"Now I Knew Where We Were Going," by Sophie Muir

Sophie spent years fighting for a son no one could diagnose. Then a letter arrived with six letters and a number.

Sophie Muir is the Founder of the Timothy Syndrome Alliance (TSA), a UK charity supporting families affected by CACNA1C-Related Disorders across 44 countries. A former professional turned full-time carer and advocate, she built the organisation from a kitchen table and a letter she was scared to open. She is based in the UK with her husband Nick and their three sons.
