Illumina Laboratory Services, Illumina RCV000402803 SCV000377314 uncertain significance Rotor syndrome 2017-09-13 criteria provided, single submitter clinical testing The SLCO1B3 c.853_856delAAAC (p.Lys285HisfsTer14) variant results in a frameshift and is predicted to result in premature termination of the protein. A literature search was performed for the gene, cDNA change, and amino acid change. No publications were found based on this search. The p.Lys285HisfsTer14 variant is reported at a frequency of 0.004243 in the Ashkenazi Jewish population of the Genome Aggregation Database. Based on the variant frequency, disease prevalence, disease penetrance, and inheritance mode, this variant could not be ruled out of causing disease. Due to the potential impact of frameshift variants and the lack of clarifying evidence, the p.Lys285HisfsTer14 variant is classified as a variant of unknown significance but suspicious for pathogenicity for Rotor syndrome. Note: bi-allelic variants in both the SLCO1B1 and SLCO1B3 genes combined have been shown to cause Rotor syndrome. For an individual to be affected with Rotor syndrome, they must carry a pathogenic variant in both copies of the SLCO1B1 gene and in both copies of the SLCO1B3 gene. This variant was observed by ICSL as part of a predisposition screen in an ostensibly healthy population.
