Reference list searches identified an additional study which was previously excluded as the abstract did not specifically mention HDAC6, however presented data suggested that the reported outcomes were relevant to the current review and the full text for this article was therefore screened.44 The full text of 68 articles were screened, of which 61 were excluded most commonly because they did not investigate the effect of HDAC6 inhibition on AIS outcomes. Here, HDAC6 is linked to androgen insensitivity syndrome.
