In the ELEZ group at STFU, 7 cats had persistent hyperthyroidism, including 6 with ELEZ at that time point, 5/6 (83.33%) with an ALT >100 IU/L, 2/6 (33.33%) with an ALT >500 IU/L, 4/6 (66.67%) with an ALP >100 IU/L, and none with an ALP >500 IU/L. This evidence concerns the gene GPT and hyperthyroidism.
