Background: Few studies have focused on the relationship of exonic variation with breast cancer and subtypes defined by tumor markers: estrogen receptor (ER), progesterone receptor (PR), and HER2.Methods: We genotyped 1,764 breast cancer patients and 1,400 controls from the California Teachers Study cohort using the Infinium HumanExome Beadchip. Individual variant and gene-based analyses were conducted for overall breast cancer and by individual tumor marker subtype.Results: No exonic variants or gene-based analyses were statistically significantly associated with breast cancer overall or by ER-, PR-, or HER2-defined subtype.Conclusions: We did not detect any novel statistically significant exonic variants with overall breast cancer risk or by subtype.Impact: Exonic variants in the exome chip may not be associated with overall breast cancer or subtype susceptibility.

Breast cancer risk is influenced by rare coding variants in susceptibility genes, such as BRCA1, and many common, mostly non-coding variants. However, much of the genetic contribution to breast cancer...
Childhood cancer survivors treated with chest-directed radiotherapy have substantially elevated risk for developing breast cancer. Although genetic susceptibility to breast cancer in the general popul...
Clustering of breast and colorectal cancer has been observed within some families and cannot be explained by chance or known high-risk mutations in major susceptibility genes. Potential shared genetic...
Reproductive aging phenotypes, including age at menarche (AM) and age at natural menopause (ANM), are well-established risk factors for breast cancer. In recent years, many genetic variants have been ...
Genome-wide association studies (GWAS) have identified more than 90 susceptibility loci for breast cancer, but the underlying biology of those associations needs to be further elucidated. More genetic...
This study will analyze blood samples to identify substances that are associated with the development of breast cancer. It will determine if: - Women who are diagnosed with a benign b...
Breast cancer is a disease of complex origin with a strong genetic component. The incidence of breast cancer is very high in monozygotic twins of patients, and it is thought that a high pr...
RATIONALE: Studying mammograms for breast density changes over time may help doctors predict breast cancer risk. PURPOSE: This natural history study is looking at changes in breast densit...
The investigators propose to study the association of the KCNJ11 (Potassium Voltage-Gated Channel Subfamily J Member 11) polymorphisms on diabetes risk in the Atherosclerosis Risk in Commu...
The purpose of this study is to investigate and analyse genomic profiles in patient with breast cancer who failed standard treatment, refractory and young breast cancer.
Autosomal dominant HEREDITARY CANCER SYNDROME in which a mutation most often in either BRCA1 or BRCA2 is associated with a significantly increased risk for breast and ovarian cancers.
A synthetic retinoid that is used orally as a chemopreventive against prostate cancer and in women at risk of developing contralateral breast cancer. It is also effective as an antineoplastic agent.
Abnormal accumulation of lymph in the arm, shoulder and breast area associated with surgical or radiation breast cancer treatments (e.g., MASTECTOMY).
Metastatic breast cancer characterized by EDEMA and ERYTHEMA of the affected breast due to LYMPHATIC METASTASIS and eventual obstruction of LYMPHATIC VESSELS by the cancer cells.
A hereditary disease characterized by multiple ectodermal, mesodermal, and endodermal nevoid and neoplastic anomalies. Facial trichilemmomas and papillomatous papules of the oral mucosa are the most characteristic lesions. Individuals with this syndrome have a high risk of BREAST CANCER; THYROID CANCER; and ENDOMETRIAL CANCER. This syndrome is associated with mutations in the gene for PTEN PHOSPHATASE.
Bioinformatics is the application of computer software and hardware to the management of biological data to create useful information. Computers are used to gather, store, analyze and integrate biological and genetic information which can then be applied...
