Auditory Dysfunction in Fragile X Syndrome in a Mouse Model of Fragile X

April 5, 2021

FRAXA-funded studies found Fragile X mice show altered auditory circuit function with delayed startle timing and reduced prepulse inhibition, mirroring human sound sensitivity.

Effects of minocycline on vocal production and auditory processing in a mouse model of Fragile X

June 2, 2013

With FRAXA funding, Dr. Khaleel Razak and Dr. Iryna Ethell explored robust biomarkers relevant to the FXS and the efficacy of minocycline treatment.

GABAergic Inhibitory Function in Fragile X Syndrome

February 1, 2011

Fragile X mice show weakened GABAergic inhibition in key brain regions like the amygdala. Enhancing GABA_A receptor activity reduced hyperactivity and improved inhibition.

Genome-wide Epigenetic Markers in Fragile X

February 5, 2009

With $45,000 in grants from FRAXA Research Foundation over several years, Dr. Miklos Toth of Cornell University studied epigenetics (ie factors other than the gene itself) which can determine symptom severity in Fragile X.

Baclofen: GABA(B) Receptor Supersensitivity and Normalization of Behavioral Abnormalities by Various GABA(B) Agonists Including Baclofen in FMRP Deficient Mice

October 16, 2006

FRAXA’s $110K grant supported Dr. Miklos Toth at Cornell in discovering that baclofen corrects the heightened startle response in Fragile X mice.

Therapeutic Interventions in FMR1 Knockout and Transgenic Mice: Role of the FMR1 Gene

February 13, 2006

With FRAXA’s $229K grant, Baylor researchers showed that Fragile X protein levels in the brain affect activity and anxiety in mice and humans.

Linda Crnic, PhD, at University of Colorado, FRAXA research grant

Treatment of a Mouse Model of Fragile X Syndrome with MPEP

January 1, 2003

A $49K FRAXA grant helped Dr. Linda Crnic’s Colorado team study chronic MPEP use to ease Fragile X symptoms while preserving cognition.

Prepulse Inhibition in Fragile X

June 27, 2001

With $27K from FRAXA, Dr. Alcino Silva studied prepulse inhibition in Fragile X mice and children, linking lab findings to real-world behavior.

Startle Modulation in Males with Fragile X Syndrome

February 27, 2001

FRAXA’s $42,720 grant helped Dr. Elisabeth Dykens uncover startle and PPI effects in Fragile X males. Results were published.
