The Rise of MRD Testing and the Field of Fragmentomics with Sugganth Daniel, Invitae

"There's an entire field of fragmentomics with a whole lot of people working on it. The DNA which is shed into the bloodstream has a certain length. The length of ctDNA is shorter than cfDNA, and depending on where the cancer cell is located, the fragment size and pattern is different. So you can actually deduce information about the tissue of origin from the fragment length and pattern. And that's just the beginning."
