[Correlation between the mutation spectrum of the UGT1A1 gene and clinical phenotype in patients with inherited hyperunconjugated bilirubinemia].

To analyze the distribution characteristics of UGT1A1 mutant genes (including enhancers, promoters, and exons 1-5) and further explore the correlation between UGT1A1 genotype and clinical phenotypes in patients with inherited hyperunconjugated bilirubinemia.
