 Mutations in the "ETV6" gene are also associated with solid tumors.In particular, the "ETV6-NTRK3" fusion gene occurs in and is thought or proposed to drive certain types of cancers.These cancers include secretory breast cancer (also termed juvenile breast cancer), mammary analogue secretory carcinoma of the parotid and other salivary glands, congenital fibrosarcoma, congenital mesoblastic nephroma, inflammatory myofibroblastic tumor, and radiation-induced papillary thyroid carcinoma.
