My husband and I both had the DNA testing to find out which CAH mutation we carry.  His they found right away, mine they finally just found (after @ 4 months of waiting)!!!  The mutation I carry they have never seen before!?  Does this happen alot?  The lab also recommended that we have our 9 month old SWCAH son tested.  I just don’t see how this is necessary.  I would like to avoid any extra blood draws.  We wanted to find out which mutations we carry for the purpose of any future pregnancy.  Does it make sense to test my son to for this purpose? 

Any thoughts appreciated

Thanks
