Trial of Minocycline to Treat Children With Fragile X Syndrome

Fragile X Syndrome

This is a single center study at the UC Davis MIND Institute in patients age 3.5-16 years of age with fragile X syndrome (FXS), funded by a National Fragile X Foundation Grant. It is a controlled trial of minocycline, an antibiotic commonly used in children for infection or for treatment of neurodegenerative disorders. We are investigating its use in FXS because it lowers matrix metalloproteinase 9 (MMP9) levels, which are high in FXS, and it also strengthens brain connections in the animal models of FXS. We hypothesize that minocycline will likely be helpful for language, behavior and/or cognition in fragile X patients.

Fragile X Syndrome

Fragile X syndrome (FXS) presents alterations in synaptic plasticity that produce intellectual disability. can produce improvement. Estrogens (targeting Estrogen Receptors beta (ER-β) can act as neuroprotective agents, promoting synaptic plasticity and neurite outgrowth, and health benefits derived from flavonoids, as the flavonol epigallocatechin gallate (EGCG), phytoestrogens of natural origin are partially explained by their interaction with membrane ER. Selective ER-β flavonoids are thus good candidates for their therapeutic evaluation in intellectual disabilities. EGCG also targets central intracellular transduction signals altered in FXS and improves memory recognition in a FXS animal model(adenosine triphosphate (ATP)-inhibitor of phosphatidylinositol 3-kinase (PI3K)and mammalian target of rapamycin (mTOR) and extracellular signal-regulated kinase (ERK1/2). This study targets the synaptic plasticity alterations that underlie the learning and memory impairment but also the computational disability in FXS. The hypothesis is that EGCG can act by favoring the physiological processes involved in cognition.

NIPD on cffDNA for Triplet Repeat Diseases

Myotonic Dystrophy 1Huntington Disease1 more

The purprose of this study is to develop and validate an analytical NIPD test for triplet repeat disesases by NGS analysis from maternal blood, searching for the familial mutation in families at risk of having one of the following triplet repeat diseases: Huntington's disease, Myotonic dystrophy, Fragile X syndrome.. A comparison of two 3rd generation long fragment DNA sequencing techniques will be performed. These methods are based of the phasing techniques of parental haplotypes without the proband.

Neuroimaging GABA Physiology in Fragile X Syndrome

Fragile X Syndrome (FXS)Idiopathic Intellectual Developmental Disorder (IDD)

The investigators wish to compare the brain distribution of GABA(A) receptors and GABA levels in young adult males with Fragile X Syndrome compared to idiopathic intellectual developmental disorder. The radiopharmaceutical [18F]flumazenil has been used to study GABA(A) receptor distribution in other genetic syndromes with autistic features; however, despite overwhelming evidence supporting the importance of the GABAergic system in FXS, no clinical investigation of this system in human FXS has been reported in the literature. Therefore, this study will provide the first in vivo comprehensive examination of the GABAergic system in FXS using hybrid positron emission tomography/ magnetic resonance imaging (PET/MRI).

Decisional Capacity and Informed Consent in Fragile X Syndrome

Fragile X Syndrome (FXS)

The Decisional Capacity and Informed Consent in Fragile X Syndrome (FXS) project is for the Eunice Kennedy Shriver National Institute of Child Health & Human Development, 1R01HD071987-01A1, and will provide the first comprehensive description of decisional capacity of individuals with FXS; identify individual, family, and experiential factors associated with variability in decisional capacity; determine the validity of caregiver and expert ratings; and develop evidence-based guidelines for categorizing decisional capacity of individuals with FXS. The researchers will develop a methodologically rigorous and conceptually grounded decision aid using digital technology to enhance participation of individuals with FXS in the consent process.
