Aortic aneurysm (PheCode 442.1)

FBN1 · rs655015

Strength of the evidence

1 / 4

Its strongest genetic-study result is p = 10−12, with 2 associations in the GWAS Catalog.

How this is scored

4: ClinVar disease-causing, reviewed by an expert panel or a guideline (3–4 stars). 3: ClinVar, several labs agreeing (2 stars), or a genetic study at p ≤ 10−50. 2: ClinVar from one lab (1 star), or p ≤ 10−20. 1: ClinVar submitted without criteria (0 stars), or genome-wide significance (p ≤ 5×10−8). The higher of the two counts. It says how solid the evidence is, not whether it matters for a particular person.

What the study found

Who was studied 2,825 African American or Afro-Caribbean cases, 117,425 African American or Afro-Caribbean controls, 22,049 European ancestry cases, 419,651 European ancestry controls, 1,071 Hispanic or Latin American cases, 58,194 Hispanic or Latin American controls.

The effect Each copy of the T allele shifted the measure 0.113 lower (95% confidence interval 0.085-0.14); p = 2 × 10−12.

How common The T allele had a frequency of about 90% in the people studied.

Where it sits Chromosome 15, band 15q21.1 — in an intron of FBN1.

What each result means

C/C No copy of the version the research linked to Aortic aneurysm (PheCode 442.1). This is the starting point the study compared everyone against.
C/T One copy of the version the research linked to Aortic aneurysm (PheCode 442.1). That is a smaller link than two copies.
T/T Two copies of the version the research linked to Aortic aneurysm (PheCode 442.1). That is the strongest link of the three results. A link in a study is not a diagnosis.

Questions about rs655015

What is rs655015?

rs655015 is a single position in the genome, in or near the FBN1 gene. Published research associates it with aortic aneurysm (phecode 442.1). A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.

Does having rs655015 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 rs655015 come from?

GWAS Catalog, Science (New York, N.Y.) 2024, PMID:39024449. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
