Phenotypic consequences in black South African Fanconi anaemia patients homozygous for a founder mutation
In a second report conducted in 780 patients with sporadic breast cancer (no criteria for family breast cancer), the six founder mutations
previously described were studied and it was found that mutations A1708E and 3450delCAAG in BRCA1 were positive in 2.

The founder mutations
185delAG and 5382insC in BRCA1 and 6174delT in BRCA2 appear in 60% of ovarian cancer and 30% of early-onset breast cancer patients among Ashkenazi women.
Recent studies evaluating the clonal relationships among primary and metastatic cancers have demonstrated that seeding metastases require very few additional driver or founder mutations
beyond those found in the primary tumors.

Specifically, the company launched a rapid turn-around test of the BRCA1 and BRCA2 genes combining sequencing and deletion/duplication analysis, an Ashkenazi Jewish panel for the three common Ashkenazi Jewish founder mutations
in BRCA1 and BRCA2, as well as a 26-gene panel for breast and ovarian cancer that includes BRCA1 and BRCA2.
