My 18 year old daughter just had a dermatology check up (dad has melanoma). They called to discuss the fact she has 10 cafe au lait spots on her legs and back. Some of these spots are rather large. She was premature (5 weeks early) with a collaspsed lung, pneumonia, anemia. She was in intensive care for 8 days, she weighed 7 lbs, 2 oz at birth, 20 inches. She is now 5' 7", 122 lbs. very active in sports. She has VSD (very small), mild ADD, wears contacts.
We have just finished an extensive series of eye exams, we go in 2 days for results. The next step they are recommending is genetic testing. Does she definitely have a disease because she has these spots? What does the testing involve?
