title: Homozygous mutation Arg768Trp in the ABC-transporter encoding gene MRP2/cMOAT/ABCC2 causes Dubin-Johnson syndrome in a Caucasian patient.
abstract: Dubin-Johnson syndrome (DJS) is an autosomal recessive disorder characterized by conjugated hyperbilirubinemia and caused by mutations of the ATP-binding cassette (ABC) transporter encoding gene MRP2/cMOAT/ABCC2. Previous studies reported on mutations in DJS patients and polymorphisms in healthy human individuals. The genomic DNA sequence of a female Caucasian DJS patient was analyzed by DNA sequencing and revealed the identification of a homozygous missense mutation C2302T. This DJS-causing alteration results in an amino acid exchange Arg768Trp.
