On page 320 of this article, “mutant mice that are hypomorphic for the ribosomal protein L22 show specific defects in translation of related Hox mRNAs” should have read “mutant mice that are hypomorphic for the ribosomal protein L38 show specific defects in translation of related Hox mRNAs”. This has been corrected in the online version.
