Another study screened for the presence of the BRAF mutation in 667 canine tumours, including a series of haematopoietic tumours (n = 245), sarcomas (n = 160), carcinomas (n = 115), melanocytic tumours (n = 72), as well as other, less common cancers (n = 75). The gene discussed is BRAF; the disease is sarcoma.
