For example, an oncologist or cancer geneticist may order exome or genome sequencing from a specialist cancer genetics laboratory for their patient with suspected hereditary cancer, but sequencing may identify a reportable secondary finding in a cardiovascular gene, such as KCNQ1 causing Long QT syndrome or FBN1 causing Marfan Syndrome, and vice versa. Here, FBN1 is linked to Prolonged QT interval.
