Summary
Rotor syndrome, a rare liver condition, causes jaundice from birth. This case highlights a familial pattern of impaired bromosulphalein excretion, suggesting a genetic basis for this rare disorder.
Area of Science:
- Hepatology
- Clinical Genetics
- Biochemistry
Background:
- Rotor syndrome is a rare autosomal recessive disorder.
- It is characterized by conjugated hyperbilirubinemia due to defects in hepatic uptake and excretion of bilirubin.
Observation:
- A 17-year-old female presented with lifelong jaundice.
- Investigations revealed normal biliary channels, elevated urinary coproporphyrins, and retarded bromosulphalein excretion.
- Liver histology was normal.
Findings:
- The patient exhibited key biochemical markers of Rotor syndrome.
- A familial study indicated an autosomal recessive inheritance pattern, with the mother showing a similar defect in bromosulphalein excretion.
Implications:
- This case reinforces the importance of considering Rotor syndrome in the differential diagnosis of inherited conjugated hyperbilirubinemia.
- Understanding the genetic basis of Rotor syndrome is crucial for accurate diagnosis and genetic counseling.
- Further research into the specific genetic mutations and their functional consequences is warranted.
