In this review, we searched PubMed for articles on the genetic causes of NUH published before December 31, 2022, and analyzed the data. On the basis of the results, we reached eight conclusions: (1) 37 mutations of the <em>G6PD</em> gene are associated with NUH; (2) the clinical manifestation of G6PD deficiency depends not only on ethnicity but also on the molecular mechanisms underlying the deficiency (and thus its severity); (3) of mutations in the <em>UGT1A1</em> gene, homozygous c.−53A(TA)₆TAA &gt; A(TA)₇TAA is the main cause of NUH in Caucasians and Africans, whereas homozygous c.211G &gt; A is the main genetic cause of NUH in East Asians; (4) in Indonesian neonates, homozygous c.−3279T &gt; G is the most common cause of NUH development, and neither c.−53 A(TA)₆TAA &gt; A(TA)₇TAA nor c.211G &gt; A causes it; (5) in breast-fed East Asian neonates, the TA7 repeat variant of the <em>UGT1A1</em> gene protects against the development of NUH; (6) G6PD deficiency combined with homozygous c.211G &gt; A variation of the <em>UGT1A1</em> gene increases the risk of severe NUH; (7) in Pakistani and Caucasian patients with Crigler–Najjar syndrome type 2 (CN-2), point mutations of the <em>UGT1A1</em> gene are widely distributed and frequently occur with variation at nucleotide −53, whereas in Asian patients with CN-2, compound homozygous variations in the coding region are frequently observed; and (8) records of G6PD deficiency and <em>UGT1A1</em> variation status for a neonate offer useful pharmacogenomic information that can aid long-term care.
