Objective:
To explore the genetic basis for a patient featuring Rotor syndrome.
Methods:
Clinical data of the patient was collected. Whole exome sequencing (WES) based on high-throughput sequencing technology was carried out. Long-interspersed element-1 (LINE-1) insertion in intron 5 of the SLCO1B3 gene was detected by using tri-primer single tube PCR.
Results:
WES revealed that the patient has carried homozygous c.1738C>T nonsense variants of the SLCO1B1 gene. He was also found to harbor a homozygous insertion of LINE-1 in intron 5 of the SLCO1B3 gene, which has caused skipping of exon 5 or exons 5 to 7 and introduced a stop codon in the SLCO1B3 transcript.
Conclusion:
The homozygous c.1738C>T variant of the SLCO1B1 gene and homozygous insertion of LINE-1 in intron 5 of the SLCO1B3 gene probably underlay the Rotor syndrome in this patient.

Comparing Copy Number Variations and SNPs
Copy number variations or CNVs are the structural variations that cover more than 1kb of DNA sequence. The single nucleotide polymorphism (SNP), on the other hand, is a single nucleotide change or a point mutation that is found in more than 1%...
