Autosomal recessive polycystic kidney disease (ARPKD) is a rare, inherited condition in which a baby is born with very small, fluid-filled sacs (micro-cysts) spread throughout the kidneys. These micro-cysts make both kidneys become very large, dense, and brighter than usual on ultrasound. ARPKD can already damage kidney function in the womb. It also almost always involves the liver, where abnormal bile ducts and scarring cause congenital hepatic fibrosis. Because ARPKD is recessive, a child is affected only when they receive one faulty copy of the same gene from each parent. The main gene is PKHD1, which encodes a cilia-related protein called fibrocystin (polyductin). Problems in fibrocystin disturb how kidney tubules and bile ducts form and maintain their shape, leading to cysts, high blood pressure, reduced kidney function, and liver-related complications from infancy through childhood.

Autosomal recessive polycystic kidney disease is a rare genetic disease that starts in the womb or early childhood. Kidneys enlarge with many tiny cysts and often struggle to work. Most children also develop congenital hepatic fibrosis (CHF) in the liver, which can lead to portal hypertension (high pressure in the portal vein) and complications like enlarged spleen or varices (swollen veins in the esophagus). There is no proven, curative medicine today; treatment focuses on protecting kidney and liver function, controlling blood pressure, preventing infections/bleeding, nutrition, dialysis if needed, and (when appropriate) transplant.

Another names
People may use several names for the same condition. Knowing them helps when you read test reports or research papers:
Infantile polycystic kidney disease – a historical term that reflects how often ARPKD is found before birth or in early life. NIDDK
ARPKD-PKHD1 – a genetics-first label used in GeneReviews that ties the diagnosis to the PKHD1 gene. NCBI
ARPKD with congenital hepatic fibrosis (ARPKD/CHF) – used when the liver component is emphasized. NCBI
Fibrocystic kidney–liver disease (pediatric type) – a broader descriptive phrase used in clinical reviews and rare-disease summaries. NCBI+1
Types
ARPKD is one disease, but it shows different patterns. Doctors often describe types by age at first signs and by which organ’s problems dominate at a given time.
1) By age at presentation
Perinatal / prenatal type. Detected on pregnancy ultrasound: both kidneys are very enlarged and bright, often with low amniotic fluid (oligohydramnios). Severe cases can cause underdeveloped lungs (pulmonary hypoplasia). AJOG+1
Infantile type (0–12 months). Babies present with big kidneys, high blood pressure, poor feeding, and salt-water balance issues. NCBI
Childhood / adolescent type. Children may have slower kidney decline but develop more obvious liver problems such as portal hypertension, enlarged spleen, and cholangitis. NCBI
2) By organ predominance
Kidney-predominant. Early renal enlargement, hypertension, concentrating defects, and chronic kidney disease (CKD). NIDDK
Liver-predominant. Features of congenital hepatic fibrosis: stiff scarred liver, enlarged spleen, low platelets from hypersplenism, and bile duct infections. NCBI
Causes
ARPKD is genetic. The “causes” below explain what creates the disease and what modifies how severe it looks. Each item is a short, plain paragraph to clarify the biology in easy terms.
Biallelic PKHD1 pathogenic variants. ARPKD happens when a child inherits two faulty PKHD1 copies (one from each parent). This is the fundamental cause. NCBI+1
Autosomal recessive inheritance. Parents are usually healthy “carriers.” Each pregnancy has a 25% chance to be affected if both parents carry a PKHD1 variant. womenshealth.labcorp.com
Loss of fibrocystin (polyductin) function. Faulty PKHD1 means the kidney and bile-duct cells lose a cilia protein needed to shape tubules and ducts. The result is malformed, cystic structures. MedlinePlus
Missense variants. A single amino-acid change can weaken fibrocystin, sometimes allowing milder kidney disease but stronger liver involvement—yet severity is variable. NCBI
Truncating variants (nonsense/frameshift). These often stop the protein early and are linked to more severe, early disease. NCBI
Splice-site variants. Abnormal RNA splicing yields defective or unstable protein, contributing to classic ARPKD. NCBI
Compound heterozygosity. Many children carry two different PKHD1 variants; their combination shapes the phenotype. NCBI
Large deletions/insertions. Less common structural changes in PKHD1 can abolish gene function. MedlinePlus
Ciliary signaling defects. Fibrocystin lives in primary cilia; ciliary signaling failure drives cyst growth and ductal malformation. NCBI
Abnormal planar cell polarity. Tubular cells lose their coordinated “alignment,” which encourages round cyst formation instead of straight tubules. NCBI
Ductal plate malformation of the liver. During fetal life, bile ducts fail to remodel correctly, later causing congenital hepatic fibrosis. NCBI
Increased cell proliferation in collecting ducts. Kidney collecting duct cells multiply abnormally, expanding micro-cysts throughout the medulla and cortex. NCBI
Disrupted fluid transport. Faulty cilia signaling alters ion/water handling, contributing to dilated tubules and poor concentrating ability. NCBI
Endoplasmic reticulum stress and misfolding. Some variants misfold fibrocystin, leading to cellular stress and progressive tissue injury. NCBI
Modifier genes / background variation. Genetic background outside PKHD1 can shift severity and organ emphasis (kidney vs liver). NCBI
Consanguinity (parental relatedness). Increases the chance both parents carry the same PKHD1 variant, raising risk to offspring. GARD Information Center
Oligohydramnios sequence effects. While not the root cause, very low amniotic fluid from poor fetal kidney function worsens lung development and outcomes. AJOG
Bile duct ectasia and cholangitis loops. Recurrent bile-duct infections and stasis accelerate liver scarring in genetically affected children. NCBI
Hypertension-induced renal injury. High blood pressure appears early in ARPKD and itself speeds kidney damage, worsening the genetic disease course. NIDDK
Progressive CKD biology. Chronic inflammation, fibrosis, and nephron loss amplify the original genetic defect over time, eventually leading to kidney failure. NIDDK
Symptoms and signs
Enlarged abdomen in the newborn. Very large kidneys push the abdomen outward; parents notice a “full tummy.” NIDDK
Breathing problems at birth. Low amniotic fluid and large kidneys can compress the chest and impair lung development, causing respiratory distress. AJOG
High blood pressure (early hypertension). Common in infancy/childhood due to kidney salt-water handling changes. NIDDK
Poor feeding and vomiting. Babies may struggle to feed and gain weight, especially if kidneys cannot balance salts and acid well. NIDDK
Frequent urination and thirst. A concentrating defect makes dilute urine; children drink and urinate more. NCBI
Urinary tract infections. Structural changes and poor flow can raise UTI risk. NCBI
Blood in urine (hematuria). Fragile cystic tubules and high pressure can leak blood cells into urine. NCBI
Chronic kidney disease (CKD). Gradual fall in kidney function, sometimes needing dialysis or transplant in childhood. NIDDK
Growth delay. CKD and poor nutrition slow height and weight gain. NIDDK
Liver enlargement and stiffness. Congenital hepatic fibrosis causes a firm liver on exam and higher liver stiffness on imaging. NCBI
Portal hypertension signs. Big spleen, low platelets, and dilated veins (varices) can appear as liver scarring progresses. NCBI
Cholangitis (bile-duct infection). Fever, pain, and jaundice episodes occur due to malformed bile ducts and poor drainage. NCBI
Pruritus (itching). Bile-flow problems can cause itching, especially during cholestasis flares. NCBI
Abdominal pain or fullness. Stretched capsule and organ enlargement can cause discomfort. NIDDK
Fatigue and pallor. CKD-related anemia and chronic illness reduce energy and cause pale skin. NIDDK
Diagnostic tests
A) Physical examination (bedside)
Blood pressure measurement. Hypertension is common and can appear early; measuring BP at every visit is essential. NIDDK
Abdominal inspection and palpation. Large, firm kidneys raise abdominal girth; the liver edge may feel firm; the spleen may be enlarged later. NCBI
Growth assessment. Tracking weight, length/height, and head circumference shows nutrition and CKD impact over time. NIDDK
Edema check. Periorbital or peripheral swelling can occur in advanced kidney disease with salt-water retention. NIDDK
B) Manual bedside tests (simple clinic tools)
Fundoscopy (retina exam). Looks for hypertensive retinopathy in children with persistent high BP. NIDDK
Abdominal percussion for organ size. Helps corroborate kidney and liver enlargement when imaging is pending. NCBI
Assessment for ascites (fluid wave). Suggests portal hypertension or severe liver involvement in older children. NCBI
C) Laboratory and pathological tests
Serum creatinine and eGFR. Define kidney function and CKD stage; trends guide timing of dialysis or transplant. NIDDK
Serum electrolytes and acid–base panel. Detects sodium/potassium problems and metabolic acidosis from tubule dysfunction. NIDDK
Urinalysis with microscopy. Looks for blood, protein, and concentrating defects; supports cystic kidney disease assessment. NIDDK
Urine osmolality and sodium. Confirms poor concentrating ability and helps manage fluids and salt. NIDDK
Liver function tests (bilirubin, ALP, GGT, ALT/AST). Evaluate congenital hepatic fibrosis and cholestasis; GGT can be elevated with bile-duct disease. NCBI
CBC and platelets. Low platelets may reflect hypersplenism from portal hypertension; anemia is common in CKD. NCBI+1
Coagulation profile (PT/INR). Assesses liver synthetic function and bleeding risk before endoscopy or surgery. NCBI
Blood cultures during fever with jaundice. Important when cholangitis is suspected to guide antibiotics. NCBI
Genetic testing for PKHD1. Confirms diagnosis, clarifies recurrence risk, and supports prenatal counseling for families. NCBI+1
Pathology (when performed). Liver biopsy shows congenital hepatic fibrosis (ductal-plate malformation and portal fibrosis); kidney tissue is rarely needed. NCBI
D) Electrodiagnostic and related monitoring
Electrocardiogram (ECG). Detects dangerous rhythms from high potassium or severe hypertension—important in advanced CKD or acute illness. NIDDK
E) Imaging tests
Prenatal ultrasound. Classic picture: both kidneys are very enlarged and hyperechogenic with poor corticomedullary differentiation; cysts are tiny; amniotic fluid may be low. These findings can appear in the late second or third trimester. AJOG+1
Postnatal renal ultrasound. Shows large, bright kidneys packed with small micro-cysts; helps track size and echotexture over time. NIDDK
Doppler ultrasound of the portal venous system. Assesses signs of portal hypertension from congenital hepatic fibrosis (e.g., splenic vein enlargement). NCBI
MRCP / liver MRI. Maps bile-duct abnormalities, evaluates fibrosis, and helps plan management of cholangitis or portal hypertension. NCBI
Voiding cystourethrogram (selected cases). Looks for vesicoureteral reflux if infections are recurrent—useful in pediatric cystic kidneys with UTIs. NIDDK
Chest imaging (when respiratory issues present). Evaluates lung development in severe perinatal cases or complications from large abdominal organs. AJOG
