Disease Profile
Rotor syndrome
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.
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.
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.
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.

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
The mutations in the SLCO1B1 and SLCO1B3 genes that cause Rotor syndrome either prevent the production of the transporting proteins, or prevent them from functioning properly. When this occurs, bilirubin is not effectively removed from the body and builds up, leading to
Diagnosis
There are two forms of bilirubin in the body: a toxic form called unconjugated bilirubin and a nontoxic form called conjugated bilirubin. People with Rotor syndrome have a buildup of both in their blood (hyperbilirubinemia), but having elevated levels of conjugated bilirubin is the hallmark of the disorder. Conjugated bilirubin in affected people is usually more than 50% of total bilirubin.[2][1]
To confirm a disgnosis of Rotor syndrome, a person may have the following performed:
- testing for serum bilirubin concentration
- testing for bilirubin in the urine
- testing for hemolysis and liver
enzyme activity (to rule out other conditions) - cholescintigraphy (also called an HIDA scan)
- testing for total urinary porphyrins[1]
Treatment
While no adverse drug reactions have been reported in people with Rotor syndrome, a number of commonly used drugs and/or their metabolites may have serious consequences in affected people. This is because some drugs enter the liver via one of the two transporter
Related diseases
Related diseases are conditions that have similar signs and symptoms. A health care provider may consider these conditions in the table below when making a diagnosis. Please note that the table may not include all the possible conditions related to this disease.

The principle differential diagnosis is Dubin-Johnson syndrome (DJS; see this term). DJS and RT can be distinguished on the basis of measurements of urinary coproporphyrin excretion (total coproporphyrin excretion levels are normal in DJS) and liver histology (black-brown liver cell pigmentation is specific to DJS). If liver biopsy is not feasible or is refused, 99mTc-HIDA cholescintigraphy (revealing prominent kidney excretion in RT) or molecular analysis (detection of ABCC2 gene mutations in DJS patients) can be useful for distinguishing between RT and DJS.

Organizations
Support and advocacy groups can help you connect with other patients and families, and they can provide valuable services. Many develop patient-centered information and are the driving force behind research for better treatments and possible cures. They can direct you to research, resources, and services. Many organizations also have experts who serve as medical advisors or provide lists of doctors/clinics. Visit the group’s website or contact them to learn about the services they offer.
