Welcome to my SCN2A world

After a hectic period laden with stressful but (thank G-d) joyous events, I can finally refocus on this blog. 

First, to recap.

We now have a pretty firm diagnosis for Haya's symptoms after a 24 year hunt. 

While it is a de novo mutation of the SCN2A gene i.e. not hereditary (yay!), it has been an otherwise distressing discovery. That's because there is simply no effective treatment for it. 

The mutation causes a particularly severe and refractory epilepsy: Epileptic Encephalopathy Early Onset 11. It's sometimes called Early Infantile Epileptic Encephalopathy Type 11, and sometimes EIEE11.

Available anti-epileptic drugs are almost invariably useless, something we'd already concluded on our own after Haya's 24 years of relentless seizing.

Nonetheless, last month we brought Haya to a pediatric neurologist whom our geneticist had recommended highly. (She's booked up for the next year).

At that visit, she assured us she would study Haya's EEG's and her history and would then suggest medication changes as a first step. True, after the years of the med failures we've had, any new ones have no more than a 3% chance of success - but that isn't zero, as the doctor noted. 

So we all agreed it's the wisest first step.

Next, if we find Haya to be in the 97% majority med-wise, this doctor recommended we re-try the Ketogenic Diet. We had Haya on that diet some twenty years ago with minimal success and dropped it after 10 months because of serious, uncontrollable vomiting. 

 
But, as the doctor noted, we had had no professional guidance in calibrating the diet. So giving it a second shot with good medical intervention this time sounds wise.

If that diet fails again, she recommends going with a second VNS implantation. 

That was also a failure back in 2000 and we were bereft of sound medical guidance then too. So while I'm reluctant to subject Haya to surgery but if there's no alternative, we'll try it.

I also set up a Google Alert for the SCN2A gene and Epileptic Encephalopathy Early Onset 11. Not one of the journal articles I've been sent so far are relevant or helpful. Most weren't even about that gene! Are you listening Dr. Google?

Now a request.

The new neurologist, when I asked her, said she has no other patients with this syndrome. Our Haya, I think, may well enjoy the distinction of being the only such person in Israel.

If you know of anybody afflicted with it, please let me know. I will give you my personal details if requested in a blog comment.
