Auditory Dysfunction in Fragile X Syndrome, Role for the Sound Localization Pathway

Auditory Dysfunction in Fragile X Syndrome, Role for the Sound Localization Pathway

FRAXA Research Foundation has renewed Dr. Elizabeth McCullagh’s 2017 FRAXA Fellowship for a second year. Dr. McCullagh and Principal Investigator Dr. Achem Klug are investigating the “cocktail party effect” in Fragile X mice. There is a specific circuit which allows us to discriminate between competing sound sources, helping us focus on a sound source of interest such as with a conversation partner. If clear differences are found in this circuit, they could be used as potential biomarkers for Fragile X clinical trials.

Cellular-Specific Therapeutic Targeting of Inhibitory Circuits in Fragile X Syndrome

Cellular-Specific Therapeutic Targeting of Inhibitory Circuits in Fragile X Syndrome

Studies have shown that the function of inhibitory networks is disturbed in Fragile X. This abnormality is not well understood but appears to be secondary to abnormalities in metabotropic glutamate and endocannabinoid systems. With a $90,000 grant from FRAXA in 2013-2014, Dr. Molly Huntsman’s team examined how these networks interact and how inhibitory deficits can best be remedied.

Neuromotor Outcome Measures for Clinical Trials in Fragile X Syndrome

Neuromotor Outcome Measures for Clinical Trials in Fragile X Syndrome

With a $35,000 grant from FRAXA Research Foundation, Dr. Nicole Tartaglia from the University of Colorado Denver and Tracey Stackhouse aimed to develop neuromotor outcome measures for use in clinical trials in FXS, and to contribute to a deeper understanding of the neuromotor issues involved in FXS. This collaborative project was completed at the two sites of the Colorado Fragile X Clinic: The Children’s Hospital and Developmental FX. Dr. Nicole Tartaglia is the Medical Director of the Fragile X Clinic at The Children’s Hospital of Denver. Tracy Murnan Stackhouse, MA, OTR is the co-founder of the Developmental & Fragile X Resource Centre (Developmental FX), a clinic specializing in Fragile X.

Treatment of a Mouse Model of Fragile X Syndrome with MPEP

Treatment of a Mouse Model of Fragile X Syndrome with MPEP

With a $49,000 grant from FRAXA Research Foundation in 2003, Dr. Linda Crnic at the University of Colorado continued studies of MPEP in Fragile X mice, exploring whether chronic use ameliorates symptoms of Fragile X syndrome without impairing cognitive function.
