Abstract

Background In recent years the theoretical hope has become reality and the first hereditary neuromuscular diseases have become causally treatable. Neuromuscular diseases have thus become the pacemaker of this form of therapy for the whole of neurology. Aims This article describes the principles of precision gene therapy for neurogenetic diseases using examples of neuromuscular diseases. Discussion Various strategies of gene therapy have become established and are being tested in preclinical and clinical trials and evaluated as approved forms for long-term efficacy. The aim of every gene therapy is the modification or introduction of the target gene with initiation of a degradation of dysfunctional proteins. Various techniques, such as gene transfer, gene substitution or gene editing in vivo and ex vivo are now usable. For example, a modification of the pre-mRNA using antisense oligonucleotides or RNA interference (siRNA) can be used for exon skipping. An initiation of gene expression to produce the target protein can be based on a modification of the DNA by means of gene replacement, cell-based therapy (iPS cells), regulation by compensatory proteins or pharmacological treatment with so-called small molecules. Each method has advantages and complex disadvantages that must be individually evaluated. Phenotypic peculiarities of a rare disease often only become apparent through specific translational therapy. It is already becoming obvious that a very early point in timing of gene therapy is probably the most effective. Newborn screening is therefore gaining additional importance as early diagnosis can achieve the best possible success of therapies, possibly even preventively.
