will having myotonic dystrophy affect my aspirations to be a dentist

Myotonic dystrophy runs in my family. My father has it and one of my 2 brothers has it. I am interested in pursuing dentistry however i worry that i may develop the disease (which would obviously affect my ability to work as a dentist). What do you guys think i should do? getting a genetic test may affect my insurance, and even if it said i did carry the gene, there is a chance it wouldn't be too severe
