rs11571833 BRCA2
A allele associated with decreased risk of Lung cancer (conditioned on cigarettes per day) (OR=0.64). [GWAS Catalog]
What is rs11571833?
rs11571833 is a single-nucleotide polymorphism (SNP) in the BRCA2 gene. Each person carries two copies, one from each parent, so a result is reported as a pair of letters such as AA. The table below describes what studies associate with each genotype; the association is statistical, across populations, and is not a diagnosis.
What does each rs11571833 genotype mean?
| Genotype | Association | What the evidence says | Confidence |
|---|---|---|---|
| AA | typical / lower | A allele associated with decreased risk of Lung cancer (conditioned on cigarettes per day) (OR=0.64). [GWAS Catalog] | 85% |
| TT | elevated | T allele associated with significantly increased risk of Lung cancer (OR=2.47). [GWAS Catalog] | 80% |
Is rs11571833 on 23andMe and AncestryDNA chips?
Chip coverage is not recorded for this variant. Orviva reports it when a raw-data file contains it directly or via a well-correlated proxy SNP, and says so when it does not.

Genetic associations describe risk across populations, not a diagnosis for any one person. Most variants shift risk modestly and act alongside lifestyle, environment and other genes. Consumer DNA chips do not read every position and can be wrong at any single one. For general education only; talk to a clinician or genetic counsellor before acting on anything here, and never change a prescribed medicine without your prescriber.
