Genes and Dystonia

Advertisements

Following on from yesterday’s Facebook live where we touched briefly on genetic causes of Dystonia, I wanted to delve into this a little more. DYT1 gene is the cause of some cases of early onset Dystonia and seems to be the one people are aware of. However there is a number of other genes that can cause Dystonia. Knowing whether it is a genetic cause is worth investigating as treatment can differ. For example I have the GCH1 gene which is the cause of Dopa Responsive Dystonia. I’ve lived with my symptoms for eight years and only recently found this out. I’m now awaiting to start on the appropriate medication for this particular type of Dystonia.

Taken from http://www.scielo.br/scielo.php?script=sci_arttext&pid=S0004-282X2015000400350#:~:text=DYT6%20dystonia%20has%20an%20autosomal,no%20sex%20differences%20identified9.

Being diagnosed with Dystonia for the majority of people is a long road, and more complicated still if you don’t know the medical history of your parents, grandparents etc. I haven’t had contact with my father for years but I know from my mum that he had hand tremors and was often called shakey. Now this could be caused by anything and that’s important to remember but based on the fact that my hands also spasm and tremor it’s a significant point.

When I was on the initial road chasing for a diagnosis only one doctor recommended genetic testing and this was never followed up on. I then spent years fighting against the label of functional Dystonia, which seemed to being applied purely based on my previous traumas. It became a frequent sticking point, one in which I often pointed out that fighting for treatment and belief was by far more traumatic at the time than issues I’d already worked through with therapists.

It was only after resorting to private genetic testing that we discovered that I had a genetic cause; I’d been blaming it on a horse riding accident for years purely because my neck spasms started shortly afterwards.

So does having a genetic cause change anything? Yes! Some types of Dystonia are far more likely to respond to Deep Brain stimulation, while others respond to specific medications better.

It is important to remember however that not all Dystonia causing genes are known yet. This is one of the reasons family history is so important. I only went digging into my genes after my maxfax surgon mentioned that their appears to be a link between Ehlers-Danlos Syndrome and Dopa Responsive Dystonia.

Other causes can be medication induced (tardive dyskinesia), brain injury, as a symptom of another condition etc. If you have concerns over the root cause of your condition please speak to your neurology team.

What Causes Dystonia?

Currently the exact cause of Dystonia is not known; though a number of problem areas have been linked to the condition. Research has shown that there is a fault with a section of the brain called the basal ganglia. It is only in a small minority of sufferers that the condition has a clear cut cause.

Dystonia can appear on its own, secondary to another medical issue or as a result of medication – this is known as Tardive Dyskinesia. At the current time 80% of children diagnosed with Dystonia have it alongside a primary condition for example Cerebral Palsy. In adults the condition can be caused by a stroke and other neurological issues.

As research is progressing more genes are being found to be related to different forms of the condition. Studies have found that some cases of Generalised Dystonia are hereditary. However even if there is a genetic issue it does not guarantee that you will pass on the condition. It is thought that there is between a thirty to fifty percent chance of a child inheriting Dystonia depending on the mutated gene and type of Dystonia. So far over 20 genes have been identified in relation to Dystonia, with more being found all the time.
