I get a letter today from the South West Thames Regional Genetics Service about the DDD study. They are writing to tell me that the result of the array study undertaken on B has not so far identified the cause of their developmental difficulties. This is just a preliminary result and further research is activity continuing. Further research will include gene sequencing using the very latest technology that looks across all of the genes. A dedicated team of researchers will keep looking for a genetic diagnosis to explain B's difficulties until October 2015.
They are having considerable success in finding diagnosis for children in whom standard tests have been unsuccessful.
I'm used to hearing no news by now. I've become a little bit hard to it.
