A study of 733 breast cancer cases for 10 SNPs concluded that the rs1501299(C;C) genotype (in dbSNP orientation) was at increased risk (odds ratio 1.80, CI: 1.14 - 2.85). After categorizing individuals by adiponectin signaling status, this study found that compared with high signalers, intermediate signalers had a 4.16-fold increase in breast cancer risk (CI: 0.49-35.19), and low signalers had a 6.56x higher breast cancer risk (CI: 0.78-54.89, p(trend) = 0.001). [PMID 18451143]
Adiponectin signaling status was assigned as follows:
rs1501299(G,G) + rs2241766(T,T) = low signaler
rs1501299(G,T) + rs2241766(T,T) = low signaler
rs1501299(G,G) + rs2241766(G,T) = low signaler
rs1501299(T,T) + rs2241766(T,T) = intermediate signaler
rs1501299(G,T) + rs2241766(G,T) = intermediate signaler
rs1501299(G,G) + rs2241766(G,G) = intermediate signaler
rs1501299(G,T) + rs2241766(G,G) = high signaler
rs1501299(T,T) + rs2241766(G,G) = high signaler
rs1501299(T,T) + rs2241766(G,T) = high signaler
Note that adiponectin, a hormone produced by adipose tissue (body fat), is involved in lipid metabolism as well as glucose regulation.
In other words, you are a low adiponectin signaler, and thus possibly at 6-fold higher risk of breast cancer, if you have one of these combinations of alleles:
You are an intermediate adiponectin signaler, and thus possibly at 4-fold higher risk of breast cancer, if you have one of these combinations of alleles:
- rs1501299 GG and also rs2241766 GG
- rs1501299 GT and also rs2241766 GT
- rs1501299 TT and also rs2241766 TT
You are a high adiponectin signaler if you have one of these combinations of alleles:
