PCLD4 is an autosomal dominant disease characterized by adult-onset of liver cysts arising from the bile duct epithelium. Some patients may develop a few kidney cysts, but these are often incidental and do not result in renal failure (summary by Cnossen et al., 2014).
For a discussion of genetic heterogeneity of polycystic liver disease, see PCLD1 (174050). [from
