Psoriasis and Inheritance: Will My Child Inherit Psoriasis?

A Parent’s Worry

When Diana was diagnosed with psoriasis in her early 30s, she wasn’t just thinking about her own skin. She kept wondering: Will my child get this too? Her daughter was just six years old, and every time she saw a rash or itchy spot, the fear crept in.

If you’ve asked yourself the same question, you’re not alone. Many parents living with psoriasis worry about whether their child will inherit it. The answer isn’t black and white but understanding the science behind it can offer both insight and peace of mind.

Is Psoriasis Hereditary?

Yes, psoriasis has a genetic component, which means it can run in families. But having a family history doesn’t guarantee that a child will develop it.

Psoriasis is considered a multifactorial condition, which means it is influenced by a combination of:

• Genetics (inherited from parents)

• Environmental triggers (such as stress, infections, or injuries)

• Immune system function

So, while genetics play a role, they are only part of the story.

What Are the Chances My Child Will Get Psoriasis?

Here’s what research shows about hereditary risk:

• If one parent has psoriasis, the child has about a 10% to 20% chance of developing it.

• If both parents have psoriasis, the risk increases to 40% to 60%.

• In families with no known history, the risk is relatively low—around 1% to 3%.

These statistics are supported by the National Psoriasis Foundation and peer-reviewed research, including studies like Nestle et al., 2009 (Nature) and Nair et al., 2006 (American Journal of Human Genetics).

These are averages. Some children with two parents who have psoriasis never develop it, while others may develop symptoms early in life.

Genetics may influence whether a person is susceptible, but when or if symptoms appear is often influenced by other factors.

What Genes Are Involved?

Researchers have identified more than 60 genetic markers associated with psoriasis. One of the most studied is HLA-Cw6, which is especially common in people with early-onset plaque psoriasis.

These genes are thought to affect:

• Immune system regulation

• Skin cell production speed

• Inflammatory responses

That said, no single gene causes psoriasis. It’s the interaction between genes and the environment that leads to the condition.

What Triggers Psoriasis in Genetically Prone Individuals?

Even if your child carries the genes associated with psoriasis, they might never develop it. Certain triggers can activate psoriasis in those who are predisposed:

• Stress (emotional or physical)

• Skin injuries (scratches, burns, bug bites)

• Infections (such as strep throat)

• Certain medications (like beta-blockers or antimalarials)

• Cold, dry weather

• Obesity or other inflammatory conditions

Helping your child develop healthy habits and manage these triggers can reduce the chance of a flare, even if they do develop psoriasis.

Can I Prevent My Child From Developing Psoriasis?

There is no guaranteed way to prevent psoriasis, even if you know your child may be at risk. But there are ways to support their health and potentially reduce the likelihood or severity:

• Promote good skincare habits early

• Encourage stress management through calming activities and open communication

• Feed an anti-inflammatory diet (fruits, vegetables, omega-3s)

• Limit exposure to harsh soaps or chemicals

• Watch for early signs like persistent rashes or flaky patches and consult a dermatologist if needed

The earlier psoriasis is caught, the easier it may be to manage.

Talking to Your Child and Easing the “What If”

If your child does develop psoriasis, what matters most is your response.

Here's how to support them:

• Be honest but reassuring: Explain that psoriasis isn’t contagious and can be managed.

• Avoid shame or blame: This isn’t their fault—or yours.

• Focus on confidence: Support self-esteem, especially during tough phases like puberty.

• Stay informed: Knowledge helps both you and your child make better decisions about care and treatment.

You can also share resources or communities that help normalize psoriasis and empower young people.

Final Thoughts: You’re Not Powerless

Diana eventually found comfort in learning the facts. She couldn’t guarantee that her daughter would avoid psoriasis, but she could be prepared. That meant having open conversations, building healthy habits, and knowing when to call in the doctor.

Having psoriasis doesn’t mean your child will have it too—and if they do, it doesn’t have to define them. Today, more treatments, tools, and resources are available than ever before.
