In medicine, genetic susceptibility to a disease refers to a genetic predisposition to a health problem, [1] which may eventually be triggered by particular environmental or lifestyle factors, such as tobacco smoking or diet. Genetic testing is able to identify individuals who are genetically predisposed to certain diseases.
Hereditary cancer syndromes underlie 5 to 10% of all cancers and there are over 50 identifiable hereditary forms of cancer. [5] Scientific understanding of cancer susceptibility syndromes is actively expanding: additional syndromes are being found, [6] the underlying biology is becoming clearer, and genetic testing is improving detection, treatment, and prevention of cancer syndromes.

Genotyping identifies mutations that increase susceptibility of a person to develop a disease, but disease development is not guaranteed in most cases, which can cause psychological damage. [4] Discrimination can arise from various genetic markers identified by genotyping, such as athletic advantages or disadvantages in professional sports or ...
Oncogenomics is a sub-field of genomics that characterizes cancer-associated genes.It focuses on genomic, epigenomic and transcript alterations in cancer. Cancer is a genetic disease caused by accumulation of DNA mutations and epigenetic alterations leading to unrestrained cell proliferation and neoplasm formation.
Breast cancer type 1 susceptibility protein is a protein that in humans is encoded by the BRCA1 (/ ˌ b r æ k ə ˈ w ʌ n /) gene. [5] Orthologs are common in other vertebrate species, whereas invertebrate genomes may encode a more distantly related gene. [ 6 ]
Genetic testing, genetic engineering, and stem cell research are often discussed together due to the interrelated moral arguments surrounding these topics. The distinction between repairing genes and enhancing genes is a central idea in many moral debates surrounding genetic enhancement because some argue that repairing genes is morally ...
Doctors discovered a lump during her sister's mammogram back in 2008 that came back positive for breast cancer. Genetic testing revealed both had the BRCA gene – one that puts someone at higher ...
A positive test result for a known deleterious mutation is proof of a predisposition, although it does not guarantee that the person will develop any type of cancer. A negative test result, if a specific mutation is known to be present in the family, shows that the person does not have a BRCA-related predisposition for cancer, although it does ...
