The genetic testing company Color Genetics [13] has created a cancer panel for breast and ovarian cancers that include the genes ATM, BARD1, BRCA1, BRCA2, BRIP1, CDH1, CHEK2, EPCAM, MLH1, MSH2, MSH6, NBN, PALB2, PMS2, PTEN, RAD51C, RAD51D, STK11, and TP53. Doctors can perform a biopsy of a patient’s tumor and send the formalin-fixed, paraffin-embedded (FFPE) tissue sample to a diagnostic company for targeted exome sequencing. Here, CHEK2 is linked to cancer.
