I’m interested in learning if there’s a relationship between Hirschsprung’s Disease and Waardenburg Syndrome. I was born with Hirschsprung’s Disease. Is it possible it is a symptom of Waardenburg? It appears to me I may have fairly uncommon traits one could attribute to Waardenburg – the dual colored iris and wide nose bridge. There’s also a history of hearing loss in my family – that’s the issue; am I susceptible to hearing loss too? Any and all thoughts are appreciated.
