PC and pEDDs at World Congress on Rare Skin Diseases 

June 28, 2026

The World Is Paying Attention to PC and pEDDs 

We were so pleased to see Pachyonychia Congenita (PC) and related painful palmoplantar Epidermal Differentiation Disorders (pEDDs) have such a strong presence at the World Congress on Rare Skin Diseases in Versailles, France, July 1–3. 

Professor Edel O’Toole highlighted palmoplantar Epidermal Differentiation Disorders in a major presentation on the opening day of the congress. She also presented a poster on the pediatric features of children with PC on behalf of Dr. Rebecca McCarthy, who was simultaneously presenting the same research at a different conference in England. 

Another PC Project genetics team member, Dr. Stine Bjørn Gram, presented research on AAGAB-pEDD. (To date, our registry has provided a genetic diagnosis for 22 people with AAGAB-pEDD.) 

It was also exciting to see our friends at BioMendics, Karen McQuire and Aleesha McCormick, share their company’s development pipeline, which includes a potential therapy for pEDDs such as PC. 

Seeing PC and pEDDs represented through scientific presentations, research posters, genetics, and industry development at a global congress is a reminder of how far our community has come. What began as a small patient organization is now helping shape research and future treatments around the world.
