Summaries for Canavan Disease

NINDS : 53 Canavan disease is a gene-linked neurological disorder in which the brain degenerates into spongy tissue riddled with microscopic fluid-filled spaces. Canavan disease has been classified as one of a group of genetic disorders known as the leukodystrophies. Recent research has indicated that the cells in the brain responsible for making myelin sheaths, known as oligodendrocytes, cannot properly complete this critical developmental task.  Myelin sheaths are the fatty covering that act as insulators around nerve fibers in the brain, as well as providing nutritional support for nerve cells.  In Canavan disease, many oligodendrocytes do not mature  and instead die, leaving nerve cell projections known as axons vulnerable and unable to properly function.  Canavan disease is caused by mutation in the gene for an enzyme called aspartoacylase, which acts to break down the concentrated brain chemical known as N-acetyl-aspartate. Symptoms of Canavan disease usually appear in the first 3 to 6 months of life and progress rapidly.  Symptoms include lack of motor development, feeding difficulties, abnormal muscle tone (weakness or stiffness), and an abnormally large, poorly controlled head. Paralysis, blindness, or hearing loss may also occur. Children are characteristically quiet and apathetic. Although Canavan disease may occur in any ethnic group, it is more frequent among Ashkenazi Jews from eastern Poland, Lithuania, and western Russia, and among Saudi Arabians. Canavan disease can be identified by a simple prenatal blood test that screens for the missing enzyme or for mutations in the gene that controls aspartoacylase. Both parents must be carriers of the defective gene in order to have an affected child. When both parents are found to carry the Canavan gene mutation, there is a one in four (25 percent) chance with each pregnancy that the child will be affected with Canavan disease.

MalaCards based summary : Canavan Disease, also known as aspartoacylase deficiency, is related to leukodystrophy and cerebral degeneration, and has symptoms including opisthotonus An important gene associated with Canavan Disease is ASPA (Aspartoacylase), and among its related pathways/superpathways are Alanine, aspartate and glutamate metabolism and Neuroscience. Affiliated tissues include brain, testes and eye, and related phenotypes are global developmental delay and muscular hypotonia

Genetics Home Reference : 25 Canavan disease is a rare inherited disorder that damages the ability of nerve cells (neurons) in the brain to send and receive messages. This disease is one of a group of genetic disorders called leukodystrophies. Leukodystrophies disrupt the growth or maintenance of the myelin sheath, which is the covering that protects nerves and promotes the efficient transmission of nerve impulses. Neonatal/infantile Canavan disease is the most common and most severe form of the condition. Affected infants appear normal for the first few months of life, but by age 3 to 5 months, problems with development become noticeable. These infants usually do not develop motor skills such as turning over, controlling head movement, and sitting without support. Other common features of this condition include weak muscle tone (hypotonia), an unusually large head size (macrocephaly), and irritability. Feeding and swallowing difficulties, seizures, and sleep disturbances may also develop. The mild/juvenile form of Canavan disease is less common. Affected individuals have mildly delayed development of speech and motor skills starting in childhood. These delays may be so mild and nonspecific that they are never recognized as being caused by Canavan disease. The life expectancy for people with Canavan disease varies. Most people with the neonatal/infantile form live only into childhood, although some survive into adolescence or beyond. People with the mild/juvenile form do not appear to have a shortened lifespan.

NIH Rare Diseases : 52 Canavan disease is a progressive, fatal, genetic disorder affecting the central nervous system , muscles, and eyes. Early symptoms in infancy may include increased head size, weakness, low muscle tone and loss of head control. Symptoms progress to seizures , blindness, inability to move voluntarily and difficulty eating solids or swallowing liquids. This condition is caused by changes in the ASPA gene and is inherited in an autosomal recessive pattern. Canavan disease is diagnosed based on symptoms, laboratory testing, and genetic testing . There is no specific treatment. Treatment is focused on managing symptoms.

KEGG : 36 Canavan disease (CD) is an autosomal recessive neurodegenerative disorder associated with mutations of the gene encoding aspartoacylase (ASPA). In humans, the CD syndrome is marked by early onset, hydrocephalus, macroencephaly, psychomotor retardation, and spongiform myelin sheath vacuolization with progressive leukodystrophy. The disease is caused by aspartoacylase deficiency resulting in accumulation of N-acetylaspartic acid (NAA) in the brain. The increased levels of NAA in CD lead to swelling or sponginess of the brain. Two mutations account for about 98% of the alleles of Ashkenazi Jewish patients, in which population the disease is highly prevalent(E285A and Y231X in ASPA protein). Mutations in the ASPA gene in non-Jewish patients are different and more diverse.

UniProtKB/Swiss-Prot : 73 Canavan disease: A rare neurodegenerative condition of infancy or childhood characterized by white matter vacuolization and demyelination that gives rise to a spongy appearance. The clinical features are onset in early infancy, atonia of neck muscles, hypotonia, hyperextension of legs and flexion of arms, blindness, severe mental defect, megalocephaly, and death by 18 months on the average.
