There is no link that I know of between craniosynostosis and congenital hyperplasia or in Liams case hypopasial.  However, I always find it amazing that two extremely rare conditions would be novile or spontaneous mutations in the same child.  That is why I am interested in research looking into environmental factors but the rarer the condition is the less research is done.   Liam also had epilepsy for the first three years and that was not attributed to his craniosynostosis, but thankfully he grew out of that.  We had a tough time with various epileptic medications because they clouded the issue of CAH by affecting his metabolism in different ways.  Today, everthing has become very routine and to date have had no scares concerning his CAHypoplasia.  However, the fact that he has no adrenal cortex makes the management of the condition relatively straight forward.

I will sign off now.
