Hutchinson-Gilford Progeria Syndrome (HGPS) is a rare human genetic disease caused by mutations in the LMNA gene. LMNA codes for structural components of the nuclear lamina. Alterations of nuclear lamina lead to a very variable class of diseases known as laminopathies. In detail, HGPS manifests a severe premature ageing phenotype due to the accumulation of a dominant negative form of lamin-A called progerin. With current treatments, the life expectancy of HGPS patients does not exceed their second decade. Death is usually due to cardiovascular complications. Recently, a new technology for mammals in vivo gene editing has been developed: the clustered regularly interspaced short palindromic repeats/Cas protein (CRISPR/Cas) system. The CRISPR/Cas technology permits to edit the genome at specific loci. Even if the CRSIPR/Cas constructs are transiently administered to the target cells, the genome editing is permanent. The advantages of the combination of non-integrating transient vectors in combination with the CRISPR/Cas constructs could give rise to a secure approach for the treatment of disease of genetic origin, especially those caused by dominant negative mutations, such as HGPS. A potential application of non-integrating transient vectors carrying CRISPR/Cas constructs for the treatment of HGPS will be discussed in detail.
