I just became aware of this from May 2022, so posting the link below for anyone who may be interested: Largest worldwide Tourette syndrome genetics and neuroimaging study also promises insight into related disorders

Hello to all of the incredible parents and caregivers on this forum. I am new here and found this forum through extensive google searches, which always brought me back here and to several of you who have posted extremely helpful information. I cannot than you enough for sharing your stories. My 5.5 YO son has TS, vocal and motor tics for a year. We have followed similar diets (GF/DF/Nut Free) to many of you here and he also has severe tree nut allergies with anaphylaxis, which seems to be a common thread with TS kids (allergies/OCD/ADHD). We've been on a quest for the past year to find the right cocktail of supplements + diet to help jumpstart his gut biome to function more efficiently. We have a Neurologist, a Pediatrician and the most helpful, a Naturopath who has been with us every step of the way. The non-western path is certainly the one for us, and we've recently noticed a few changes with the introduction of PharmaGaba supplements (2 chewable per day) which have significantly reduced the motor and verbal tics. He's only been on this supplement two days and I notice a difference. Wishful thinking? Or a strong connection? There is a Mt Sinai clinical trial looking at GABA's role in TS with Dr. Vilma Gabbay which many believe to be greatly reduced, up to 50% in TS children. We just sent in our 23andme genetic test for our son, which I'm hoping will also lead us down a more focused path. Not as easy to get a kid to spit in a tube as I would have thought, but we collected enough to process. So much new research out there about the role of GABA and Histamines in TS - sometimes overwhelming. In some cases, kids are not producing enough Histamine and in others, and over-production of histamine and it's not going to the "right" places which from what I can gather is why DAO can be helpful. We see a lot of allergies, food allergies, environmental allergies in our son. I'm convinced my son is allergic to carpet backing and any plastic products that off-gas. Looking at chlorine and pools as another possible trigger, as he has swim class weekly (inside) which we're worried is compounding his symptoms. Anyone else see major environmental effects on triggers tics - specifically plastics or chlorine? He had a NutraEval test where his MTBE levels were extremely high, which was why we started to look at the carpeting and carpet backing in his room and in the house. My main reason for posting today is about genetic testing. Has genetic testing helped to guide your treatment decisions for how you supplement and/or approach detox, chelation or natural and herbal healing for your TS kids? If so - which genetic mutations or markers were the most common or important markers in TS and how did this impact your treatment path? We get our results back in a few weeks so plenty of time to mine for more information. I'm so eternally grateful to have found this forum. We are warriors, super sleuths, CSI investigators trying to solve this neurological mystery to make life a bit easier for our children and loved ones. I am sending you all a gigantic hug from cyberspace. Your words and wisdom have helped me get through many rough patches. Thank you! Erin

National Institute of Allergy and Infections Disease have published a new study: http://www.mentalfloss.com/article/87506/one-gene-mutation-links-three-mysterious-debilitating-diseases

Just got one of my DS's 23andMe results. Any suggestions on the best site for the most helpful interpretation of the raw data?

I was just wondering, other than MTHFR, what the most common genetic issues found among PANDAS children have been? Any data or insights appreciated. Thanks! Our story: We suspect ds3 does have PANDAS and are doing the testing, but know from past experience that he has a horrible reaction to extended antibiotic use - last time we did 5-6 rounds for ear infections he was regressing and I thought he would be dx with autism. He recovered, for the most part, once abx were stopped. The worst is Augmentin. Anyway, we've had an organic acids test done that had some mildly funky results but nothing that pointed to one of the very common metabolic disorders. Despite this, however, I strongly suspect there is *something* going on with him genetically/metabolically that really has a drastic effect on his health at times and has let to his mild speech delay and sensory issues.
