Genetics 

This recent edit added to the genetics section.

The two papers it refers to are 
Jordan CT, Cao L, Roberson EDO et al. "Rare and common variants in CARD14, encoding an epidermal regulator of NF-kappaB, in psoriasis." The American Journal of Human Genetics. April 19 2012. doi:10.1016/j.ajhg.2012.03.013.

Jordan CT, Cao L, Roberson EDO et al. "PSORS2 is due to mutations in CARD14." The American Journal of Human Genetics. April 19 2012. doi:10.1016/j.ajhg.2012.03.012.

I've added these citations to the article. Does anybody think it's too early for this? The studies were online 19/4/12 but their official publication date is 4/5/12 (according to my porous memory). I can't find any expert commentary; we may have to wait until the publication date to read the journal's editorial commentary, if there is to be any. It has appeared in a  couple of popular press articles.
