Mission and programs · 2025

Mission

The mission of the Phelan-McDermid Syndrome Foundation is to make today better and the future brighter for everyone living with Phelan-McDermid syndrome - from the moment of diagnosis to the delivery of treatments and cures.

  • CONNECT (Family Support): The Organization (PMSF) connects with families from diagnosis throughout their life journey, providing essential support, knowledge, and skills to navigate the complexities of Phelan Mc-Dermid syndrome. In 2025, PMSF provided 2,400 connections through comprehensive support services, welcoming 300 new families into membership. Key initiatives included supporting 133 newly diagnosed families via the "First 100 Days" program, educating 250 caregivers and professionals through the "Pathways" video series, and facilitating 48 Caregiver Support Group sessions for 250 participants. These programs integrate mental health, social, and emotional well-being, while regional and international gatherings further empower our community to thrive.

    Expenses $192,052

  • CARE (Improving Medical Care): The Organization (PMSF) ensures that individuals with Phelan-McDermid syndrome have access to a robust community of specialists and evidence-based care. We bridge the gap between research and clinical practice by educating professionals, facilitating medical consultation, and expanding our specialized clinical infrastructure. In 2025, we strengthened this ecosystem by establishing our first 11 Phelan-McDermid Syndrome Clinics-including a new multidisciplinary center at Cincinnati Children's Hospital Medical Center-and launched initiatives to grow our Healthcare Provider (HCP) network. Our experts facilitated 22 neuropsychiatric consultation cases, 15 neuropsychiatric referrals, and 50 genetic counseling referrals. Additionally, we served as a primary medical hub, recording over 100,000 views on pmsf.org and overseeing 3,500 downloads of clinical and educational resource documents.

Compensation is as filed in Part VII: reportable pay from this organization and from related organizations, other compensation, and hours per week. The total, marked calculated, is our sum of the three dollar columns, with a blank column counted as $0; the form itself has no total. On a Form 990-EZ the columns are Part IV's instead, and on a Form 990-PF Part VIII's — compensation, contributions to benefit plans, and expense account — and the total sums those.
