Variant summary

Our verdict is Benign. The variant received -16 ACMG points: 0P and 16B. BP6_Very_Strong BA1

The NM_019844.4(SLCO1B3):​c.-28_-11delATATTCACTTGGTATCTG variant causes a 5 prime UTR change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.268 in 1,469,848 control chromosomes in the GnomAD database, including 54,843 homozygotes. It is difficult to determine the true allele frequency of this variant because it is of type DEL_BIG, and the frequency of such variant types in population databases may be underestimated and unreliable. Variant has been reported in ClinVar as Benign (★★).

Genes affected

SLCO1B3 (HGNC:10961): (solute carrier organic anion transporter family member 1B3) This gene encodes a liver-specific member of the organic anion transporter family. The encoded protein is a transmembrane receptor that mediates the sodium-independent uptake of endogenous and xenobiotic compounds and plays a critical role in bile acid and bilirubin transport. Mutations in this gene are a cause of Rotor type hyperbilirubinemia. Alternative splicing of this gene and the use of alternative promoters results in transcript variants encoding different isoforms that differ in their tissue specificity.

SLCO1B3-SLCO1B7 (HGNC:54403): (SLCO1B3-SLCO1B7 readthrough) This locus represents naturally occurring readthrough transcription between the neighboring SLCO1B3 (solute carrier organic anion transporter family member 1B3) and SLCO1B7 (solute carrier organic anion transporter family member 1B7 (putative)) genes on chromosome 12. The readthrough transcript encodes a protein that shares sequence identity with both the upstream and downstream genes. [provided by RefSeq, Jun 2019]

ACMG classification

Our verdict: Benign. The variant received -16 ACMG points.

• BP6: Variant 12-20815710-AATATTCACTTGGTATCTG-A is Benign according to our data. Variant chr12-20815710-AATATTCACTTGGTATCTG-A is described in ClinVar as [Benign]. Clinvar id is 993345.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BA1: GnomAd4 highest subpopulation (NFE) allele frequency at 95% confidence interval = 0.296 is higher than 0.05.
