Welcome and thank you for following Marley’s CDKL5 awareness page. This page is designed to spread awareness for people who like Marley are living with CDKL5 and the daily struggles, challenges and successes the condition brings to their lives.
Introducing Marley and some information on her life so far. Marley is just over 10 month old. Unfortunately, when she was 3 weeks old, we now know she had her first seizure, this was on Friday, the 23rd of May 2025. After some time of staying in Newcastle RVI Hospital Marley had multiple tests done to confirm weather or not she was having seziures and to try a work out why? A few weeks after being discharged when Marley was 8 weeks old we had the phone call to say that the R14 genetics testing had came back with a positive result, I initially was happy as to me a positive result meant a way to fix and a way to stop our baby from having seizures all the time, this was not quite the case. Marley has a rare neurological condition called CDKL5 deficiency disorder which currently has no cure, is life-threatening, the seizures are very hard to control as they are anti-seizure and anti-epileptic medicine resistant, there is currently no gene therapy made to fix the issue and the condition comes with a lot of health complaints, e.g. she is highly likely to not be able to walk or talk, she will have neurological issues, developmental delays, a lifetime of seizures and she may have visual disturbances and could end up being blind, lots of people with this condition also have gastrointestinal issues that require a feeding tube along with lots more issues… the list of issues feels endless. Gene therapy would be the only cure in the future and at the time of being diagnosed it was looking as though it wouldn’t be available worldwide for another 15 years. She has had multiple seizures a day every day since she was 3 weeks old up until the 19th January 2026 where she started a new anti-epileptic drug, Clobazam along side her sodium valproate and levetiracetam, since then she has now only had 4 seizures in the last 7 weeks which is amazing compared to 3-6 a day every day. We feel extremely thankful and lucky for every seizure free day she gets as we know they are not guaranteed. We have so much more to share about Marley’s life but I thought a semi brief introduction would be a great place to start. For right now we are enjoying seeing our baby girl finally start to hit some developmental milestones and we are staying hopeful for better days ahead and more success to share❤️
