    ### Instruction:
    How to diagnose EEC syndrome ?
    ### Response:
    Is genetic testing available for EEC syndrome? It is estimated that greater than 90% of cases of EEC syndrome are caused by mutations in the TP63 gene. The remainder are suspected to be caused by different mutations in a region on chromosome 7. Genetic testing is available to detect both mutations in the TP63 gene and in the implicated region on chromosome 7.
