Ten percent of human hereditary diseases are linked to nonsense mutations (premature termination codon). These mutations lead to premature translation termination, trigger the synthesis of a truncated protein and possibly lead to mRNA degradation by the NMD pathway (nonsense mediated mRNA decay). For the past ten years, therapeutic strategies have emerged which attempt to use molecules that facilitate tRNA incorporation at premature stop codon (readthrough), thus allowing for the synthesis of a full length protein. Molecules currently used for this approach are mostly aminoglycoside antibiotics (gentamicin, amikacin...) that bind the decoding center of the ribosome. This therapeutic approach has been studied for various genetic diseases including Duchenne muscular dystrophy (DMD) and cystic fibrosis. The feasibility of this approach depends on induced readthrough level, mRNA quantity, re-expressed protein functionality and characteristics of each disease.
