The two main forms of PKD are autosomal dominant PKD (ADPKD) and autosomal recessive PKD (ARPKD) which are caused by mutations in PKD1 or PKD2 (encoding polycystin‐1 and ‐2) and PKHD1 (encoding for fibrocystin), respectively (Bergmann et al., 2018). This evidence concerns the gene PKHD1 and autosomal recessive polycystic kidney disease.
