Many BRCA1 and BRCA2 genetic mutations are known to result in an elevated breast cancer risk. Routine BRCA1/2 gene screening is offered to patients thought to have an increased risk of carrying a deleterious mutation. 5-10% of genetic tests identify a variant of unknown clinical significance (VUCS), creating significant challenges to health care providers. Recent advances in sequencing technologies allow more genes to be screened in an increasing number of individuals and at an ever decreasing cost. Significantly more VUCS will be identified, adding to the uncertainty of how to manage these patients. The addition of splicing assays to current variant classification tools may be instrumental towards understanding the disease risk of these variants and improve the reliability of these assays.
