Title Real-time allele-specific amplification for sensitive detection of the BRAF mutation V600E.
Abstract Text BRAF is a cytoplasmic serine/threonine kinase in the MAPK pathway that transduces signals from RAS family members to MEK1/2. Mutations in the BRAF gene have been described in the majority of cutaneous melanomas, papillary thyroid carcinoma and to a lesser extent in other cancers. The predominant mutation reported is a single transversion in exon 15 (T1799A). We designed a real-time allele-specific PCR to detect this mutation. This assay allowed us to detect this alteration in samples containing 2% of cells harboring this mutation, which is equivalent to 1% mutated DNA, assuming heterozygosity for the allele. Using this assay, we then tested 44 human primary colorectal tumors. We found the V600E mutation in four samples (9.1%). Analysis of DNA extracted from paraffin-embedded sections gave similar results, indicating that archived tissues can also be analyzed using this assay. The advantages of this method include: (1) rapidity; (2) sensitivity; (3) ease; (4) large throughput; (5) low cost and (6) the small quantities of DNA needed.


  • Case insensitive filtering will display rows if any text in any cell matches the filter term
  • Use simple literal full or partial string matches
  • Separate multiple filter terms with a space. Any order may be used (i. e. a b c and c b a are equivalent )
  • Filtering will only apply to rows that are already loaded on the page. Filtering has no impact on query parameters.
  • Use quotes to match on a longer phrase with spaces (i.e. "mtor c1483f")


  • Generally, the default sort order for tables is set to be first column ascending; however, specific tables may set a different default sort order.
  • Click on any column header arrows to sort by that column
  • Hold down the Shift key and click multiple columns to sort by more than one column. Be sure to set ascending or descending order for a given column before moving on to the next column.
