Ideal sources for Wikipedia's health content are defined in the guideline Wikipedia:Identifying reliable sources (medicine) and are typically review articles. Here are links to possibly useful sources of information about Chronic progressive external ophthalmoplegia. PubMed provides review articles from the past five years (limit to free review articles) The TRIP database provides clinical publications about evidence-based medicine. Other potential sources include: Centre for Reviews and Dissemination and CDC

Progressive external ophthalmoplegia appears to cover the same ground as this article. As I understand it the terms are interchangeable, but 'CPEO' is a common abbreviation in speech and writing in British neurology, and this article is more detailed. I would therefore propose merging PEO into CPEO. Thoughts? Neurotip ( talk) 17:29, 27 March 2010 (UTC) reply

I concur, as this is also the term used in Clinical Neurology, 3rd ed. by Fowler and Scadding. -- Eleassar ^{my talk} 19:26, 2 April 2010 (UTC) reply

I also concur. -- Arcadian ( talk) 19:41, 2 April 2010 (UTC) reply

'Tis done. I've tried to avoid changing the text (as I believe is etiquette for a merge), but it was hard as a lot of this is written badly and in places I can hardly make sense of it. I'll put it on my to do list, but others' contributions are welcome. I couldn't restrain myself from writing a new lead section though. Neurotip ( talk) 00:38, 25 April 2010 (UTC) reply

The ANT1 link on this page points to a Greek TV network; no page for the gene exists on this site as of this comment. Pikalax 22:48, 20 April 2017 (UTC) — Preceding unsigned comment added by Pikalax ( talk • contribs)

It now links to the enzyme made by ANT1 — also known as SLC25A4. PriceDL ( talk) 23:46, 20 April 2017 (UTC) reply
