abstract |
The present application, in some embodiments, is directed to a polynucleotide including: (a) a first nucleic acid molecule including a sequence of a human endogenous Bruton's tyrosine kinase (BTK) promoter; and (b) a second nucleic acid molecule including a codon optimized sequence encoding a BTK or a functional analog thereof. Further provided are an expression vector, a cell, and a composition, all of which include the polynucleotide of the invention, and a method of using same, such as for treating X-linked Agammaglobulinemia (XLA) in a subject in need thereof. |
