Variegate porphyria can appear at any age, but symptoms usually begin in adulthood. It is important for those with this condition to work closely with healthcare providers to manage symptoms and reduce the risk of complications.

Causes of Variegate porphyria

Variegate porphyria is a genetic disorder caused by a mutation in the protoporphyria gene. This gene provides instructions for making an enzyme called protoporphyrinogen oxidase, which is essential for the production of heme. Heme is a component of hemoglobin, the protein in red blood cells that carries oxygen. When there is a mutation in the protoporphyria gene, the enzyme cannot function properly, leading to a buildup of certain molecules called porphyrins in the body. These accumulated porphyrins are toxic and can cause damage to tissues and organs.

Common triggers for variegate porphyria symptoms include alcohol consumption, certain medications, hormonal changes, and exposure to sunlight. These triggers can disrupt the heme production process in individuals with the genetic mutation, causing a flare-up of symptoms such as abdominal pain, skin blistering, and neurological problems. It is important for individuals with variegate porphyria to avoid these triggers as much as possible to help manage their condition and prevent worsening of symptoms.

Who is affected by it

Variegate porphyria can affect anyone, regardless of age or gender. It is an inherited condition, meaning that people are born with it because of a genetic mutation passed down from their parents. This condition primarily impacts the production of heme, a crucial component of hemoglobin that carries oxygen in the blood. When heme production is disrupted, symptoms of variegate porphyria can arise, such as skin blistering, abdominal pain, and neurological issues. People with this condition may experience varying degrees of severity in their symptoms, depending on environmental factors and other health conditions they may have.

Types of Variegate porphyria

There are three types of variegate porphyria (VP): familial type, South African type, and non-South African type. Familial type VP is usually found in people of European descent and is inherited through a gene passed down from a parent. South African type VP is more common in people of South African descent and is caused by a different gene mutation. Non-South African type VP is found in people of various ethnicities and may be due to different genetic mutations.

All types of VP have similar symptoms, such as abdominal pain, skin fragility, and neurological issues. Treatment for VP involves managing symptoms with pain medication, avoiding triggers like certain medications or stress, and sometimes receiving intravenous heme therapy to help reduce porphyrin levels in the body. Proper medical management and avoiding triggers can help people with VP lead healthier lives.
