• Allelic Composition: Pkhd1^em1Mrug/Pkhd1⁺
• Genetic Background: involves: C57BL/6J

• ♀: phenotype observed in females
• ♂: phenotype observed in males
• N: normal phenotype

endocrine/exocrine glands

bile duct proliferation ( J:281464 )

• the number of bile ducts is increased in 13 to 17 month old mice

biliary cyst ( J:281464 )

• 13-17 month old mice show isolated liver cysts with an epithelial lining that closely resembles biliary epithelia

dilated bile duct ( J:281464 )

• 13 to 17 month old mice occasionally present with dilated biliary ducts

• however, there is minimal inflammatory infiltrates, or fibrosis of portal fields, and surrounding liver parenchyma appears intact

liver cyst ( J:281464 )

• 13 to 17 month old mice develop cystic liver that range from multiple solitary cysts to Caroli disease or congenital hepatic fibrosis-like pattern

renal/urinary system

abnormal kidney morphology ( J:281464 )

♀ • 13 to 17 month old females develop renal changes that resemble medullary sponge kidney

abnormal kidney cortex morphology ( J:281464 )

♀ • kidneys show cortical thinning in 13-17 month old females

dilated proximal convoluted tubule ( J:281464 )

♀ • 13 to 17 month old females, but not males, show ectasia of proximal tubules
