rs2306283 SLCO1B1
Normal SLCO1B1 function at this position.
What is rs2306283?
rs2306283 is a single-nucleotide polymorphism (SNP) in the SLCO1B1 gene (Solute carrier organic anion transporter 1B1 (statin uptake)). Each person carries two copies, one from each parent, so a result is reported as a pair of letters such as AA. The table below describes what studies associate with each genotype; the association is statistical, across populations, and is not a diagnosis.
What does each rs2306283 genotype mean?
| Genotype | Association | What the evidence says | Confidence |
|---|---|---|---|
| AA | typical | Normal SLCO1B1 function at this position. | 80% |
| AG | typical | SLCO1B1 *1b carrier. Generally normal function; may modify *5 effect. | 80% |
| GG | typical | SLCO1B1 *1b homozygous. May have slightly increased transporter activity. | 80% |

Is rs2306283 on 23andMe and AncestryDNA chips?
Chip coverage is not recorded for this variant. Orviva reports it when a raw-data file contains it directly or via a well-correlated proxy SNP, and says so when it does not.

Genetic associations describe risk across populations, not a diagnosis for any one person. Most variants shift risk modestly and act alongside lifestyle, environment and other genes. Consumer DNA chips do not read every position and can be wrong at any single one. For general education only; talk to a clinician or genetic counsellor before acting on anything here, and never change a prescribed medicine without your prescriber.
