From Beast Games Champ to Rare Disease Warrior: Jeff Allen’s 365-Mile Ruck for His Son’s Creatine Transporter Deficiency

May 15, 2025·33 min·2 clips

Jeff Allen says rare-disease dads may need to move from fixing their children’s problems to connecting with them.

1. Once Upon A Gene examines Jeffrey Allen’s advocacy for his son Lucas, who lives with creatine transporter deficiency. 2. Host Effie Parks interviews Allen, a father of two whose public advocacy grew from raising Lucas and seeking support for rare-disease families. 3. The episode asks how a parent can turn a child’s rare diagnosis into awareness, connection, and research momentum. 4. Allen explains that creatine transporter deficiency prevents creatine from reaching Lucas’s brain and muscles effectively. 5. Lucas is seven, has limited understandable speech, developmental challenges, and hypotonia, while Allen says three out of five children with the condition are epileptic. 6. Allen says his older son Jack brought sobriety into his life, while Lucas brought faith and a different understanding of hardship. 7. Allen describes rucking 365 miles from the Nevada border to the California coast to represent the 365 days Lucas carries CTD. 8. Before the California ruck, Allen’s longest ruck had been 15 miles, and he says the challenge changed his view of personal and developmental limitations. 9. Allen recounts meeting Jeremy, contestant number 991 from Beast Games, who offered documentary filmmaking help after hearing Lucas’s story. 10. Allen says the Ruck for Rare route moved through Death Valley, Panamint Valley, Kern Valley, and Southern California orchards. 11. A donation that removed weight from Allen’s back helped him climb above Panamint Valley and notice landscapes he would not have experienced from a car. 12. Allen says seven or eight friends joined him for at least one day of the ruck, turning physical effort into shared support. 13. Terry Jo Bichelle’s 2021 Association for Creatine Deficiencies symposium advice encouraged Allen to seek a platform through a recognizable public figure. 14. Allen applied to Beast Games in early 2024 because Mr. Beast’s 370 million subscribers could expose CTD to a much larger audience. 15. Allen says Beast Games aired in more than 140 countries and allowed him to discuss Lucas after reaching the top 10. 16. Allen describes researchers contacting him about bypassing the SLC6A8 gene and exploring protein modification for creatine transport deficiency. 17. Allen says fewer than 400 CTD children are diagnosed worldwide, while he believes the condition may be underdiagnosed by a factor of 100. 18. The interview includes Allen’s advice that rare-disease fathers should move from fixing to connecting, build relationships, and let themselves be supported. 19. Rare-disease parents, especially fathers seeking practical solidarity. 20. Listeners uninterested in caregiving, advocacy, or genetic disorders may skip.
