Deletion of Autosomal chromosome epigenetic silencing to cure Down syndrome

Comment: The current article lacks secondary sources to support the material that are recommended by ; this is synthesis of several primary sources, with heavy reliance on a single http://www.uff.br/neurociencias/images/artigos_selecao/Luiz_Leao_2014.pdf August 2013 study in ''Nature''. It's a very important, groundbreaking study, but is preliminary, foundational research that probes what it refers to as "the major first step towards potential development of 'chromosome therapy'". Merging elsewhere is inappropriate; medical topics are treated differently than other subjects on Wikipedia, and coverage of proposed medical cures should generally be referenced with secondary sources, not individual studies (primary sources). Rationale and details for the different treatment are discussed in  and its Talk page archives. If secondary sources can be found with substantial information on this approach, it may warrant an article, but I didn't find any; the ''Nature'' article is recent, and while it has been widely cited in medical literature, it does not seem to have been cited in any reviews yet.
