based on my experiences, my parents refer me to pediatrics, and confirm it through medical assement which is observe my physical, and run some blood test.. but for best confirmation please refer to clinical genetics..
We were diagnosed by a geneticist. However, a good dermatologist or ortodentisya can also make the diagnosis with a examination practitioner. Existence the test genetico but it is Expensive it is not the Whole Plan of Health covers the cost.
My son is born in 2000 and he was diagnosed HED when he was 9 months old. Pointy teeth, no hair, no sweating. He his now 15 and doing fine with who he is.
He know he is love for who he is, and he is a sweet, loving, caring, gamer guy!
