Autosomal recessive polycystic kidney disease (ARPKD) is caused primarily by pathogenic variants in PKHD1, encoding fibrocystin/polyductin. In Cys1cpk/cpk (cpk) mice, the kidney and liver lesions closely phenocopy ARPKD. Cys1 encodes cystin, a myristoylated protein that traffics to the primary cilium and nucleus. We recently reported the first patient with ARPKD due to a homozygous CYS1 splicing variant.
