Abstract

To explore the genetic basis for a fetus with autosomal recessive polycystic kidney disease (ARPKD). Fetal tissue and peripheral blood samples were respectively obtained from the abortus and the couple. Following extraction of genomic DNA, genetic testing was carried out. The fetus was found to carry compound heterozygous variants of the PKHD1 gene, namely c.5336A>T (p.N1779I) and c.9455delA (p.N3152Tfs*10), which were respectively inherited from the husband and wife. The c.5336A>T and c.9455delA variants of the PKHD1 gene probably account for the ARPKD in the fetus. Above results have enabled genetic counseling and prenatal diagnosis for the couple.
