rs2981745, also known as -93C>T, is a SNP in a gene known as Deleted in Malignant Brain Tumors 1 DMBT1. The (overly descriptive?) name refers to the hypothesis that this gene has a role as a tumor suppressor.
A study of 1,195 BRCA1/2 mutation negative German breast cancer families and 1,466 unrelated German controls concluded that rs2981745(T) carriers over the age of 60 are at increased risk for breast cancer, with an odds ratio of 1.66 (CI: 1.21-2.29, p=0.0017).[PMID 19830809]
rs2981745 was also said to be tightly linked to rs11523871, which showed the same odds ratios in this study.[PMID 19830809]
