Where it sits Chromosome 15, band 15q25.2 — in an intron of HOMER2.

What ClinVar records

Classification Benign; criteria provided, single submitter (1 of 4 stars, 1 submitter), last evaluated 2019-08-13. ClinVar record 1296844 NM_004839.4(HOMER2):c.651+233T>C

What this is ClinVar's aggregate record for this position (as of its 2026-09-24 release), not a result about you. A classification describes the variant against the condition named, as laboratories submitted it. Whether a person carries this variant, and what that would mean for them, is a question for a clinical test and a genetic counsellor.

What each result means

A/A Published research associates this genotype (two copies of the reported risk allele) with a higher likelihood of Substance use disorder compared to the general population.
A/G Published research associates this genotype (one copy of the reported risk allele) with an intermediate association with Substance use disorder.
G/G Published research associates this genotype with typical/baseline likelihood of Substance use disorder — no copies of the reported risk allele.

Questions about rs2055891

What is rs2055891?

rs2055891 is a single position in the genome, in or near the HOMER2 gene. Published research associates it with substance use disorder. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.

What conditions is rs2055891 linked to?

On MyGeneLog this position is linked to Substance Use Disorder. The research behind each link, and its sources, are set out on that condition page.

Does having rs2055891 mean I will get this?

No. Common variants like this one move a probability slightly and, on their own, rarely decide anything about one person. Nothing on this page is a diagnosis, and health decisions should be made with a clinician who can see your whole picture.

Where does the information about rs2055891 come from?

GWAS Catalog, Molecular psychiatry 2026, PMID:41057643. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
