Renal-hepatic-pancreatic dysplasia

What it is

From: Orphanet

Renal-hepatic-pancreatic dysplasia is a rare, genetic, developmental defect during embryogenesis syndrome characterized by the triad of pancreatic fibrosis (and cysts, with a reduction of parenchymal tissue), renal dysplasia (with peripheral cortical cysts, primitive collecting ducts, glomerular cysts and metaplastic cartilage) and hepatic dysgenesis (enlarged portal areas containing numerous elongated binary profiles with a tendancy to perilobular fibrosis). Situs abnormalities, skeletal anomalies and anencephaly have also been associated. Patients that survive the neonatal period present renal insufficiency, chronic jaundice and insulin-dependent diabetes.

Reported clinical features and what the terms mean

The following findings are associated with this condition in Orphanet. They are not a checklist for diagnosing yourself, and they do not all occur in every affected person. Some are examination, imaging or laboratory findings that cannot be recognised at home.

The frequency labels describe how often a finding was reported among people with the condition in the source. They do not give the chance that a person with that symptom has the condition. Definitions below reproduce HPO terminology; they explain the term, not the likely severity in an individual.

Hepatomegaly · Very frequent (99-80%)

Abnormally increased size of the liver.

Renal dysplasia · Very frequent (99-80%)

The presence of developmental dysplasia of the kidney.

Abnormal liver parenchyma morphology · Frequent (79-30%)

A structural anomaly of the liver located predominantly in the hepatocytes as opposed to stromal cells.

Abnormal pancreatic duct morphology · Frequent (79-30%)

Any structural anomaly of the pancreatic duct, which is the tubular structure that collects exocrine pancreatic secretions and transports them to the duodenum.

Elevated circulating alanine aminotransferase concentration · Frequent (79-30%)

An abnormally high concentration in the circulation of alanine aminotransferase (ALT).

Elevated circulating aspartate aminotransferase concentration · Frequent (79-30%)

The concentration of aspartate aminotransferase (AST) in the blood circulation is above the upper limit of normal.

Elevated gamma-glutamyltransferase level · Frequent (79-30%)

Increased level of the enzyme gamma-glutamyltransferase (GGT). GGT is mainly present in kidney, liver, and pancreatic cells, but small amounts are present in other tissues.

Enlarged kidney · Frequent (79-30%)

An abnormal increase in the size of the kidney.

Hyperbilirubinemia · Frequent (79-30%)

An increased amount of bilirubin in the blood.

Neonatal respiratory distress · Frequent (79-30%)

Respiratory difficulty as newborn.

Oligohydramnios · Frequent (79-30%)

Diminished amniotic fluid volume in pregnancy.

Pancreatic dysplasia · Frequent (79-30%)

The presence of developmental dysplasia of the pancreas.

Renal cyst · Frequent (79-30%)

A fluid filled sac in the kidney.

Renal insufficiency · Frequent (79-30%)

A reduction in the level of performance of the kidneys in areas of function comprising the concentration of urine, removal of wastes, the maintenance of electrolyte balance, homeostasis of blood pressure, and calcium metabolism.

When it may begin

From: Orphanet

Antenatal; Neonatal

Inheritance in the source

From: Orphanet

Autosomal recessive

Understanding the inheritance label

From: MedlinePlus Genetics

An autosomal recessive pattern usually involves disease-causing changes in both copies of a gene. Parents may each carry one altered copy without having the condition themselves. A genetic counsellor can explain carrier testing and reproductive implications using the actual laboratory findings, rather than the condition name alone.

Which doctor should you see?

The suggested department for discussing Renal-hepatic-pancreatic dysplasia is Clinical Genetics, with a clinical geneticist as the relevant type of clinician. Paediatrician (children) or physician (adults), with clinical geneticist referral.

Additional services that may be relevant, depending on the findings, include: Nephrology.

This is an editorial referral starting point. The appropriate clinic depends on the person’s age, symptoms, previous diagnosis and local services. The first clinician can decide whether another specialty or a team is needed; a department label does not confirm the diagnosis.

How to prepare for an assessment

Bring a short timeline of the main symptoms: when they first appeared, whether they are constant or episodic, what seems to change them, and how they affect daily activities. Include previous reports, discharge summaries, current medicines and supplements, allergies, and any relevant family history. A dated record is more useful than trying to match every feature in an online article.

Ask the clinician what is already established and what remains uncertain. If a test is suggested, ask what question it answers, what its limitations are and how the result would change the next step. The information here is not an instruction to arrange every possible test. In children, bring growth, developmental and school information if it is relevant to the concern.

• Does the exact genetic or chromosome finding explain the observed features?
• Would a genetic counsellor help the family understand the result?
• Which organ-specific assessments are appropriate for this particular diagnosis?

Treatment discussions and follow-up

The material gathered for this draft does not provide a complete condition-specific treatment pathway for Renal-hepatic-pancreatic dysplasia. That gap does not mean that treatment is unavailable. A clinician needs to establish the diagnosis and review current guidance before recommending medicines, procedures, rehabilitation or other support.

Before leaving the appointment, clarify the next review date, who will communicate results, and whom to contact if the situation changes. Discuss difficulties with sleep, work, school, mobility, eating or emotional wellbeing when these are relevant. Practical support may require coordination between the treating clinician and other services.

The collected references do not establish a complete prevention or long-term outlook section for this entry. Missing information should not be interpreted as proof that prevention is impossible or that a particular outcome is inevitable. Ask what is known for the exact subtype, stage and personal circumstances, and which uncertainties remain.

When to seek emergency help

Severe breathing difficulty, collapse, new stroke-like symptoms, a seizure that is prolonged or repeated without recovery, uncontrolled major bleeding, or an immediate risk of self-harm require emergency help. In India, call 112 or reach the nearest emergency department. This is a general, non-exhaustive warning list; it is not a condition-specific triage tool.
