ABSTRACT
OBJECTIVE@#To explore the genetic basis for a fetus featuring infantile polycystic kidney disease (IPKD).@*METHODS@#Following elective abortion, fetal tissue and peripheral blood samples of its parents were collected for the extraction of genomic DNA. Whole exome sequencing was carried out to detect potential variants correlated with the phenotype.@*RESULTS@#The fetus was found to harbor a heterozygous c.1370C>T (p.P457L) variant of the HNF1B gene, which was unreported previously. The same variant was not detected in either parent.@*CONCLUSION@#The heterozygous c.1370C>T (p.P457L) variant of the HNF1B gene probably underlay the IPKD in this fetus. Above finding has enabled genetic counseling and prenatal diagnosis for the family.
