I have EHK or the blistering CIE (Im pretty sure that's the right way to say it.). my oldest son (19mo) also has it. my 4 month old doesn't.
I'm not sure what the chances would be but do you know if either of you are carriers or was it a spontaneous mutation? that would give you an idea on your chances of another baby with it.
