Thus most individuals with Rett syndrome are females, presumably because the male version is usually not viable.

I removed this sentence because MECP2 mutations are viable in male embryos. I wrote Rett syndrome#Gender and Rett syndrome to deal with this. Out of curiosity, has anyone done an article on embryonic lethality? Thanks, anonymous IP 203.34.41.146 23:59, 23 October 2005 (UTC)

[edit] Proposed merge and rename

I would like to merge this article with autosomal and re-name it autosomal versus X-linked inheritance. sex linkage, sex chromosome, autosomal chromosome, and autosomal would redirect to autosomal vs X-linked inheritance. Right now, Sex chromosome incorrectly forwards to sex determination system. autosomal dominant is already proposed for a merge into dominance relationship which is where most of it belongs. I'll just take what I need for autosomal vs sex-linked inheritance and put the rest in dominance relationship Dr d12 21:54, 9 December 2006 (UTC) hi ppl!!!!

Merging these articles as proposed seems like a bad idea to me. In the first place, organisms other than humans have letters other than X and Y designating their sex chromosomes. For example, birds use a ZW sex determination system, and many organisms use an XO system, where O stands for the absence of a chromosome. There can be Y-linked inheritance as well. How would we integrate bees, wasps and ants into this system, when a male's genome consists of half of a females autosomes, meaning that all or none of their chromosomes are sex chromosomes? Furthermore, a look at the scientific literature reveals that sex chromosomes are the source of far more richness than just a "versus" the autosomal chromosomes. Webofscience finds 5,228 articles with "x chromosome" in their title, 1,623 articles with "sex chromosome" in their title, and 395 with "autosome" in the title. Only 58 articles use the term x (or sex) chromosome in a title with the term autosome. Speciate 06:26, 7 January 2007 (UTC)speciate

I don't think there is a real need to merge the articles. They're quite important/individual topics. I think a summary off this could come under the dominance relationship. But no need for merging.Ziphon 05:39, 17 May 2007 (UTC)

[edit] Lfesch-Nhgnyhan sygndrome

Is this a misspell or does it really exist? I googled it and couldn't find a Lfesch-Nhgnyhan syndrome ... the Nhgnyhan is a surname that's usually spelled Ngnyan Svizac 20:07, 1 June 2007 (UTC)
