Novel recurrent cases were also found in ovarian (n = 6), endometrial (n = 2) and breast (n = 2) cancers involving CCDC6, a coiled-coil domain protein, fusing with ANK3 at the 3′ end, which encodes the ankyrin G protein that plays a key role in cell proliferation, as result of tandem duplications (Fig. 4a). Here, CCDC6 is linked to cancer.
