<<Disclaimer: Verify this information before applying it to your situation.>> Can anyone offer a ball park figure for the cost of a CD gene test? Is the process significantly different between that test offered by Dr. Fine and more conventional gene testing? I realize that this will only be helpful in ruling out CD as a cause of problems if the person has no form of the gene. Also, can the gene test determine whether the predisposition comes to you from both parents? Please offer web sites for gene info that you found helpful.
