Our youngest daughter has a brain issue that is currently undiagnosed but thought to be a form of leukodystrophy :( I was considering sending copies of reports to Dr Van derr Knapp who discovered 1 type called MLC1 to see if the progression fits the subtypes. It was what the hospital thought she had but a recent mri suggeats maybe not. So far my daughter is a puzzle and it's been 2 years of questions and no answers.
