The journal apologises for an error that has occurred within the abstract of this paper, which should read as follows:

There may be a link between diseases caused by polyglutamine and polyalanine expansion mutations as it has been shown that the expanded CAG/polyglutamine tract within the SCA3 gene can shift to the GCA/polyalanine frame.
