The gene coverage data provided by GeneDx represent an estimate based on previous results, but the specific sequencing coverage data for the genes selected may vary from individual to individual, and cannot be predicted exactly. Changes to an approved gene list can only be made by contacting GeneDx directly at 888-729-1206 and asking to speak with a member of our Whole Exome Sequencing Laboratory.
