Redundant Information in Text and Incorrect Reference

In the article titled “Association of a Novel ACTA1 Mutation With a Dominant Progressive Scapuloperoneal Myopathy in an Extended Family” published online May 4, 2015, and in the June 2015 print issue of JAMA Neurology,¹ a PMID number, which was redundant of the cited reference, appeared in the text and an incorrect reference was listed. In the second-to-last paragraph of the Discussion section, the last sentence, which read “The interacting Arg258 (labeled in reference as Arg256) has been shown²¹ to be involved in a severe nemaline myopathy (PMID: 10508519).” should be replaced with “The interacting Arg258 (labeled in reference as Arg256) has been shown²¹ to be involved in a severe nemaline myopathy.” In addition, when a PMID number was replaced by a reference during the editing process, the wrong reference was inserted. Reference 13, which read “Nowak KJ, Wattanasirichaigoon D, Goebel HH, et al. Mutations in the skeletal muscle alpha-actin gene in patients with actin myopathy and nemaline myopathy. Nat Genet. 1999;23(2):208-212.” should be replaced with “Paavilainen VO, Oksanen E, Goldman A, Lappalainen P. Structure of the actin-depolymerizing factor homology domain in complex with actin. J Cell Biol. 2008;182(1):51-59.” This article was corrected online.
