History of PC Project

Pachyonychia Congenita is one of nearly 7,000 rare diseases, 2,000–3,000 of which are rare genetic skin diseases. Over the past 20 years, PC Project with the work of IPCC members, the participation from PC Patients in the IPCRR patient registry and many other supporters, have educated the world about PC and is on the path to developing treatments for PC.

The best place to find the past accomplishments and additional historic information is in the PC News Briefs or Annual Reports. Another option is to read the article “How One Grandmother Fought for Patients of a Rare Disease … When No One Else Would.” The following is an introduction from the author Jack Padovano that was emailed with the article to the PC Community in December 2021.

Below are some brief ‘tidbits’ from the beginning days and achievements of PC Project …


  • Schwartz family sent email requests to institutions and researchers, but received no response. We conducted research to identify rare disease organizations. We also contacted an attorney regarding organization of a charity. Then we saw the article “Saving Ryan” in Reader’s Digest and we set the goal to seek a cure for PC.


  • Schwartz family established inital funding for PC Project in a charitable gift account.


  • First PC Project website posted to internet including grant award information. Citations for a PC bibliography were identified. Filed with the U.S. Internal Revenue Service (IRS) for status as a public charity.
  • Pachyonychia Congenita Fund (PC Fund) aka PC Project was incorporated as a US public charity under 501(c)(3).
  • Bibliography (Published Research Articles) was posted to the website. A brochure for medical professionals and scientists was prepared. We held our first meeting with the Institutional Review Board (IRB) regarding our proposed research registry. PC Project offices were set up and a protected database established for communications and protected data… and we began with 3 PC patients!
  • Initial negotiations to establish a biotech entity to focus on delivery challenges and incorporated TransDerm as a PC biotech firm.


  • Developed concept of three focus areas:
    • (1) Basic and Translational Research
    • (2) Clinical Research and
    • (3) Patient Support
