Plaque psoriasis is a chronic autoimmune condition characterized by red, scaly patches on the skin. Many patients wonder about its hereditary nature.
Q: Is plaque psoriasis hereditary?
A: Yes, research indicates that there is a hereditary component to plaque psoriasis. Family histories often reveal a higher incidence of the condition among relatives.
Q: What does the science say about the heritability of plaque psoriasis?
A: Various studies show that individuals with a family history of psoriasis are at an increased risk of developing the disease. Genetic studies have identified several loci associated with psoriasis susceptibility.
Genetic Factors
- Studies show that if one parent has psoriasis, the child has a 10-30% chance of developing it.
- If both parents have psoriasis, this risk increases to 50-60%.
- The HLA-Cw6 allele is one of the most strongly associated genetic variants linked to psoriasis.
Statistical Overview
Factor | Percent Risk |
---|---|
One parent affected | 10-30% |
Both parents affected | 50-60% |
No family history | 1-3% |
Environmental Influences
While genetics play a significant role, environmental factors can also trigger or exacerbate the disease. Common triggers include:
- Infections
- Stress
- Skin injuries
- Extensive alcohol consumption
- Smoking
