5q-associated spinal muscular atrophy is one of the most severe and common genetic
diseases. In the last few years, innovative methods of therapy have been developed based
on SMN2 gene modification, such as splicing, or replacement of the damaged SMN1 gene
(gene replacement therapy, GRT). GRT is known to be accompanied by off target effects like
temporary elevation of liver and cardiac enzymes usually without serious clinical relevance.
