UGT1A6 and cardiomyopathy: Carrying the A allele in the SLC28A3- rs7853758 variant was associated with a lower risk of cardiomyopathy (OR = 0.36, 95% CI: 0.22–0.60) [21], and the variant UGT1A6-rs17863783 was significantly associated with a 6.2-fold (95% CI: 2.5–15.4; p = 1.1 × 10−4) increased risk of severe cardiomyopathy [21].
