Test Overview

Test Methodology

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.

Test Usage

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).

Reference Range

Interpretive report provided.

* Reference ranges may change over time. Please refer to the original patient report when evaluating results.
