Just found out that dd1 (5) has a defective gene which causes Tuberous Sclerosis. She has other symptoms too - epilepsy (absence seizures - controlled by medication, but this was the catalyst to further tests), patches on her skin and on her brain. In all other aspects of her development she's great - very bright and eager to learn. However, when I asked the genetic doctor if dd might get worse as she gets older, he said he couldn't say as he couldn't predict the future (we live in Holland where people are very forthright!). I'm now worrying that although dd1 is great at the moment, later on things could all go wrong. There are so many variances of the condition and I've looked it up on the net, but can't find anything which discusses any progression of the condition. Does anyone have any experience of TS they might be able to share with me? DH and I now have to be tested to see if either of us has the condition.
