Previous studies conducted in Asia, often comparing neonates with hyperbilirubinemia to a control group without hyperbilirubinemia, have identified UGT1A1*6 (c.211G>T) and UGT1A1*28 [A(TA)7TAA] as two common variants associated with hyperbilirubinemia (Slusher et al., 2017; Mei et al., 2022). The gene discussed is UGT1A1; the disease is Hyperbilirubinemia.
