CLEC10A and cancer: Interestingly, HERVK (HML2) was not implicated in our analysis of HNSCC cancers, whereas HERVK (HML6) was identified as being significantly enriched in the downregulated set of HERVs, indicating that although the HERVK has been implicated in many other types of cancers, not all members of this superfamily of retroelements are involved in all cancers.
