Show Your Stripes for Gracelynn 🦓
Gracelynn is the only daughter of one of my assistants at Coker Rehab, Sarina Brown. In honor of Rare Disease Month this February, we are asking our friends, patients, and community to consider making a donation to help their family during a difficult season and to assist with Gracelynn’s ongoing medical expenses. Even a couple of dollars makes a difference — truly. Every bit of support helps lighten the load.
🦓 Meet Our Zebra: Gracelynn 🦓
Over 300 million people worldwide live with a rare disease.
1 in 10 Americans is on a rare medical journey.
72% of rare diseases are genetic.
The zebra ribbon is the symbol of rare disease awareness — and Gracelynn is our zebra.
Looking at her, you’d never guess the daily fight she faces. She’s a sweet girl with an infectious smile who spreads happiness everywhere she goes.
At just 8 days old, a newborn screening revealed a life-changing diagnosis: Profound Biotinidase Deficiency, a rare genetic disorder affecting 1 in 140,000 children. Without treatment, it can cause seizures, brain damage, hearing and vision loss, and other severe complications. Thankfully, daily biotin keeps her safe — but it must be purchased out of pocket because insurance doesn’t cover it.
Gracelynn also lives with:
• PFAPA (periodic fever syndrome)
• Marcus Gunn Jaw Wink syndrome affecting her left eye
• Immune fragility that prevents her from attending regular school or daycare
She requires weekly therapies and care from 8 specialists. Her parents juggle appointments, treatments, and constant medical vigilance — all while navigating serious financial strain after a recent job loss.
Rare Disease Day is February 28. Research for rare diseases is underfunded, and families often walk this road feeling isolated. It doesn’t have to be that way.
We are asking our community to help this incredible family stay afloat during this difficult season. Donations will go directly toward:
✔ medical expenses
✔ housing costs
✔ daily living needs
✔ therapies and treatment
Every contribution — big or small — helps ensure Gracelynn continues receiving the specialized care she needs.
If you can’t donate, please consider sharing her story and helping us in support of rare disease families everywhere.
Thank you for surrounding this family with love. 🦓💛
