UGT1A1 and Hyperbilirubinemia: Specifically, neonates harboring minor alleles of rs4148323 (known as UGT1A1*6, 211G>A) were found to have a significantly increased risk of hyperbilirubinemia (ORadj = 13.02; p = 1e-04 for UGT1A1*6 homozygote, ORadj = 2.69; p = 1e-04 for UGT1A1*6 heterozygote), whereas minor alleles at rs6742807 and (TA)n[rs8175347] were observed to have a protective effect on the risk of hyperbilirubinemia (ORadj = 0.16; p = 0.0001 for rs6742807; ORadj = 0.25; p = 0.000 for (TA)n).
