating for Max, and mentoring several other families along the way. The fight to give Max and other children battling Canavan disease, access to the most ambitious research and treatments that can be found, has given way to breakthroughs in gene therapy, which can potentially help millions suffering from neurodegenerative diseases. A happy boy worth fighting for;

Home Canavan Disease Patent Case The Research The Patent and Licensing Ethical Issues ... Discussion Canavan Disease Patent Case The Canavan Case is a case study that examines the use of a patent covering the molecular diagnosis of disease. This case has come to symbolize some of the negative effects gene patents may have on the provision of clinical medical services. The case has also caused many to consider the need for benefit sharing as one way for recognizing the contribution of patient groups and families to research and discovery. This essay is abstracted from a longer paper appearing as a chapter entitled Discoveries: Are There Limits on What may be Patented? in Who Owns Life? (Magnus D, Caplan A, McGee G, eds. Amherst NY: Prometheus Books, 2002). The study of this case was supported in part by grants from the Greenwall Foundation, the Charles E. Culpeper Foundation, the NIH, DOE and VA Consortium on Informed Consent Research, and a grant from the Dodge Foundation. I am indebted to Judith Tsipis, Daniel Greenberg, and Orren Alperstein Gelblum for sharing their personal stories and experiences with Canavan disease and the described research project, for actively involving me in their unfolding saga with Miami Children's Hospital, for freely sharing background information on the case, and for reading and commenting on earlier drafts of this manuscript; knowledge about the Canavan disease gene, like this chapter, would not exist but for their contributions. I received an honorarium from the Canavan Foundation for participating in the aforesaid meeting with MCH, and I have agreed to provide

Home Canavan Disease Patent Case The Research The Patent and Licensing Ethical Issues ... Discussion The Research In 1981, Dan and Debbie Greenberg had a son, Jonathan. After Jonathan failed to thrive, he was diagnosed with Canavan Disease. Canavan is a recessive genetic disease that will strike on average 1 of 4 children of couples when both parents carry a gene mutation that causes the disease. It is a degenerative spongiform brain disease that irreversibly leads to loss of body control and death, usually before the teen years. [i] There is no cure. In 1983, the Greenbergs had another child, Amy, who, against the odds, also was stricken with the disease. In 1987, Dan Greenberg approached Dr. Reuben Matalon and convinced him to study Canavan Disease. Matalon ran a laboratory performing clinical testing and research of phenylketonuria (PKU) and other familial disorders at the University of Illinois in Chicago. With blood, urine, and other tissue samples provided by the Greenbergs and another family affected by the disease, and “seed money” provided by Greenberg’s Chicago chapter of the National Tay-Sachs and Allied Diseases Association (NTSAD), within a year Matalon identified the deficiency of an enzyme, aspartoacylase, as the cause of Canavan Disease. This was great news, because it offered the possibility of a prenatal screening test.

Prevention Canavan disease Definition: Canavan disease is an inherited disorder of aspartic acid metabolism. It is characterized by degeneration of the white matter of the brain Alternative Names: Spongy degeneration of the brain; Aspartoacylase deficiency Causes, incidence, and risk factors: Canavan disease is inherited as an autosomal recessive trait. It is more common among Ashkenazi Jews than in the general population. A deficient enzyme , aspartoacylase, results in the accumulation of N-acetylaspartic acid in the brain. This causes a degeneration of the white matter. Typically, symptoms begin in the first year of life with loss of developmental milestones and death before 18 months of age.

The Scientist 15[18]:20, Sep. 17, 2001 RESEARCH Gene Therapy Targets Canavan Disease Clinical trial is first to use recombinant viruses in the brain to prevent neurodegeneration E-mail article By Douglas Steinberg Days after learning that their project would survive, thanks to a newly awarded $1.8 million National Institutes of Health grant, researchers at Jefferson Medical College in Philadelphia made medical history on June 5. During a three-hour operation, neurosurgeon Andrew Freese cut six small holes into a girl's skull. Through hair-thin catheters, he then infused areas of her brain with 90 billion virus particles that are expected to infect neurons and express a normal human gene that she lacks. By all accounts, Lindsay Karlin , a 6-year-old afflicted with Canavan disease, thereby became the first person to have recombinant viruses injected into her brain to treat an illness other than cancer. The Canavan trial signals a new phase in a 10-year offensive that gene therapy researchers have waged against neurodegenerative disorders. Previously limited mostly to cell-culture and animal experiments, the scientists are now poised or starting to take their protocols and reagents to the clinic.

Position Statement on Carrier Testing for Canavan Disease Canavan Disease is a serious incurable genetic disorder which causes mental retardation and is often fatal in childhood. It is cased by a genetic abnormality which produces a deficiency of the enzyme aspartoacylase and is inherited in an autosomal recessive pattern. Like Tay-Sachs Disease, Canavan Disease occurs at a higher frequency in individuals with Ashkenazi Jewish ancestry, estimated to be 1/40. The screening test to identify individuals who are carriers is a DNA-based test that is performed by only a few specialized laboratories. If both reproductive partners have an Ashkenazi Jewish background, we recommend that carrier testing for Canavan Disease be offered before pregnancy. If only one partner is of Ashkenazi Jewish descent, she/he should be offered carrier testing and the couple should be counseled regarding the limitations and benefits of carrier testing and prenatal diagnosis for this situation. If a family member is affected, the proband's mutation(s) should be defined and the relatives should be offered screening for this mutation(s). This screening could be combined with screening for Tay-Sachs Disease as both disorders are more common in the same ethnic group.

Main Page See live article Alphabetical index Canavan disease Canavan disease is a rare, inherited, neurological disorder characterized by spongy degeneration of the brain (in which the white matter is replaced by microscopic fluid-filled spaces). It is caused by a deficiency of an enzyme called aspartoacylase. Canavan disease is one of a group of genetic disorders called the leukodystrophies that affect growth of the myelin sheath of the nerve fibers in the brain. The myelin sheath is the fatty covering surrounding nerve cells that acts as an insulator. Symptoms of Canavan disease, which appear in early infancy and progress rapidly, may include mental retardation, loss of previously acquired motor skills, feeding difficulties, abnormal muscle tone (i.e., floppiness or stiffness), poor head control, and megalocephaly (abnormally enlarged head). Paralysis, blindness, or hearing loss may also occur. Although Canavan disease may occur in any ethnic group, it affects persons of Eastern European Jewish ancestry more frequently. There is no cure for Canavan disease, nor is there a standard course of treatment. Treatment is symptomatic and supportive. The prognosis for Canavan disease is poor. Death usually occurs before age 10.

Canavan in 1931. This disease is characterized by the progressive loss of white matter, the regions of the brain through which nerve impulses are sent to other parts of the brain or to the spinal cord. Loss of white matter gives the brain a spongy, degenerative appearance. Affected infants appear normal after birth. Later they are found to be hypotonic (floppy), fail to achieve head control, and become developmentally delayed by five to eight months of life. Characteristic features include an enlarged head, mental retardation, seizures and feeding difficulties. The severity and life expectancy of children with Canavan disease vary. Some die in the first year of life, while others survive beyond their teens. As no proven treatment is currently available for the underlying cause of Canavan disease, supportive care is essential. For example, insertion of a gastrostomy tube through an incision in the stomach may help maintain good nutrition and minimize the risk of aspiration (inhalation of food or liquids into the lungs). Medications to control seizures or other manifestations of Canavan disease are also important to consider.

Ashkenazi Disorders: Mendelian Canavan Disease Canavan disease is caused by a deficiency of an enzyme called aspartoacylase (ASA). Most children with this disorder appear normal at birth, but lack of this enzyme affects the brain and results in progressive deterioration of the affected child. The disease is life shortening with death typically occurring in the first or second decade of life. No effective treatment is available for this condition at this time. Read a true story about a child with Canavan Disease: Chicago Family Leads Fight Against Canavan Disease By Lisa Lewis, JUF News Disease frequency: 1 in 5,000 in the Jewish population Carrier frequency: 1 in 38 in the Jewish population. Diagnosis: Made by detecting lack of enzyme aspartoacylase in skin cells or by genetic testing of the gene for Canavan disease in blood. Inheritance: Autosomal Recessive Carrier testing: Available through genetic testing of the Canavan gene. Testing can identify about 97% of Ashkenazi Jewish carriers. Prenatal diagnosis: Genetic testing of the Canavan disease gene. This testing is available to those with a previous affected child or to couples found to be at risk by carrier testing.

Ashkenazi Disorders: Mendelian Canavan Disease Gene: The gene responsible for Canavan disease is the aspartoacyclase (ASA) gene, which is located at 17pter-p13. Aspartoacyclase hydrolyzes N-acetylaspartic acid (NAA) into aspartic acid and acetate. Its absence in the central nervous system leads to the accumulation of NAA in the brain resulting in demyelination and other symptoms seen in Canavan disease. Mutations and testing: Three common mutations in the ASA gene have been identified: E285A, Y231X, and A305E. Testing for these three mutations leads to a detection rate of ~99% in Ashkenazi Jews for disease-causing alleles and ~50-55% in non-Ashkenazi Jews. Traits: Canavan disease is a severe neurodegenerative disease (progressive leukodystrophy) with clinical onset usually by 3 to 6 months. Common features are hypotonia, poor head control, hyperextension of legs and flexion of arms, gastrointestinal reflux, feeding difficulties, severe mental deficiency, developmental delay, and macrocephaly. Over time, an affected child will develop spasticity, seizures, optic atrophy, and blindness. Death usually occurs within the first decade of life. Treatment: There is no effective treatment for Canavan disease. Supportive care is aimed at providing the affected child with comfort.

She and her husband Mike, 38, learned on April 19 that their year of round-the-clock efforts to convince the FDA to release an experimental gene transplant from clinical hold (originally imposed due to concerns about an unrelated transplant that resulted in the death of the recipient, who suffered from liver disease) have finally come to fruition. Max suffers from Canavan Disease, a genetic disorder, in which the brain turns spongy, leading to progressive, profound disability and death. It can occur in any ethnic group, however it is most prevalent in people of Eastern-European (Ashkenazi) descent.
