The <i>LMNA</i> gene encodes the A-type lamins, which polymerize into ∼3.5-nm-thick filaments and, together with B-type lamins and associated proteins, form the nuclear lamina. Mutations in <i>LMNA</i> cause a wide variety of pathologies. In this study, we analyzed the nuclear lamina of embryonic fibroblasts from <i>Lmna</i><sup>H222P/H222P</sup> mice, which develop cardiomyopathy and muscular dystrophy. Although the organization of the lamina appeared unaltered, there were changes in chromatin  ...[more]
