NorthShore University HealthSystem answeredThe BRAC Analysis Rearrangement Test (BART) is an additional level of analysis, which goes beyond DNA sequences of genes. BART looks for large rearrangements, deletions, and insertions of DNA material. A positive BART result has the same medical implications as a mutation found with more routine types of analysis. Anyone who has had comprehensive BRCA1/2 testing could go on for BART analysis. It is a matter of yield (chances of finding a mutation), and cost. For high-risk families (multiple cases of breast cancer; early-onset usually; often ovarian cancer in the family), the yield is 1-3%. The cost is $650.
