Hello

I know a family with three CAH children, each affected to a different degree. We have met a child with (heterozygous) CAH despite only one parent being a carrier - this is rare. I understand from various sources, including postings on this message board, that the genetic pathways to CAH are complex, and am finding out that genetics is not the precise science that I assumed it to be. Even if the genetic type (genotype) of CAH is the same, the expression of the disorder (phenotype) can vary - i.e. the symptoms and their severity may differ.

Having said all that, if one child is a salt loser, the other siblings will usually follow. If you are anxious, I would take Lynn T's excellent advice and contact a geneticist with CAH experience.
