Variants in the host genome may inhibit tumour growth in devil facial tumours: evidence from genome-wide association

Abstract Devil facial tumour disease (DFTD) has decimated wild populations of Tasmanian devils (Sarcophilus harrisii) due to its ability to avoid immune detection and pass from host to host by biting. A small number of devils have been observed to spontaneously recover from the disease which is othe...
