Disease Profile

Congenitally corrected transposition of the great arteries

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.

no.svg

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

Congenitally corrected transposition of the great arteries is a rare heart defect that occurs when the ventricles and attached valves are switched. As a result, the aorta and the pulmonary artery are connected to the wrong lower heart chambers.[1][2] Click here to visit MayoClinic.com and view an image of this heart defect. While the oxygen-poor blood still flows to the lungs, and oxygen-rich blood still flows out to nourish the body, other heart problems (such as septal defects, pulmonary stenosis, tricuspid regurgitation, and heart block) are often associated with this defect and require treatment.[2]

Symptoms

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.

Cause

Currently the cause of congenitally corrected transposition of the great arteries is not known. Limited data suggests that air pollutants and hair dye may act as environmental risk factors for this rare defect. Also, having a family history of this heart defect is a risk factor. It has been estimated that the recurrence risk in siblings is around 3% to 5%.[3]

Treatment
