Rotor syndrome

Summary Summary


Listen
Rotor syndrome is an inherited disorder characterized by elevated levels of bilirubin in the blood (hyperbilirubinemia). Bilirubin is produced when red blood cells are broken down, and has an orange-yellow tint. The buildup of bilirubin in the body causes yellowing of the skin or whites of the eyes (jaundice), which is the only symptom of the disorder. Jaundice is usually evident in infancy or early childhood, and it may come and go. Rotor syndrome is caused by having mutations in both the SLCO1B1 and SLCO1B3 genes and is inherited in an autosomal recessive manner. The disorder is generally considered benign, and no treatment is needed.[1][2]

Symptoms Symptoms


Listen
Jaundice, characterized by yellowing of the skin and/or whites of the eyes (conjunctival icterus), is usually the only symptom of Rotor syndrome. Jaundice usually begins shortly after birth or in childhood and may come and go.[1]

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 Cause


Listen
Rotor syndrome is an inherited disorder caused by having mutations in both the SLCO1B1 and SLCO1B3 genes. These genes provide instructions for making proteins that are found in liver cells, where they transport bilirubin and other substances from the blood into the liver so that they can be cleared from the body. In the liver, bilirubin is dissolved in a digestive fluid called bile, and then excreted from the body.[2]

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 jaundice.[2]

Last updated: 4/9/2015

Diagnosis Diagnosis


Listen
Rotor syndrome is diagnosed based on symptoms and various laboratory tests. Physical exams in affected people are typically normal, except for mild jaundice.

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 Treatment


Listen
Rotor syndrome is considered a benign disorder and does not require treatment.[1]

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 proteins that are absent in affected people.[1] People with Rotor syndrome should make sure all of their health care providers are aware of their diagnosis and should check with their health care providers regarding drugs that should be avoided.

Find a Specialist Find a Specialist

If you need medical advice, you can look for doctors or other healthcare professionals who have experience with this disease. You may find these specialists through advocacy organizations, clinical trials, or articles published in medical journals. You may also want to contact a university or tertiary medical center in your area, because these centers tend to see more complex cases and have the latest technology and treatments.

If you can’t find a specialist in your local area, try contacting national or international specialists. They may be able to refer you to someone they know through conferences or research efforts. Some specialists may be willing to consult with you or your local doctors over the phone or by email if you can't travel to them for care.

You can find more tips in our guide, How to Find a Disease Specialist. We also encourage you to explore the rest of this page to find resources that can help you find specialists.

Healthcare Resources

  • To find a medical professional who specializes in genetics, you can ask your doctor for a referral or you can search for one yourself. Online directories are provided by the American College of Medical Genetics and the National Society of Genetic Counselors. If you need additional help, contact a GARD Information Specialist. You can also learn more about genetic consultations from Genetics Home Reference.

Related Diseases Related Diseases


Listen

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.

Conditions with similar signs and symptoms from Orphanet
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.
Visit the Orphanet disease page for more information.

Organizations Organizations


Listen

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. Inclusion on this list is not an endorsement by GARD.
