WELCOME TO THE ULTRA RARE COLLECTION II: The Mother of All Art Shows

This is more than an art auction. It’s an alliance for change.
And we’re thrilled you’re here.

The Ultra Rare Collection (URC) is a bold, first-of-its-kind online art auction presented by Project CASK, where creativity meets urgency — and where every creative gesture helps forge a path toward hope for children living with one of the rarest neurological conditions in the world.

Under the theme “The Mother of All Art Shows,” 30 works of art explore motherhood, caregiving, family, and love — the forces that drive us forward when the road is uncharted and the stakes are sky-high.

WHY YOUR BID MATTERS

CASK gene disorders affect fewer than 400 people worldwide. They deny children abilities many take for granted — movement, speech, independence, good health — and they have no treatments or cure. Because of its ultra-rare status, therapeutic development for CASK is often overlooked by industry and underfunded by traditional research pipelines.

That’s where you come in.

Every piece of art purchased through the URC fuels real-world scientific progress. The first URC helped fund the first-ever gene replacement therapy study for CASK and a second small molecule study aiming to treat one of its most devastating features.

Join the Liocorn Pride 🦄 Rare as unicorns. Strong as lions.🦁

Join this collaborative force of artists, advocates, scientists, and families pushing the boundaries of what’s possible for children with CASK.

Place a bid. Share with your network. Help us build a world where every child, no matter how rare, can grow, thrive, and pursue their dreams.

WHO WE ARE

Project CASK is a parent-led, scientifically guided nonprofit with a single, urgent mission: to accelerate research that leads to treatments and ultimately, a cure for CASK gene disorders. Founded in 2023, we are relentless in our belief that ultra-rare does not mean unworthy. We’re here to change the future — one discovery, one collaboration, one piece of art at a time.
