Genes affected

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]

Collection Method: clinical testing

The c.155T>C (p.I52T) alteration is located in exon 2 (coding exon 2) of the SLCO1B7 gene. This alteration results from a T to C substitution at nucleotide position 155, causing the isoleucine (I) at amino acid position 52 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
