Supplementary Table 3 contained two incorrectly predicted phenotypes based on the described genetic variant combinations (rs number variants). Supplementary Table 3 has been simplified and updated accordingly.

Supplementary Table 3 Genotype to predicted phenotype translation to be programmed into laboratory information system.

This table includes UGT1A1 alleles with a minor allele frequency ≥ 1% in either the White, African or Asian population.

According to the allele definition table of PharmGKB, there is no allele including two of the polymorphisms (https://www.pharmgkb.org/haplotype/PA166115865, accessed on 16 December 2022). This suggests that alleles including two or more of these polymorphisms are either very rare or non-existent. For this reason, genotypes with 3 or 4 polymorphisms were not included in the translation table. In addition, in compound heterozygotes, both polymorphisms were considered to be on different alleles.
