Who was studied 684,122 European ancestry individuals.
The effect
Each copy of the T allele shifted the measure 0.075 higher; p = 4 × 10−28.
Where it sits Chromosome 17, band 17q24.3 — inside ABCA5.

ClinVar record 3037281NM_172232.4(ABCA5):c.4415+3G>A
What this is ClinVar's aggregate record for this position (as of its 2026-10-12 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
C/CNo copy of the version the research linked to Hemoglobin levels. This is the starting point the study compared everyone against.
C/TOne copy of the version the research linked to Hemoglobin levels. That is a smaller link than two copies.
T/TTwo copies of the version the research linked to Hemoglobin levels. That is the strongest link of the three results. A link in a study is not a diagnosis.

Questions about rs77262773
What is rs77262773?
rs77262773 is a single position in the genome, in or near the ABCA5 gene. Published research associates it with hemoglobin levels. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.
What conditions is rs77262773 linked to?
On MyGeneLog this position is linked to Blood Cell Counts. The research behind each link, and its sources, are set out on that condition page.
Does having rs77262773 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 rs77262773 come from?
GWAS Catalog, Communications biology 2020, PMID:32327693. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
