Where this position leads

What the study found

Who was studied 1,028,980 European ancestry individuals; replicated in 40,204 African ancestry individuals, 21,843 African American individuals.

The effect Each copy of the C allele shifted the measure 0.186 higher (95% confidence interval 0.14-0.23); p = 3 × 10⁻¹⁴.

Where it sits Chromosome 5, band 5q31.3 — in a regulatory region of IK.

What ClinVar records

Classification Benign for Mitochondrial complex I deficiency, nuclear type 1; criteria provided, multiple submitters, no conflicts (2 of 4 stars, 2 submitters), last evaluated 2018-01-13. ClinVar record 351226 NM_002488.4(NDUFA2):c.-48A>G

What this is ClinVar's aggregate record for this position (as of its 2026-10-19 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/C Two copies of the version the research linked to Systolic blood pressure. That is the strongest link of the three results. A link in a study is not a diagnosis.

C/T One copy of the version the research linked to Systolic blood pressure. That is a smaller link than two copies.

T/T No copy of the version the research linked to Systolic blood pressure. This is the starting point the study compared everyone against.

Questions about rs778593

What is rs778593?

rs778593 is a single position in the genome, in or near the IK gene. Published research associates it with systolic blood pressure. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.

What conditions is rs778593 linked to?

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

Does having rs778593 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 rs778593 come from?

GWAS Catalog, Nature genetics 2024, PMID:38689001. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
