On theoretical grounds, therefore, it should be avoided in patients with rare hereditary deficiency of hypoxanthine-guanine phosphoribosyl-transferase (HGPRT) such as Lesch-Nyhan and Kelley- Seegmiller syndrome.
Perciò teoricamente deve esserne evitato l’ utilizzo nei pazienti affetti da rare patologie ereditarie che comportano un deficit dell’ enzima ipoxantina-guanina fosforibosil-transferasi (HGPRT), come la sindrome di Lesch-Nyhan e la sindrome di Kelley-Seegmiller.
