Gangliocytoma

Prevalence
Prevalence estimates on Rare Medical Network websites are calculated based on data available from numerous sources, including US and European government statistics, the NIH, Orphanet, and published epidemiologic studies. Rare disease population data is recognized to be highly variable, and based on a wide variety of source data and methodologies, so the prevalence data on this site should be assumed to be estimated and cannot be considered to be absolutely correct.

Inheritance

Autosomal dominant A pathogenic variant in only one gene copy in each cell is sufficient to cause an autosomal dominant disease.

no.svg

Autosomal recessive Pathogenic variants in both copies of each gene of the chromosome are needed to cause an autosomal recessive disease and observe the mutant phenotype.

no.svg

X-linked
dominant X-linked dominant inheritance, sometimes referred to as X-linked dominance, is a mode of genetic inheritance by which a dominant gene is carried on the X chromosome.

X-linked
recessive Pathogenic variants in both copies of a gene on the X chromosome cause an X-linked recessive disorder.

no.svg

Mitochondrial or multigenic Mitochondrial genetic disorders can be caused by changes (mutations) in either the mitochondrial DNA or nuclear DNA that lead to dysfunction of the mitochondria and inadequate production of energy.

no.svg

Multigenic or multifactor Inheritance involving many factors, of which at least one is genetic but none is of overwhelming importance, as in the causation of a disease by multiple genetic and environmental factors.

Summary

Gangliocytoma is a rare type of central nervous system (CNS) tumor made up of mature neurons. Gangliocytomas may occur in all age groups but most often occur in people between the ages of 10 and 30. The most common site is the temporal lobe of the brain, but they can arise anywhere in the CNS including the cerebellum, brainstem, floor of the third ventricle, and spinal cord. They are among the most frequent tumors associated with epilepsy. Signs and symptoms may depend on the tumor's location and may include seizures (most commonly); increased brain pressure; endocrine disorders; and focal symptoms. Gangliocytomas are generally slow-growing and usually do not become malignant. Treatment involves surgical removal of the tumor.[1][2]

Symptoms

Signs and symptoms caused by the presence of a gangliocytoma can vary depending on the tumor's location. Seizures are the most common symptom. Other symptoms may include increased brain pressure, endocrine disorders, and focal symptoms.[1][2] Gangliocytomas can also be asymptomatic (cause no symptoms) and may be diagnosed incidentally on imaging studies.[3]

This table lists symptoms that people with this disease may have. For most diseases, symptoms will vary from person to person. People with the same disease may not have all the symptoms listed. This information comes from a database called the Human Phenotype Ontology (HPO) . The HPO collects information on symptoms that have been described in medical resources. The HPO is updated regularly. Use the HPO ID to access more in-depth information about a symptom.
