We therefore hypothesise that the high hTERC RNA levels found in the eutopic endometrium of women with the benign proliferative disease, endometriosis, may facilitate the postulated increased proliferative potential of these cells, which may also be a reflection of increased TA, but dyskerin may not play a major role in the pathology of endometriosis. The gene discussed is DKC1; the disease is endometriosis.
