Clinical Information

BRAF mutations are reported in 1-4% of NSCLC diagnoses. Additionally, the common BRAF V600E mutation occurs in around 55% of BRAF-mutant NSCLC. Increased efficacy of BRAF inhibitors along with phenotypic differences from other common mutations in NSCLC, such as EGFR, has placed increased importance on BRAF mutational status (Therapeutic Advancements in Medical Oncology (2017) 9(1): 46-58). BRAFV600E-mutant NSCLC is more commonly seen in adenocarcinoma and ´┐Żnever smokers´┐Ż and has been associated with poor outcomes and reduced response to platinum-based chemotherapeutic agents. While there have been positive results from treating BRAFV600E-mutant NSCLC with targeted inhibitors, randomized controlled trials are needed to more clearly determine their efficacy (The Lancet Oncology (2016) 17(5): 642-50).


Gene sequencing and targeted mutation testing and copy number analysis can serve as a useful diagnostic and potentially prognostic tool for the analysis of affected tissues or tumors. The detection of copy number variants or specific gene mutations may enhance treatment decisions.

Specimen Requirements

Analysis can be performed on fresh or frozen tissue samples as well as formalin-fixed, paraffin-embedded tissue samples.

Transport Instructions

The specimen should be kept at the appropriate temperature and delivered via overnight shipping.

One Mother's Story

One Mother's Story

After a long three-year struggle trying to have children, our son, Charlie, was born on April 18, 2009. He was our miracle...perfect in every way! When Charlie was five days old, our pediatrician called to notify us that one of the numbers from the heel prick test was a bit high. We headed to the hospital that afternoon for more tests. I will never forget the following day. It was cool and crisp - not a cloud in the sky....
