Breast Cancer-Related Low Penetrance Genes

Abstract:
Susceptibility genes involved in disease etiology and prognosis are categorized into two groups: high penetrance genes (i.e., BRCA1, CHEK2, ATM, etc.) and low penetrance genes (i.e., NATs, GSTs, CYPs, etc., and variants identified by genome-wide association studies). Since low penetrance genes have high population attributable risk, the usefulness of those genes to research on breast cancer prevention is not small. In this chapter, the previous studies on low-penetrance genetic susceptibility through a candidate gene approach and genome-wide association of breast cancer were summarized. The contribution of low-penetrance susceptibility genes to the breast cancer risk prediction models will also be discussed on the utility in clinical or public health application.

Cancer-Critical Genes II: Tumor Suppressor Genes
When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.

Loss of Tumor Suppressor Gene Functions
When the tumor suppressor genes develop mutations or are lost, cells start growing out of control, leading to cancer. However, a single functional copy of the tumor suppressor gene is enough for the cells to maintain their normal functions and cell...

The Retinoblastoma Gene
The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...
