I went to the above URL and it certainly put's a spin on things.

I learned differently and speak from just having learned the simple side of genetics as explained to me 9 years ago in genetic counselling.  There is another theory here I have in that no matter how it is derived, if an individual has symptoms of CAH, they are sufferers really.  Sufferers have physical symptoms as well as passing on the gene and this would make absolute sense here, especially with Kaye because I beleive that the incidences are more likely to occur with a sufferer and a carrier or two sufferers having children arn't they?  Precisely  1 chance in 2 for a sufferer and a carrier when conceiving children.  Then every child a sufferer when two sufferers conceive children together?  Well this is the way I understood it anyhow---ages since I even brushed up on this it is like this:

Two carriers the chances are 25% = 1 in 4 chances for each child conceived.

A carrier and a sufferer it is 50% = 1 in 2 chances for each child conceived.

A carrier and a carrier it is ALL children who inherit the CAH = 100%

We went through this in genetic counselling as my daughter was found to be a carrier and so we wanted to know her chances of meeting and having CAH and my sons should he meet either a carrier or a sufferer just to have the knowledges.  

When I say "sufferer" I realise that this sounds sometimes odd but that is the way it is described in genetic terms. 

Have your parents been included in this testing Kaye?
