However, in human patients, many of the specific NSTs are associated with specific germline or somatic mutations and occur as part of familial tumor syndromes—neurofibromatosis type 1 (NF1), neurofibromatosis type 2 (NF2), and schwannomatosis [24]—while in veterinary medicine, data on genetic disorders associated with the occurrence of neoplasms are still sparse. This evidence concerns the gene NF2 and hereditary disease.
