In this episode of Rare Connection, I talk with Jillian Kavanagh, a nurse practitioner and parent to Ellie, who was diagnosed with Okur-Chung Neurodevelopmental Syndrome (OCNDS) at age 4. With only about 300 known cases worldwide, OCNDS is an ultra-rare genetic condition caused by variants in the CSNK2A1 gene.

Jillian shares the challenges of Ellie’s early epilepsy diagnosis, the long road to genetic testing, and how life changed after finally receiving answers. As a founding member of the CSNK2A1 Foundation, she is working to bridge the gap between the medical community and the families affected by OCNDS.

💡 What you’ll learn in this episode:

  • What OCNDS is and how it’s diagnosed
  • The struggles parents face navigating rare disease care
  • Why genetic testing is critical — and often out of reach for many families
  • How Jillian uses her professional and personal experience to advocate for change

CrimeLess: Hillbilly Heist

CrimeLess: Hillbilly Heist

It’s 1996 in rural North Carolina, and an oddball crew makes history when they pull off America’s third largest cash heist. But it’s all downhill from there. Join host Johnny Knoxville as he unspools a wild and woolly tale about a group of regular ‘ol folks who risked it all for a chance at a better life. CrimeLess: Hillbilly Heist answers the question: what would you do with 17.3 million dollars? The answer includes diamond rings, mansions, velvet Elvis paintings, plus a run for the border, murder-for-hire-plots, and FBI busts.
