Retraction Notice to: VMA21 Deficiency Causes an Autophagic Myopathy by Compromising V-ATPase Activity and Lysosomal Acidification

This article has been retracted. Please see Elsevier Policy on Article Withdrawal (http://www.elsevier.com/locate/withdrawalpolicy). Reason: Our paper reported the identification of mutations in the gene VMA21 in patients with X-linked Myopathy with Excessive Autophagy (XMEA) and characterized the molecular mechanisms underlying the disease phenotype. Many of the figure panels in the paper summarize data from multiple experiments. We have now detected a number of errors in these panels. While we stand by the validity of our conclusions, we believe that the most responsible course of action is to retract our paper. We are preparing an expanded version of our work for future submission. We deeply regret this circumstance and apologize to the community. One of the original authors, Dr. Aubourg, could not be reached regarding this retraction.
