International Niemann–Pick Disease Alliance

About Us

Who are we?

The International Niemann Pick Disease Alliance (INPDA) is a global network of non-profit organisations, supporting persons affected by Niemann Pick Diseases (NPD).  The alliance was formed in 2009 to provide a forum for patient groups and professionals working in the field of NPD.

In the 1990s, when a person was diagnosed with NPD they were told they would never meet anyone else affected, as the conditions are so rare. But people directly impacted by the disease – patients themselves, their family members and friends – began setting up support groups, connecting families and drawing in impassioned and dedicated people to fight their corner, determined that no family diagnosed with NPD should face the future alone.

Today, we have an international network of non-profit groups, supporting hundreds of families, and we continue to grow. By joining together through the INPDA, we give Niemann Pick Diseases a stronger global voice, and progress towards effective treatments for these conditions is accelerated.

Our aims

The INPDA’s overall mission is to relieve sickness and distress amongst families affected by Niemann Pick Diseases worldwide.

We will achieve this by sharing expertise, knowledge and skills across our network, providing mutual support between patient groups, improving information and awareness of NPD, and stimulating research.

Our network enables connections, bringing together people who can make a difference for this group of devastating rare conditions.

For more information on what we’re doing to achieve these aims, see Our Work.
