Help Protect the Ones You Love: Start Your Free OTC Risk Prescreening

Ornithine transcarbamylase (OTC) deficiency is a rare genetic disorder that affects the body’s ability to remove ammonia, a natural waste product of protein breakdown.

When OTC isn’t working properly, ammonia can build up to dangerous levels, leading to symptoms such as confusion, vomiting, lethargy, seizures, and, in severe cases, coma. OTC deficiency can affect both children and adults—and because symptoms can appear suddenly, it often goes undiagnosed until it becomes life-threatening.

What makes OTC deficiency particularly challenging is that it frequently runs silently in families. Many individuals carry the genetic change without knowing it, passing it down through generations without warning. In some cases, the first sign of risk appears only when a severe event occurs. But it doesn’t have to be this way.

Early Detection Can Save Lives

OTC deficiency is highly treatable when discovered early. With proper medical care, dietary guidance, emergency protocols, and ongoing monitoring, individuals with OTC deficiency can manage the condition safely. The challenge is simply knowing who is at risk before symptoms appear.

That’s where Quoiden comes in.

How Quoiden Makes Screening Accessible

Quoiden was created to help families uncover hidden genetic risk through a simple, private, and compassionate process. We start with a free prescreening questionnaire designed to quickly assess whether OTC deficiency may run in your family. It only takes a few minutes and can be completed from home.

If the prescreening suggests you may be at risk, you may qualify for no-cost at-home genetic testing to check for the OTC gene variant. Testing is quick, secure, and supported by experts. For many families, this process offers clarity, peace of mind, and—if needed—a path to early care.

Why It Matters

OTC deficiency doesn’t have to remain a hidden threat. By combining family history with modern genetics, we can identify risk sooner, support informed decision-making, and help individuals access the medical guidance they need.

Whether you’re concerned about symptoms, exploring your family history, or simply want to understand your genetic health, Quoiden is here to help you take the next step with confidence.
