Is polycystic liver disease dominant or recessive?

Inheritance pattern of polycystic liver disease is autosomal dominant. A single mutated copy of the responsible gene is enough to cause hepatic cysts, which is why this condition often runs in families with affected individuals across generations and shows variable severity. Genes such as PRKCSH and SEC63 are linked to autosomal dominant polycystic liver disease, explaining cyst formation in the liver even when kidney involvement is minimal or absent. This dominant pattern contrasts with X-linked or mitochondrial inheritance, which follow different transmission routes, and with recessive inheritance, which typically requires two mutated copies and a different family pattern.
