Tumor Genetic Testing Summary We summarize here strategies to adopt when testing individuals for BRCA1 and BRCA2 mutations based on positive or negative family history. Any comments or personal experiences are welcome in the comments section. For an introduction on the BRCA1 and BRCA2 genes, you can read our BRCA1 and BRCA2 deep dive page here or our clinical card on hereditary
Current Methods for BRCA1/BRCA2 molecular analysis BRCA testing is commonly performed by direct Sanger sequencing. This method is considered the ‘gold standard’ of DNA sequencing. It is technologically reliable, widely available, and has a relatively simple workflow. The drawbacks of Sanger sequencing are: • limited throughput • lower cost-effectiveness compared to next-generation sequencing (NGS) •
