Nonfamilial Genetic Testing for Breast Cancer Risk Assessment

DESCRIPTION

A number of single nucleotide variants (SNVs), which are single base-pair variations in the DNA sequence of the genome, have been associated with breast cancer and are common in the population, but confer only small increases in risk. Commercially available assays purportedly test for a number of SNVs and predict an individual’s risk of breast cancer relative to the general population. Some of these assays incorporate clinical information into risk prediction algorithms. The intent of this type of test is to identify subjects without a family history of breast cancer who may be at increased risk due to single nucleotide variants and may benefit from more intensive surveillance.

Examples of genetic testing assays for non-familial breast cancer risk assessment include but are not limited to BREVAGen™and BREVAGenplus.

Note: This policy does not address testing for BRCA1, BRCA2, PALB2, TP53 or PTEN single gene variants associated with inherited breast cancer.

POLICY

IMPORTANT REMINDERS

ADDITIONAL INFORMATION

There is a lack of high-quality evidence to determine if SNV-based risk assessment has any impact on health care outcomes. The U.S. Preventive Services Task Force and American Cancer Society recommend mammography for breast cancer screening in average risk individuals.
