"Disease" and "disorder" versus "Achondroplasia"
PEGGY JEAN CASTILLO —Preceding unsigned comment added by 216.146.100.31 (talk) 20:02, 5 December 2007 (UTC)
There is a lot of debate going on as to what achondroplasia is(ie a medical condition, disorder, disease, disability, or none of the above). Because of that, I think it's a better idea just to call achondroplasia achondroplasia to prevent the article being POV. --Umalee 22:21, 31 March 2007 (UTC)
World's Smallest Girl
As reported by reputable news agency Fox News, the world's smallest girl as confirmed by the Guiness Book of World records, happens to have Achondroplasia.

Its true thats what the Fox News site says, but its incorrect. I am a doctor specialising in Achondroplasia and this person must have something else, probably primordial dwarfism.

Somebody should put some pictures up.

In other species?
I'd like to see some more on this article - namely, it's achondroplasia in other species: it's what makes dachshunds, corgis, and basset hounds (along with other breeds) long bodied with short legs. I've also seen examples of it in horses and other domesticated animals.

:lifted from: http://www.ncbi.nlm.nih.gov/pmc/articles/PMC1189626/pdf/cjvetres00008-0053.pdf
:"Based on their disproportionate dwarfism, some dog breeds traditionally have been classified as "achondroplastic." This is the case for the dachshund, basset hound, and bulldog breeds, to mention a few (4,5). Histological studies in some achondroplastic dog breeds have shown altered cell patterns in cartilage that are very similar to those observed in humans exhibiting achondroplasia (6)."

Incidence of orthopedic disability?
Aside from short stature, I wonder if and to what extent achondroplasia is accompanied by orthopedic problems, such as commonly occur in diastrophic dysplasia? These do cause disability, and if they are common in achondroplasia, that might affect the debate above about terminology. Also, if disabilities are common, the incidence (or absence of disability, if not?) would be useful to mention in the article. Wwheaton (talk) 00:40, 18 August 2010 (UTC)
:In animals, associated health issues are both severe and common (arthritis, for ex). Unfortunately I am completely unversed in related study in humans, so I would be disinclined to make these kind of changes (animal issues while perhaps pertinent would be unbalanced without accompanying human data given the structure of the article IMO). If someone has human data I can add animal data tho. Jaydubya93 (talk) 20:20, 7 March 2014 (UTC)
Why does "chondrodystrophia" redirect here?

COI edit requests
{{edit COI|answered}}
Hi, I’m a COI editor for BioMarin Pharmaceutical, the manufacturer of a treatment for achondroplasia. Requesting some updates to this article:
- In the infobox, add genetics as a risk factor, per the article lead and body.
- {{not done}} - seems redundant, since the infobox already lists genetic mutations as the cause. Spicy (talk) 05:11, 15 July 2022 (UTC)
- In the second paragraph of the lead, after
::Achondroplasia is caused by a mutation in the fibroblast growth factor receptor 3 (FGFR3) gene that results in its protein being overactive.

::*{{Done}}, but I used the Orphanet review article for this, it's better to cite a proper secondary source. Spicy (talk) 05:11, 15 July 2022 (UTC)

::*{{Done}}. Spicy (talk) 05:11, 15 July 2022 (UTC)
- In the last sentence of the second paragraph, update "symptoms" to "clinical features", which is more accurate to the language used in the [https://pubmed.ncbi.nlm.nih.gov/20301331/ source].
- {{Done}} Spicy (talk) 05:11, 15 July 2022 (UTC)

:I've responded to this after seeing {{u|MaryGaulke}}'s post at WikiProject Medicine. In the interest of transparency, and in case anyone is curious why someone would be paying for these edits (I was): BioMarin manufactures vosoritide, a drug intended to increase stature in children with achondroplasia. Some of these edits emphasize the negative effects of short stature and the current lack of effective treatments, which I suppose is where the possible bias comes in. However, the statements that I've added are supported by WP:MEDRS compliant sources. The authors of some of these sources have a declared conflict of interest with BioMarin, but comparing to other sources such as [https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6972520/] or [https://ojrd.biomedcentral.com/articles/10.1186/s13023-018-0972-6], I don't get the impression that these claims are controversial.

[[Achondroplasia in children]] merger proposal
{{Discussion top|result=To not merge, given the unique content related to children warranting separate coverage. Klbrain (talk) 15:12, 19 November 2022 (UTC)}}
Hi! As noted above, I'm a COI editor for BioMarin Pharmaceutical, the manufacturer of a treatment for achondroplasia. I’m suggesting that achondroplasia in children be merged into this article. It looks like this article is better maintained, better sourced, and more current, and I think the content is too similar to warrant a split – i.e., most folks would expect to find information about achondroplasia in children as part of this achondroplasia article. It would also be easier to ensure one article is well maintained and avoid inconsistencies between the two articles. Plus, both articles combined total approximately 34KB, not enough to justify division according to WP:SIZERULE.
Thanks for your feedback. Mary Gaulke (talk) 00:05, 7 August 2022 (UTC)
:*oppose both articles should remain separate due to specific content...IMO--Ozzie10aaaa (talk) 11:52, 22 August 2022 (UTC)
:*Oppose per Ozzie. I think the content needs to be in two separate articles, owing to the unique nature of the content relating to each age group, which would seem to me to be independently notable topics. Tom (LT) (talk) 04:13, 25 September 2022 (UTC)
