Purpose Of Review:
To summarize advances in next-generation sequencing and their application to breast and gynecologic cancer risk assessment.
Recent Findings:
Next-generation sequencing panels of 6-112 cancer-associated genes are increasingly used in patient care. Studies report a 4-16% prevalence of mutations other than BRCA1/2 among patients who meet evidence-based practice guidelines for BRCA1/2 testing, with a high rate (15-88%) of uninterpretable variants of uncertain significance. Despite uncertainty about results interpretation and communication, there is early evidence of a benefit from multiple-gene sequencing panels for appropriately selected patients.
Summary:
Multiple-gene sequencing panels appear highly promising for the assessment of breast and gynecologic cancer risk, and they may usefully be administered in the context of cancer genetics expertise and/or clinical research protocols.

When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.
Such genes that act...
