This was consistent with Chou’s observations [25], but was somewhat inconsistent with the results of a similar study in Taiwanese neonates by Huang et al. [22], who showed that UGT1A1 *6 was also a risk factor of neonatal hyperbilirubinemia in neonates who were not fed with breast milk. This evidence concerns the gene UGT1A1 and Hyperbilirubinemia.
