Hepatic porphyria
Porphyria is a group of rare conditions. They are caused by a problem with how the body makes blood. Some of these conditions are called acute hepatic porphyria (AHP). They can sometimes cause liver disease.
The information on this page is for:
- Adults and children with hepatic porphyria or suspected hepatic porphyria.
- Family, friends, carers, and healthcare professionals.
This information is about liver conditions caused by hepatic porphyria. But there are lots of other types of porphyria. All types of porphyria can have a wide range of symptoms not linked to the liver.
You can get more information about all types of porphyria from The British Porphyria Association.

What is hepatic porphyria?
Porphyria is the name for a group of rare conditions. They are caused by a problem when a molecule called haem is made.
Doctors call porphyria hepatic porphyria if that problem happens in the liver.
They call other types of porphyria erythropoietic porphyria.
Porphyria is also grouped by the problems it causes:
- Acute porphyria leads to sudden attacks of symptoms like severe pain. It can also cause ongoing symptoms.
- Cutaneous porphyria can cause severe skin problems.
Types of hepatic porphyria
There are 4 different types of hepatic porphyria:
- acute intermittent porphyria (AIP)
- 5-aminolevulinic acid (ALA)
- dehydratase deficiency porphyria (ADP)
- hereditary coproporphyria (HCP)
What causes porphyria?
What normally happens?
Haem is part of the haemoglobin molecule that carries oxygen in blood. It is made from parts called porphyrins. These are put together in a complicated process with lots of different steps. These steps need special proteins called enzymes. The instructions to make the enzymes are in your genes.
What happens in porphyria?
If there is a mistake in the gene, the enzyme will not be made properly. This means the process of making haem will get stuck. The haem will not be made properly. So the porphyrins can build up and cause problems.
How does hepatic porphyria affect the liver?
Not everyone with hepatic porphyria will develop liver problems. Other symptoms are likely to appear first and may be far more significant. However, in some cases, hepatic porphyria causes liver damage.
Liver disease and cirrhosis
Liver damage from porphyria builds up very slowly over many years. In the early stages, there are no symptoms, and most people will not know it is happening.
Over time, this damage can sometimes lead to serious liver damage called cirrhosis.
Cirrhosis is a late stage in many different types of liver disease. You can use the links below to find out more.

Liver cancer
Hepatic porphyria raises the risk of a rare cancer called hepatocellular carcinoma (HCC).
Because hepatic porphyria is so rare, it is hard to say exactly how big the risk is. Some recent studies tracked groups of people with hepatic porphyria for several years. They found that for every 100 people with hepatic porphyria:
- 1 or 2 developed HCC
- 98-99 did not develop HCC

If you have hepatic porphyria, you might have regular tests (surveillance) to check for HCC. This may depend on your age. Talk to your medical team if this is something you may want.

Hemin treatment and liver damage
A treatment called hemin is sometimes used for acute porphyria attacks. If this treatment is needed a lot, it can sometimes cause iron to build up in the liver and cause damage.
Liver transplant
In very rare cases, a person with hepatic porphyria may be considered for a liver transplant.
A new liver will be able to make haem normally and should stop all the symptoms of hepatic porphyria. But it is a very big operation with a lot of risks and lifelong issues. So it is only considered for people who have severely disabling attacks. And when all other treatment options have failed.
