Genes affected

SLCO2B1 (HGNC:10962): (solute carrier organic anion transporter family member 2B1) This locus encodes a member of the organic anion-transporting polypeptide family of membrane proteins. The protein encoded by this locus may function in regulation of placental uptake of sulfated steroids. Alternatively spliced transcript variants have been described. [provided by RefSeq, Nov 2010]

ACMG classification

Verdict is Uncertain_significance. Variant got 4 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.851

The c.303G>C (p.L101F) alteration is located in exon 4 (coding exon 4) of the SLCO2B1 gene. This alteration results from a G to C substitution at nucleotide position 303, causing the leucine (L) at amino acid position 101 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
