Renasight™ Genetic Testing

Renasight™ is a genetic test that helps individuals and families understand whether their kidney disease may have a genetic cause. Using a simple blood or saliva sample, Renasight analyzes 397 genes linked to kidney disease, including those associated with polycystic kidney disease (PKD) giving patients clearer answers about their diagnosis and what it may mean for their family.

Why Genetic Testing Matters for Families with PKD

PKD is a condition that can be passed down in families. Knowing this information can help:

  • Provide a more precise diagnosis - Identifying the PKD subtype or the specific gene responsible in a family (such as PKD1 or PKD2) can help your doctor better understand what to expect and guide your treatment plan.

  • A more personalized treatment plan -  Help your healthcare provider choose care that fits you best. This may include available treatments for certain type of cystic kidney disease and see if you qualify for clinical trials.

  • Empowered Family Planning -   Understand the likelihood of passing the condition to future generations, allowing you to make informed reproductive decisions.

  • Identify at-risk family members - Help relatives learn if they may also be at risk so they can consider early screening or monitoring.

For many families, knowledge brings both clarity and control.

Empowering the Next Generation

Because PKD is passed down through families, genetic insights can play an important role in breaking the cycle. Understanding your genetic status may support:

  • Earlier monitoring and proactive care

  • More informed reproductive decision-making

  • Open conversations within families about risk and testing
