Novel compound heterozygous PKHD1 mutations in a Chinese ARPKD pedigree and analysis of genotype-phenotype correlations

This study uncovered novel PKHD1 mutations in an ARPKD patient, expanding the pathogenic gene spectrum of ARPKD and providing insights for genetic counseling and prenatal diagnosis. Our findings also contribute to the understanding of genotype-phenotype correlations in PKHD1 mutation carriers and generate hypotheses regarding potential organ-specific thresholds for disease manifestation.
