GALT and Mayer-Rokitansky-Kuster-Hauser syndrome: As a result, the genetic association of MRKH with galactosemia [66] or with cystic fibrosis [67] was analyzed, but neither the gene for galactose-1-phosphate uridyl transferase (GALT) [68] nor the gene encoding the cystic fibrosis transmembrane regulator (CFTR) chloride channel [67] showed any mutation or polymorphism associated with the disorder.
