1. A gene therapy vector comprising a nucleic acid construct comprising: a nucleic acid encoding a stabilized form of an alpha-galactosidase A (α-GAL) protein comprising one or more non-native cysteine residues that form a disulfide bridge between non-native cysteines within the protein or between non-native cysteines of two monomers of the protein, wherein the α-GAL protein comprises the non-native cysteine residues D233C and 1359C relative to the wildtype α-GAL sequence (SEQ ID NO: 1).
