Hi, when we had Casey's gene testing done at GeneDx, it was by a simple blood test. She was negative for TGM1, ALOX12B and ALOXE3.
She finally tested positive for a mutation in the Ichthyin gene.
Mom to Casey born Feb 17/08(?LI/CIE), Sara born Feb 18/06, and Kaitlyn born July 2/03
Casey has been tested positive for a genetic mutation in the ICHTHYIN gene (which is indicative of either LI or CIE)
