Highlighting the importance of nuclear envelope proteins, mutations in genes encoding several of these proteins are associated with human diseases including Emerin (Emery-Dreifuss Muscular Dystrophy), Lamin A/C (Hutchinson-Gilford progeria syndrome) and Banf1 (Nestor-Guillermo progeria syndrome) (Worman et al., 2010). The gene discussed is SUN2; the disease is Nestor-Guillermo progeria syndrome.
