Motivation: The eClaus model can be used to calculate mutation risks for BRCA1/2 as well as life-time risks for breast cancer in women from families with multiple and/or early onset cases of breast and ovarian cancer. The model can be used to assist genetic counselors in clinical decision making regarding genetic testing, intensified surveillance, and prophylatic surgery.

Description: The Claus model is a genetic breast cancer risk calculation model assuming a single rare, highly penetrant gene. ...

Motivation: The "Manchester Scoring System" can be used to assist clinicians and genetic counselors in the clinical management of families suspected of having hereditary breast and ovarian cancer and to decide whether genetic testing should be performed.

Description: The "Manchester Scoring System" is an empirical mutation risk prediction model. In its current form, a risk score for the identification of a pathogenic BRCA1/2 mutation is being calculated based on the number of breast and ovarian ...

Motivation: The "GC-HBOC Mutation Frequency Explorer" can be used to assist clinicians and genetic counselors in the clinical management of families suspected of having hereditary breast and ovarian cancer and to decide whether genetic testing should be performed.

Description: The "GC-HBOC Mutation Frequency Explorer" is a tool to determine the observed frequencies of pathogenic BRCA1 and BRCA2 mutations based on familial cancer history data collected since 1996 by the German Consortium for ...
