PubMed Commons is an experimental system of commenting on PubMed abstracts, introduced in October 2013. Comments are displayed on the abstract page, but during the initial closed pilot, only registered users can read or post comments. Any researcher who is listed as an author of an article indexed by PubMed is entitled to participate in the pilot. If you would like to participate and need an invitation, please email info@biomedcentral.com, giving the PubMed ID of an article on which you are an author.

Dear Editor,

In a recently published article in the BMC Medical Genetics (2007, 8:3) Sofia Mayans and colleagues definitely prove a lack of association between CTLA-4 gene CT60 single nucleotide polymorphism (SNP) and serum level of soluble CTLA-4 (sCTLA-4). This is an interesting and valuable paper. However, in the Discussion, the Authors say that their results "are supported by data from Anjos et al.(2002) who also found no effect of the CT60 polymorphism on the expression of sCTLA-4". In the matter of fact, Anjos et al. did not study CT60 at all, but only +49A>G SNP. In contrast, the lack of effect of CT60 on sCTLA-4 serum levels was described earlier by Purohit et al (2005) who is cited by Mayans et al., but only for the lack of association of the sCTLA-4 level with type 1 diabetes.
