Congenitally corrected transposition of the great arteries
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.
Age of Onset
Autosomal dominant ?A pathogenic variant in only one gene copy in each cell is sufficient to cause an autosomal dominant disease
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
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
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.
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.

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. 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.
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.

Conditions with similar signs and symptoms from Orphanet
The differential diagnosis is centered on assessing whether the patient presents isolated malformations, or a spectrum of malformations, and includes double inlet left ventricle (see this term) with left-sided incomplete right ventricle, isomerism of atrial appendages with left-handed ventricular topology.
