Re: xxxy syndrome, job syndrome(hyper ige) and hypohidrotic ectodermal dysplasia
Amy, I don't know anyone with these disorders, but I have a hypothesis for you. Since many rare disorders are x-linked (on the x chromosome), your son ended up having 3x the chance of receiving an x-linked disease. Do you know if the other conditions are x-linked or not?
I hope you find some answers
