Abstract:
With the increasing of the incidence rate of breast carcinoma year after year, the susceptibility genes of breast carcinoma was paid more and more attention. The study on susceptibility genes play an important role in early diagnosis and prevention for the individuals with family history of breast carcinoma, elucidation of pathologic mechanism of sporadic breast carcinoma, early diagnosis and adjudging prognosis, research on drug sensitivity, differential diagnosis of benign and malignant disease, etc. There were many studies on the high-penetrance susceptibility genes (BRCA1, BRCA2). However, some low-penetrance susceptibility gene, for example, the members of hormone metabolism related enzymes genes CYP family (CYP17, CYP19, CYP1A1, etc.), the carcinogen metabolism related gene (GSTM1, NAT1, NAT2), and DNA damage repair gene (ATM) were not clearly understood. The aim of this study was to review the present research situation of common susceptibility genes of breast carcinoma found already.

Cancer-Critical Genes I: Proto-oncogenes
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.

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,...
