Key facts

Inherited liver disease at a glance.

The essentials in plain English, from the commonest inherited pattern to the rare specialist commissioned conditions.

  • What it is

    A family of inherited conditions that damage the liver directly or through metabolic overload, ranging from benign to life-limiting.

  • Most common

    Haemochromatosis (HFE) and Gilbert syndrome (UGT1A1) are the two most frequent inherited conditions affecting the liver in the UK.

  • Rare and serious

    Wilson disease, alpha-1 antitrypsin deficiency, tyrosinaemia, PFIC and urea cycle disorders need specialist commissioned care.

  • How they present

    Some show in infancy as jaundice or failure to thrive, others as adult cirrhosis, iron or copper overload, or an incidental blood-test finding.

  • How they are diagnosed

    A combination of history, family screen, disease-specific bloods, imaging, FibroScan and genetic testing through NHS Genomic Medicine Service panels.

  • Why genetics matters

    Confirming the gene guides treatment, unlocks cascade testing for relatives and opens reproductive options where relevant.

Why this guide matters

A shared framework for a very diverse family.

Genetic liver disease is not one condition. The three points below shape how UK hepatologists approach the whole group.

  • Think early in cryptogenic disease

    Unexplained cirrhosis, a young person with abnormal LFTs or infant cholestasis should always trigger a genetic workup.

  • Confirm the gene, not just the pattern

    NHS Genomic Medicine Service panels and WES/WGS give a specific answer, which changes treatment and unlocks cascade testing.

  • Use specialist commissioned services

    Wilson, tyrosinaemia, PFIC, urea cycle and storage disorders are managed through nationally commissioned centres in the UK.

How the diagnosis is made

From first blood test to a specific gene.

The steps a UK GP, hepatologist or clinical geneticist will normally follow, in order.

  1. 01

    Assessing

    History and family screen

    A detailed personal and three-generation family history, focused on liver disease, unexplained jaundice, neurological symptoms and consanguinity.

  2. 02

    Assessing

    Baseline liver bloods

    LFTs, INR, albumin, full blood count and a metabolic panel to see how the liver is coping and what pattern of injury is present.

  3. 03

    Assessing

    Disease-specific biochemistry

    Iron studies, caeruloplasmin and 24-hour urinary copper, alpha-1 antitrypsin level and phenotype, ammonia, bilirubin fractions and AFP as indicated.

  4. 04

    Confirming

    Imaging and FibroScan

    Ultrasound, MRI or MRCP where relevant, and transient elastography (FibroScan) to quantify fibrosis and steatosis non-invasively.

  5. 05

    Confirming

    Specialist hepatology review

    Referral to a UK hepatology centre with experience in inherited liver disease, often a specialist commissioned service for the rarer conditions.

  6. 06

    Genetics

    Genetic panel or WES/WGS

    Targeted panel testing, whole exome or whole genome sequencing through the NHS Genomic Medicine Service, with clinical genetics input.

  7. 07

    Genetics

    Cascade testing and counselling

    Once a gene is confirmed, first-degree relatives are offered cascade testing, with reproductive counselling where the condition is serious.

Typical timeline: a first hepatology clinic to a confirmed gene in weeks to a few months.

Main conditions

The genetic liver conditions to know.

A hub of the commonest and most important inherited liver conditions in the UK, with links to dedicated guides where we have them.

  • Haemochromatosis (HFE)

    Iron overload from HFE variants, most often C282Y homozygous. Fatigue, arthralgia, bronzed skin, diabetes and cirrhosis. See our haemochromatosis guide.

  • Wilson disease (ATP7B)

    Copper accumulation causing liver disease and neuropsychiatric symptoms. Kayser-Fleischer rings, tremor, dystonia and behavioural change. Specialist commissioned care.

  • Alpha-1 antitrypsin deficiency (SERPINA1)

    PiZZ phenotype can cause cirrhosis in adults and children and emphysema in adults. Augmentation therapy is available for lung disease.

  • Gilbert syndrome (UGT1A1)

    A benign, common cause of mild unconjugated hyperbilirubinaemia. Jaundice with fasting, illness or stress. Reassurance is the mainstay.

  • Crigler-Najjar (UGT1A1)

    A rare severe unconjugated hyperbilirubinaemia presenting in infancy. Type 1 needs phototherapy and often liver transplantation.

  • Dubin-Johnson and Rotor

    Benign conjugated hyperbilirubinaemia with normal liver architecture. Mild jaundice, no specific treatment required.

  • HHT (Osler-Weber-Rendu)

    Autosomal dominant vascular disease from ENG, ACVRL1 and related genes. Epistaxis, telangiectasia and hepatic vascular malformations.

  • Red flag - infant jaundice or acute liver failure

    Persistent neonatal jaundice, acute liver failure at any age or a young adult with neurological change plus liver blood-test derangement needs urgent specialist referral.

Also in this hub

Polycystic liver disease from PKD1, PKD2, PRKCSH and SEC63 variants. Hereditary tyrosinaemia from FAH deficiency treated with nitisinone through a specialist commissioned metabolic service. Urea cycle disorders, glycogen storage disorders and lysosomal storage disorders such as Gaucher disease and Niemann-Pick. Neonatal cholestatic syndromes including Alagille (JAG1, NOTCH2) and progressive familial intrahepatic cholestasis (PFIC) driven by BSEP, MDR3 and FIC1. Galactosaemia and hereditary fructose intolerance. Cystic fibrosis liver disease. Hereditary liver cancer risk in Li-Fraumeni syndrome and other familial cancer syndromes, all managed with specialist commissioned oversight.

Treatment

How genetic liver conditions are treated in the UK.

Treatment is condition-specific, from venesection and chelation to enzyme replacement, targeted diets and transplantation.

  • Haemochromatosis

    Venesection to normalise ferritin and transferrin saturation, then maintenance. Screen relatives with HFE genotyping. See our haemochromatosis guide.

  • Wilson disease

    Lifelong chelation with penicillamine or trientine, plus zinc as maintenance. Managed through a specialist commissioned metabolic and hepatology service.

  • Alpha-1 antitrypsin deficiency

    Smoking cessation is critical. Augmentation therapy is available through the alpha-1 antitrypsin augmentation clinic for selected lung disease. Liver transplantation for end-stage cirrhosis.

  • Gilbert and Dubin-Johnson

    Reassurance and lifestyle advice. No specific drug therapy needed. See our Gilbert syndrome guide.

  • Crigler-Najjar

    Phenobarbital in type 2, intensive phototherapy in type 1, and liver transplantation for definitive treatment.

  • Hereditary tyrosinaemia

    Nitisinone plus a low-tyrosine and low-phenylalanine diet, delivered by a specialist commissioned metabolic service. Liver transplantation if hepatocellular carcinoma develops.

  • Urea cycle and storage disorders

    Protein-restricted diets, ammonia scavengers, enzyme replacement therapy where available and specialist commissioned metabolic follow-up.

  • Neonatal cholestatic syndromes

    Alagille (JAG1, NOTCH2) and PFIC (BSEP, MDR3, FIC1) are managed by paediatric hepatology, with ursodeoxycholic acid, ileal bile acid transporter inhibitors and sometimes transplantation.

Cross-cutting principles

Every family with a confirmed inherited liver condition should have access to genetic counselling and cascade testing through the NHS Genomic Medicine Service. Reproductive counselling, including pre-implantation genetic testing where eligible, is arranged through clinical genetics. Long-term follow-up with FibroScan, LFTs and disease-specific biochemistry is standard, and hepatocellular carcinoma surveillance is added where risk is high. Transition from paediatric to adult hepatology is planned early for conditions presenting in childhood.

Red flags

When inherited liver disease needs urgent attention.

These are the presentations that must not sit in primary care, and where specialist commissioned services are needed.

  • Neonatal prolonged jaundice

    Conjugated jaundice beyond two weeks of age needs urgent paediatric hepatology assessment for biliary atresia, Alagille and PFIC.

  • Acute liver failure

    Any patient with rapidly rising bilirubin, coagulopathy or encephalopathy needs immediate transfer to a UK transplant centre.

  • Young adult with neuropsychiatric change

    Tremor, dystonia, dysarthria or personality change with abnormal LFTs in someone under 40 must prompt urgent Wilson disease screening.

  • Cirrhosis without an obvious cause

    Cryptogenic cirrhosis in a young or middle-aged adult should trigger genetic testing for haemochromatosis, alpha-1 antitrypsin deficiency and Wilson disease.

  • Family history of liver transplantation

    Especially in siblings or children, is a strong signal for cascade genetic testing through the NHS Genomic Medicine Service.

  • Hepatocellular carcinoma at a young age

    HCC before 40, or on a non-cirrhotic liver, raises suspicion of hereditary tyrosinaemia, glycogen storage disease or a familial cancer syndrome such as Li-Fraumeni.

  • Recurrent epistaxis with liver findings

    Hereditary haemorrhagic telangiectasia can cause hepatic arteriovenous malformations, high-output cardiac failure and biliary ischaemia.

  • Multiple liver cysts

    Polycystic liver disease from PKD1, PKD2, PRKCSH or SEC63 variants can cause massive hepatomegaly and needs specialist review.

  • Cystic fibrosis liver disease

    Persistent transaminase rise, portal hypertension or nodular liver in a person with CF needs hepatology input alongside CF specialists.

Living with it

A lifelong plan, shared with your family.

Four things that make the biggest difference day to day, from protecting the liver to keeping specialist follow-up on track.

A quiet reminder

Cascade testing can be life-changing for relatives.

Many people diagnosed early with haemochromatosis or Wilson disease will live a normal length of life, provided they start treatment before organ damage sets in.

  1. 01 Alcohol

    Protect the liver from extra hits

    Avoid alcohol, unnecessary paracetamol overuse and herbal supplements. Discuss any new medication with your hepatologist.

  2. 02 Family

    Cascade testing matters

    Once a gene is confirmed, first-degree relatives should be offered testing. Early treatment prevents damage in haemochromatosis and Wilson disease.

  3. 03 Follow-up

    Long-term specialist review

    Most genetic liver conditions need lifelong follow-up with FibroScan, LFTs, disease-specific bloods and cancer surveillance where relevant.

  4. 04 Support

    You are not alone

    British Liver Trust, Wilson Disease Support Group UK, Alpha-1 UK Support Group and Genetic Alliance UK all offer peer support and information.

Frequently asked

Everything we get asked about genetic liver conditions.

Quick answers on diagnosis, specialist services, cure, cascade testing and pregnancy.

  • What counts as a genetic liver condition?

    Any inherited condition that primarily damages the liver, or damages it through a metabolic pathway, counts. This includes haemochromatosis, Wilson disease, alpha-1 antitrypsin deficiency, Gilbert syndrome, Crigler-Najjar, Dubin-Johnson and Rotor syndromes, hereditary haemorrhagic telangiectasia, polycystic liver disease, tyrosinaemia, urea cycle and glycogen storage disorders, some lysosomal storage diseases, neonatal cholestatic syndromes such as Alagille and PFIC, galactosaemia, fructosaemia and cystic fibrosis liver disease.

  • How are genetic liver conditions diagnosed in the UK?

    The workup starts with history, family screen and standard liver bloods, then adds disease-specific biochemistry such as iron studies, caeruloplasmin, urinary copper, alpha-1 antitrypsin level and phenotype, bilirubin fractions and AFP. Imaging and FibroScan quantify liver damage. Genetic confirmation is by targeted panel, whole exome sequencing or whole genome sequencing through the NHS Genomic Medicine Service, usually in a specialist hepatology clinic.

  • Which conditions need a specialist commissioned service?

    Wilson disease, hereditary tyrosinaemia, urea cycle disorders, glycogen storage diseases, lysosomal storage disorders such as Gaucher and Niemann-Pick, PFIC and hereditary liver cancer syndromes are managed through NHS England specialist commissioned services with combined hepatology, metabolic medicine, clinical genetics and transplant input.

  • Can genetic liver conditions be cured?

    A few can be controlled so well that people live an essentially normal life. Haemochromatosis responds fully to venesection when caught early, Wilson disease is controlled with lifelong chelation and zinc, and tyrosinaemia can be transformed by nitisinone. Others such as PFIC, Crigler-Najjar type 1 and end-stage cirrhosis of any cause may need liver transplantation for cure.

  • Should my relatives be tested if I have a confirmed diagnosis?

    Usually yes. Cascade testing of first-degree relatives is standard for haemochromatosis, Wilson disease, alpha-1 antitrypsin deficiency, HHT, polycystic liver disease and the rarer metabolic conditions. Clinical genetics services in the UK coordinate this, alongside reproductive counselling for couples planning a family.

  • What about pregnancy and inherited liver disease?

    Pre-pregnancy counselling with clinical genetics and hepatology is important. Options include natural conception with prenatal testing, pre-implantation genetic testing through NHS-commissioned centres for eligible conditions, or the use of donor gametes. Medications also need review before conception, especially chelators, nitisinone and immunosuppression after transplantation.
