The pooled data of the two studies from India [24,33] that explored the contribution of UGT1A1 polymorphisms to the risk of neonatal hyperbilirubinemia showed significant cumulative risk estimate (OR, 4.92; 95% CI, 1.30–18.62, p = 0.019), with high heterogeneity (I2 = 74.0%). Here, UGT1A1 is linked to Hyperbilirubinemia.
