Researchers surveyed 86 labs worldwide and found that although 93% used massively parallel sequencing platforms to identify variants in breast and ovarian cancer genes, 27 of the respondents mostly used Sanger sequencing to confirm genetic variants identified through other methods while six used Sanger as their only method. "Global best-practice guidelines for BRCA testing are needed to ensure consistency in testing for patients, regardless of where they obtain their testing," said study author Amanda Toland.
