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. For more information, see the PubMed Commons FAQ.

PTPRJ mutation

Buffart et al. in this paper affirm that they found a mutation (Glu836Asp) in PTPRJ gene. They reported the sequence of the region surrounding the mutation and, indeed, the sequence perfectly matches with that of exon 13 that includes a well known polymorphism of PTPRJ (Asp872Glu, SNP ID rs 4752904). Thus, also in this case, as correctly reported for the other two polymorphisms of PTPRJ, the authors detected a polymorphism and not a mutation of PTPRJ.
