BRCA1 and BRCA2 mutation analysis is performed by next-generation sequencing of all coding exons of the BRCA1 and BRCA2 genes to detect point mutations and small insertions/deletions. This test does not detect large deletions or duplications.
FFPE tissue: Paraffin block is preferred. Alternatively, send 1 H&E slide plus 5-10 unstained slides cut at 5 or more microns. Please use positively-charged slides and 10% NBF fixative. Do not use zinc fixatives.
Use cold pack for transport. Make sure cold pack is not in direct contact with specimen.
