Just in the last couple weeks, I began wondering that same question, about LOCAH, CAH or  parents/carriers of CAH.    How old is your LOCAH child?  My CAH daughter is 6 and has never had her cholesterol checked yet, but could ask the endo about this.  Cholesterol is used in the production of hormones in the endocrine pathway/adrenals, and since CAH people don't produce these hormones normally, is cholesterol going unused?  If so, what happens to that unused cholesterol?  My 2 siblings (non CAH, but possibly carriers) are thin and we all have high cholesterol (mine first found 240 at age 21, and 239 at age 40 2 weeks ago, 2 siblings have that range too).  None of us siblings understand our cholesterol being so high.  Both our parent's died from heart attacks at early ages (57 and 71, 20 years ago).  Our father was 45 when had his first heart attack, and had high cholesterol then (also the year his first child was born).   So since birth, we were all raised on low-fat type diets because of how things had to be cooked for our father and the foods he couldn't eat, parent's were also proponents of raw veggies and fruits for snacks (parent's anciently old, dad was 60 with his only children aged 10-15, they didn't have to follow modern yummy junk-food rules they thought! - LOL).  Since parent's both died before my CAH daughters were born, we can't test our parent's to find out who was carrying the CAH gene, but when we look at our parent's med history's, they both seem to exhibit health problems that could be adrenal/endocrine matters.  Currently, I'm having symptoms that resemble primary aldosteronism or 11-beta CAH (daughter has 21-hydroxylase, SW), and still undergoing tests, which last week the doctor said the next step may be a CAT scan or MRI of adrenals to check for hyperplasia.
