What is Familial Porphyria Cutanea Tarda?

Familial Porphyria Cutanea Tarda (FPCT) is a rare genetic disorder affecting the skin and liver. It occurs due to a deficiency in the enzyme uroporphyrinogen decarboxylase (UROD). This enzyme is crucial for heme production, a component of hemoglobin.

FPCT is a type of porphyria: Porphyria refers to a group of disorders caused by abnormalities in the chemical steps leading to heme production.
Inherited condition: FPCT is passed down through families, typically in an autosomal dominant pattern.
Enzyme deficiency: The disorder stems from a lack of UROD enzyme, leading to the buildup of porphyrins in the body.
Affects both skin and liver: Symptoms can include skin sensitivity to sunlight and liver dysfunction.

Symptoms of Familial Porphyria Cutanea Tarda

FPCT symptoms can vary widely among individuals. They often manifest in the skin and liver, causing significant discomfort and health issues.

Blistering skin: Sun exposure can cause painful blisters, especially on the hands and face.
Hyperpigmentation: Skin may darken or develop brown patches.
Fragile skin: Skin becomes more prone to injury and slow to heal.
Excessive hair growth: Some individuals experience increased hair growth on the face and other areas.
Liver problems: Liver dysfunction can lead to symptoms like fatigue, abdominal pain, and jaundice.

Causes and Risk Factors

Understanding the causes and risk factors of FPCT can help in managing and potentially preventing flare-ups.

Genetic mutation: A mutation in the UROD gene is the primary cause.
Alcohol consumption: Excessive drinking can exacerbate symptoms.
Iron overload: High iron levels in the body can worsen the condition.
Estrogen use: Hormone therapy or birth control pills can trigger symptoms.
Hepatitis C: Infection with Hepatitis C virus is a known risk factor.

Diagnosis of Familial Porphyria Cutanea Tarda

Diagnosing FPCT involves a combination of clinical evaluation, laboratory tests, and genetic testing.

Clinical evaluation: Doctors assess symptoms and family history.
Blood tests: Elevated levels of porphyrins in the blood can indicate FPCT.
