Research published in December 2016 provides a bit more information about seizure disorders in MECP2 duplication syndrome, particularly as they compare to seizure disorders in Rett syndrome. In general, this is a great piece of research as it describes the course of seizure disorders in Rett syndrome over a period of years. It emerged from the earlier natural history study. Unfortunately from the the perspective of MECP2 duplication syndrome, this publication is a bit disappointing, not because of any weakness in the sturdy or the reporting, but merely because the number of participants with MECP2 duplication and the number of observations in the study was relatively small, which only permitted a very limited picture of this group. If there is a lesson for the MECP2 duplication syndrome study to be learned from this study, it may be the importance of participation in the current natural history study in order for researchers to be able to glean useful information.
Nevertheless this study did briefly report some general observations relevant to MECP2 duplication syndrome:
The following is a message from Dr. Sarika Peters at Vanderbilt University:
We at Vanderbilt University Medical Center are conducting a study of the clinical, immune, and stress markers of disease progression in MECP2 Duplication Syndrome. This study is essential for us in order to establish biomarkers of disease progression, as well as potential clinical endpoints for treatment trials.
Both boys and girls are being included in this study. At this time, we are including children between the ages of 3-18 years. We will be asking you to gather blood and saliva samples from your child, and then will be asking some questions related to their overall functioning, regression, seizures, and illnesses. We will follow-up with you once per year for a total of three years.
Although this study does not require an in person visit, if your child has participated in the natural history study, we do request your permission to have access to their clinical information.
At this time, I unfortunately do not have funds to pay for international shipments of samples.

Researchers at Harvard University are suggesting a new theory of autism. They are raising the possibility that atypical neurological responses to touch can play an important role in developing symptoms of autism, and suggesting that abnormal levels of MeCP2 levels in cells that respond to touch can be critical to the development of symptoms of autism.
Experiments with a number of types of genetically engineered laboratory mice, they found autistic-like behavior developed in those without MECP2 activity in touch cells, but not if normal activity was present in touch cells but not in other cells in the body. There are a number of cautions in interpreting this finding and the associated theory, but there are also a number of general observations that make this theory enticing. Continue reading
This is a reminder about the upcoming conference on MECP2 related disorders in June. This event is really two conferences in one: (1) A family conference for those whose family members are affected by Rett syndrome, MECP2 duplication syndrome, FOXG1 syndrome, CDKL5 disorder, or other MECP2 related syndromes., and (2) a concurrent professional and research symposium on the same disorders. The conference will take place at the Eaglewood Resort in Illinois, June 22-24, 2016.
A recent study looks at the effects of the MeCP2 protein levels on adult brains. Although this study looked at blocking MeCP2 [similar to Rett syndrome and the opposite of MECP2 duplication syndrome], the fact that it showed different kinds of responses depending on the developmental maturity of the lab mice, suggests that the most critical role of the MeCP2 protein may be in the function of the adult brain.
This finding is consistent with Continue reading
Several new studies provide encouraging results about the use of cannabidiol (CBD) oil to treat seizure disorders that are not controlled by other medications. Research also, however, points toward important cautions.
Already in 2016,at least nine studies have been published on CBD and seizures. Two 2016 studies, one from Israel (Tzadok et al.,, 2016) and one the United States (Devinsky et al., 2016) are generally reporting particularly encouraging results. This is not to say the others are negative, just less relevant. The two discussed here are important because they include some results Continue reading
In my last post, I listed a bunch of conditions that had been linked to MECP2 levels in one way or another and suggested “the big picture” about the many roles of MeCP2 may turn out to useful to understanding the best approaches to MECP2 Duplication. After posting it, I came across another paper, “MeCP2-Related Diseases and Animal Models” in the journal Diseases. I thought I should add this supplementary post for a few of reasons. First, this paper provides a very nice summary. Second, it adds a several other conditions to the list that covered in my last post, including rheumatoid arthritis, Huntington disease, and more varieties of cancer. Finally, it is a nice paper medically, and scientifically written but clear enough for a wider audience and it is available to the general public at no cost.
It is very early to speculate, but it is possible that finding a viable method of managing MeCP2 levels may become an important quest, not only for researchers looking for a way to help not only those with MECP2 duplication syndrome (a rare disorder), but for those searching for better ways to treat much more common disorders such as cancer and arthritis. This could massively increase interest and funding for MECP2-related research.

OPINION: This week Nature published a very interesting and possibly groundbreaking study on schizophrenia. It doesn’t mention MECP2 but it does talk about the role of the pruning process in the brain. The way our brains develop is by creating a bunch of new connections and then trimming away the ones that are not needed or helpful. The article suggests that schizophrenia develops when the pruning process goes too far in some parts of the brain. This is also consistent in some earlier reports that did suggest that certain defects in MECP2 were implicated in early onset schizophrenia.
Too much or too little MeCP2 activity has also been connected to a number of other conditions, such as Continue reading
This STV news story with Jenny and Blake McMillan provides a personal perspective on the recent Nature publication of a groundbreaking study showing that MECP2 Duplication Syndrome can be reversed.
