Comparison of gene amplification between patients with BRCA1 mutations and matched patients with breast cancer unselected for family history
| Marker | BRCA1 mutation cases | Non-familial controls | p Values |
|---|---|---|---|
| HER2 amplification data were captured only for samples that were previously identified as overexpressing HER2 protein. | |||
| p Values were determined using the two tailed Fisher's exact test. | |||
| CCND1 | 0/30 | 19/74 | 0.001 |
| HER2 | 1/3 | 13/17 | 0.20 |
