Abstract: The present invention concerns synthetic polynucleotides encoding a human fukutin-related protein (FKRP) wherein the synthetic polynucleotides contain at least a mutation avoiding supplementary transcript(s) generated from frameshift start codon(s). The synthetic polynucleotides are useful, especially for treating a pathology linked to a FKRP deficiency or induced by a defect in ?-dystroglycan (?-DG) glycosylation, such as LGMD2I.

Abstract: The present invention concerns an expression system for systemic administration comprising a sequence encoding a FKRP protein, and: a promoter sequence allowing the expression at a therapeutically acceptable level of FKRP in the skeletal muscles and a target sequence of an miRNA expressed in the heart; or a promoter sequence allowing the expression at a therapeutically acceptable level of FKRP in the skeletal muscles and presenting a promoter activity at a toxically acceptable level in the heart; and its use for the treatment of various diseases linked to FKRP deficiencies.

Abstract: The invention relates to a recombinant adeno-associated virus (AAV) capsid protein, which is a hybrid between AAV serotype 9 (AAV9) and AAV serotype 74 (AAVrh74) capsid proteins, wherein said recombinant hybrid AAV capsid protein has a reduced liver tropism compared to the parent AAV9 and AAVrh74 capsid proteins. The invention relates also to the derived hybrid AAV serotype vector particles packaging a gene of interest and their use in gene therapy, in particular for treating neuromuscular genetic diseases.
