## Lineage
Longest line of descent: 4 generations back to DEN070009 (2007). 4 ancestors in all.
1 later device descends from it; 1 cites it directly.
0 of 6 devices in its family (counting itself) have a Class I recall.

## Predicates on the family tree (from the FDA summary)
- DEN070009: Mammaprint, Agendia BV (2007). Our reading of the summary gave K062694, which is not in FDA’s 510(k) list. The device the summary names is FDA’s De Novo DEN070009, Mammaprint (Agendia BV), granted Feb 6, 2007; older De Novo requests were first filed under a 510(k) number, so this links to the grant.

## Indications for use
The Prosigna™ Breast Cancer Prognostic Gene Signature Assay is an in vitro diagnostic assay which is performed on the NanoString nCounter® Dx Analysis System using FFPE breast tumor tissue previously diagnosed as invasive breast carcinoma. This qualitative assay utilizes gene expression data, weighted together with clinical variables to generate a risk category and numerical score, to assess a patient’s risk of distant recurrence of disease. The Prosigna Breast Cancer Prognostic Gene Signature Assay is indicated in female breast cancer patients who have undergone surgery in conjunction with locoregional treatment consistent with standard of care, either as: 1. A prognostic indicator for distant recurrence-free survival at 10 years in post-menopausal women with Hormone Receptor-Positive (HR+), lymph node-negative, Stage I or II breast cancer to be treated with adjuvant endocrine therapy alone, when used in conjunction with other clinicopathological factors. 2. A prognostic indicator for distant recurrence-free survival at 10 years in post-menopausal women with Hormone Receptor-Positive (HR+), lymph node-positive (1-3 positive nodes), Stage II breast cancer to be treated with adjuvant endocrine therapy alone, when used in conjunction with other clinicopathological factors. The device is not intended for patients with 4 or more positive nodes. Special Conditions for Use: Prosigna is not intended for diagnosis, to predict or detect response to therapy, or to help select the optimal therapy for patients.
