Pharmacogenomic advances have increased understanding of allopurinol-associated severe cutaneous adverse reactions (SCARs), demonstrating that HLAB*5801 is a strong risk factor for their development. In some populations, all patients with allopurinol-induced SCARs carry this allele. New treatment recommendations outline how this discovery should influence gout therapy, particularly the use of allopurinol.
