Test Overview
Targeted sequencing of the BRCA1 and BRCA2 genes is performed by amplifying the regions containing these founder mutations using specific primers, and bidirectionally sequencing them using a fluorescent method.
Three Ashkenazi Jewish founder mutations can be detected by this targeted sequencing assay: BRCA1 gene c.68_69delAG (BIC: 185delAG) and c.5266dupC (BIC: 5382insC) and one in BRCA2 c.5946delT (BIC: 6174delT). Note: MMGL will report out these mutations using the current Human Genome Variation Society (HGVS) naming guidelines instead of the previous nomenclature determined by Breast Cancer Information Core (BIC).
