Sensitive

Breast cancer

TESHL · rs13387042

Strength of the evidence

3 / 4

Its strongest genetic-study result is p = 10−57, with 8 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 10,052 European ancestry cases, 12,575 European ancestry controls; replicated in 45,290 European ancestry cases, 41,880 European ancestry controls.

The effect Each copy of the A allele carried 1.14 times the odds of Breast cancer (95% confidence interval 1.11-1.16); p = 2 × 10−57.

How common The A allele had a frequency of about 51% in the people studied.

Where it sits Chromosome 2, band 2q35 — in an intron of TESHL.

The share of all copies of this position that are each version. The ancestry rows are gnomAD's own groups (via Ensembl), as the survey defines them, not races.

What each result means

A/A Two copies of the version the research linked to Breast cancer. That is the strongest link of the three results. A link in a study is not a diagnosis.
A/G One copy of the version the research linked to Breast cancer. That is a smaller link than two copies.
G/G No copy of the version the research linked to Breast cancer. This is the starting point the study compared everyone against.
DNA databases also record a third, rare version at this position, carried on fewer than one in a hundred copies of the DNA. The three results above cover the two common versions only.
