PKHD1 and autosomal recessive polycystic kidney disease: ADPKD results from pathogenic variants in the PKD1 (OMIM *601313) and PKD2 (OMIM *173910) genes located on chromosomes 4 and 16, respectively (Reddy & Chapman, 2017), while ARPKD is caused by mutations in the PKHD1 (OMIM *606702) gene on chromosome 6 (Hartung & Guay‐Woodford, 2014).
