| Abstract |
Altered DNA methylation of imprinted genes has been implicated in a range of cancers. Imprinting is established early in development, and some are maintained throughout the life course in multiple tissues, providing a plausible mechanism linking known early life factors to cancer risk. This study investigated methylation status of seven imprinted differentially methylated regions-PLAGL1/ZAC1, H19-ICR1, IGF2-DMR2, KvDMR-ICR2, RB1, SNRPN-DMR1 and PEG3-in blood samples from 189 women with the most common type of invasive breast cancer (invasive ductal carcinoma-IDC), 41 women with in situ breast cancer (ductal carcinoma in situ-DCIS) and 363 matched disease-free controls. There was no evidence that imprinted gene methylation levels varied with age (between 25 and 87 years old), weight or height. Higher PEG3 methylation was associated with an elevated risk of IDC (odds ratio (OR) 1.065; 95 % confidence interval (CI) 1.002, 1.132; p = 0.042) and DCIS (OR 1.139; 95 % CI 1.027, 1.263; p = 0.013). The effect was stronger when in situ and invasive breast cancer were combined (OR 1.079; 95 % CI 1.020, 1.142; p = 0.008). DCIS breast cancer risk increased with higher KvDMR-ICR2 methylation (OR 1.395; 95 % CI 1.190, 1.635; p < 0.001) and lower PLAGL1/ZAC1 methylation (OR 0.905; 95 % CI 0.833, 0.982; p = 0.017). In a combined model, only KvDMR-ICR2 methylation remained significantly associated. These findings may help to improve our understanding of the aetiology of breast cancer and the importance of early life factors in particular. Imprinting methylation status also has the potential to contribute to the development of improved screening and treatment strategies for women with, or at risk of, breast cancer. |

Attention Score in Context
This research output has an Altmetric Attention Score of 7. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 06 November 2015.
All research outputs
#4,433,612
of 22,826,360 outputs
Outputs from Clinical Epigenetics
#289
of 1,256 outputs
Outputs of similar age
#57,012
of 267,016 outputs
Outputs of similar age from Clinical Epigenetics
#15
of 47 outputs
Altmetric has tracked 22,826,360 research outputs across all sources so far. Compared to these this one has done well and is in the 80th percentile: it's in the top 25% of all research outputs ever tracked by Altmetric.
So far Altmetric has tracked 1,256 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 6.5. This one has done well, scoring higher than 76% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 267,016 tracked outputs that were published within six weeks on either side of this one in any source. This one has done well, scoring higher than 78% of its contemporaries.
We're also able to compare this research output to 47 others from the same source and published within six weeks on either side of this one. This one has gotten more attention than average, scoring higher than 68% of its contemporaries.
