Description
Technical Field
The invention belongs to the technical field of gene variation detection, and particularly relates to a BRCA1/2 gene variation combined detection kit and application thereof.
Background
In 1990, researchers discovered a gene closely related to hereditary breast cancer, named as breast cancer gene No. 1 (BRCA1), and located on chromosome 17; after 4 years, researchers have found another gene associated with breast cancer on chromosome 13, called BRCA2, both of which are commonly referred to collectively as BRCA 1/2.
BRCA is a cancer suppressor gene, and plays an important role in regulating cell replication, DNA damage repair and normal cell growth; if the BRCA gene is mutated, the function of inhibiting tumorigenesis is lost. The BRCA mutation types are hundreds of types, and are associated with the occurrence of many cancers in humans, the most closely related being breast cancer, followed by ovarian cancer.
Breast cancer is one of the common malignant tumors of women, the incidence rate of which is the first female tumor, and about 50 ten thousand women die of breast cancer every year worldwide. Breast cancer is the result of multifactorial, polygenic and environmental co-action, and its familial inheritance has long been recognized. Studies have found that 5% to 10% of breast cancer patients have familial aggregative and genetic predisposition. Numerous studies have shown that families with the germline BRCA1 mutation exhibit a higher susceptibility to breast cancer: the female has a lifetime risk of breast cancer of 80% to 90% and the age of the patient is significantly reduced. The risk of breast cancer in carriers of BRCA2 gene mutation is similar to that of BRCA1 mutant, and is also 80% -90%.
Presumably, about 25 to 50 million carriers of BRCA1/2 gene mutation are among more than 3 hundred million Americans. The BRCA gene mutation carrying rate in the general population is 1/400-600, while in some specific populations the BRCA mutation carrying rate is as high as 1/40-50, such as German Uygur, Iceland and Fancao. The BRCA1/2 gene mutation carrying situation in Chinese population is not clear, and is generally considered to be lower than that in the United states and northern Europe countries.
According to the BIC database (Breast Cancer Information Core, http:// research. nhgri. nih. gov/BIC /), the currently reported types of mutations of BRCA1 and BRCA2 genes include nonsense mutations, frameshift mutations, non-frameshift insertions, non-frameshift deletions, missense mutations, synonymous mutations, splice site mutations, and deletion or rearrangement of large fragments, and these mutations are spread over nearly 4000 mutation sites, and there is no evidence that there are regions of mutation hotspots, and only a few relatively high frequency mutation sites. Although the BRCA1/2 gene has variation and cannot be judged to have breast cancer, the detection of the BRCA gene of the breast cancer can indicate that individuals have risks of breast cancer and ovarian cancer, and the physical conditions of the individuals are known in advance. The targeted professional prevention is carried out on high-risk individuals, for example, the intervention is carried out by taking some targeted medicines, and the preventive stripping/removing operation is carried out. And carrying out accurate treatment on the diagnosed cancer. At present, Sanger sequencing, qPCR (quantitative polymerase chain reaction) or MLPA (MLPA) are mainly used as methods for detecting BRCA1/2 gene mutation, but the methods have low sequencing flux and low sensitivity, and need a large amount of time and are not expensive.
