twice the average risk in the general population), and the 1 percent of
women whose lifetime risk is roughly 36 percent (about three-times
average). According to American Cancer Society guidelines, women with a
lifetime risk of 20 percent or greater should receive annual MRI breast
screenings in additional to mammograms, and women at 15 to 20 percent
lifetime risk should talk with their doctors about the benefits and
limitations of adding MRI screening to their yearly mammogram.
Target Discovery
- Bladder cancer. deCODE and colleagues in the Netherlands discovered two
common single-letter variants in the human genome (SNPs) that confer
increased risk of urinary bladder cancer. Approximately 20% of people
of European descent carry two copies of the first variant, a version of
a SNP on chromosome 8q24, putting them at a 50% higher risk of
developing bladder cancer than those without the variant. Individuals
who carry two copies of a common version of another SNP on chromosome 3
were found to be at a 40% higher risk of the disease than non-carriers.
These are the best-replicated genetic variants ever linked to bladder
cancer risk, and the study analysed genotypic data from more than
40,000 patients and controls from Iceland, the Netherlands and eight
other European countries. These findings were folded into deCODEme and
may be combined with other risk variants to develop a disease-risk
diagnostic test.
- Skin cancer. deCODE discovered common versions of two single-letter
variations in the human genome (SNPs) that confer risk of basal cell
carcinoma (BCC), the most common cancer among people of European
ancestry. Unlike the four sets of SNPs previously found by deCODE to
confer risk of BCC and cutaneous melanoma, these new variants
