Rotor syndrome synonyms

Rotor syndrome is a rare, benign, autosomal recessive disorder of bilirubin metabolism, often referred to in medical literature as Rotor-type hyperbilirubinemia. While it does not have many common alternative names, it is historically classified alongside Dubin-Johnson syndrome due to their shared clinical presentation of chronic conjugated hyperbilirubinemia.

What are the common synonyms and historical names for Rotor syndrome?

In clinical practice, Rotor syndrome is the universally accepted term. Historically, it was sometimes categorized under the broader umbrella of "familial chronic idiopathic jaundice." Because the condition was first described in 1948 by Arturo Belleza Rotor, it is occasionally referred to as Rotor's syndrome in older textbooks or international medical journals. Unlike many other rare conditions that have complex eponyms, Rotor syndrome remains remarkably consistent in its nomenclature across different medical traditions and global health systems.

Why does Rotor syndrome have specific classification codes?

Medical professionals use standardized codes to ensure accuracy in electronic health records and international reporting. Rotor syndrome is officially recognized in major medical databases under the following identifiers:

• OMIM (Online Mendelian Inheritance in Man): #237450


• Orphanet: ORPHA793


• ICD-10: E80.6 (Other disorders of bilirubin metabolism)

The reason for these specific classifications is to distinguish Rotor syndrome from other forms of hereditary jaundice, such as Gilbert syndrome or Dubin-Johnson syndrome. While these conditions all cause elevated bilirubin, the underlying genetic mechanism for Rotor syndrome involves mutations in the SLCO1B1 and SLCO1B3 genes, which differentiate it from the transporter defects found in other syndromes.

Is the name Rotor syndrome used universally?

Yes, Rotor syndrome is the preferred term used by hepatologists and geneticists worldwide. Because the condition is extremely rare—with fewer than 100 cases documented in medical literature—it has not developed a wide variety of colloquial or regional synonyms. When reviewing your medical records, you may occasionally see it listed as benign familial conjugated hyperbilirubinemia, which is a descriptive clinical term rather than a formal name. This description is helpful for insurance coding and medical clarity, but it is not a distinct disease entity separate from Rotor syndrome.

How does the naming of Rotor syndrome affect patient care?

Understanding the nomenclature of Rotor syndrome is vital for patients when navigating healthcare systems. Because it is a benign condition, accurate labeling helps prevent unnecessary diagnostic testing, such as invasive liver biopsies, which were historically used to differentiate it from other liver diseases. By using the official designation Rotor syndrome, patients can ensure that their care team is referencing the specific genetic profile characterized by the deficiency of organic anion-transporting polypeptides (OATP1B1 and OATP1B3).

Next steps

• Consult with a board-certified hepatologist or gastroenterologist to confirm your diagnosis through specific genetic testing.


• Maintain a copy of your medical records using the official Rotor syndrome terminology to ensure continuity of care across specialists.


• Connect with the DiseaseMaps.org community to share experiences and find resources for rare liver disorders.


• Request a referral to a clinical geneticist if you are planning a family, as Rotor syndrome follows an autosomal recessive inheritance pattern.
