Mutations to the dynamin 2 gene (DNM2) were recently associated with the autosomal dominant form of CNM while X-linked CNMs were associated with mutations in DNM2, AMPH (amphiphysin), MTM1 (myotubularin) and most recently MTMR14 (myotubularin-related protein-14) genes (Laporte et al., 1996, 2003; Jungbluth et al., 2008; Romero, 2010; Romero and Bitoun, 2011). This evidence concerns the gene AMPH and centronuclear myopathy.
