| breast cancer susceptibility genes | Inherited factors that predispose to breast cancer. Put otherwise, these genes make one more susceptible to the disease and so increase the risk of developing breast cancer. Two of these genes, BRCA1 and BRCA2, have been identified (and prominently publicised). Several other genes (those for the Li-Fraumeni syndrome, Cowden disease, Muir-Torre syndrome, and ataxia-telangiectasia) are also known to predispose to breast cancer. However, since all of these known breast cancer susceptibility genes together do not account for more than a minor fraction (1/5th at most) of breast cancer that clusters in families, it is clear that more breast cancer genes remain to be discovered.

| genes | Located in the nucleus of the cell, genes contain hereditary information that is transferred from cell to cell. (09 Oct 1997) |
| genes, abl | Retrovirus-associated DNA sequences (abl) originally isolated from the abelson murine leukaemia virus (ab-mulv). The proto-oncogene abl (c-abl) codes for a protein that is a member of the tyrosine kinase family. The human c-abl gene is located at 9q34.1 on the long arm of chromosome 9. It is activated by translocation to bcr on chromosome 22 in chronic myelogenous leukaemia. (12 Dec 1998) |
| genes, apc | Tumour suppressor genes located in the 5q21 region on the long arm of chromosome 5. The mutation of these genes is associated with familial adenomatous polyposis (apc stands for adenomatous polyposis coli) and gardner's syndrome, as well as some sporadic colourectal cancers.
