James Manlick is going to homecoming this year and he simply can’t contain his excitement. A huge smile lights up his face as he talks about the dance.

Autism spectrum disorder (ASD) and fragile X syndrome (FXS) are neurodevelopmental disorders with overlapping pragmatic language impairments. Prior work suggests pragmatic language differences may run in families. This study examined specific pragmatic difficulties (i.e., linguistic mazes and perseverations) in boys (9–18 years) with idiopathic ASD (n = 26) and FXS+ASD (n = 29), and relationships with maternal maze use.

Fragile X syndrome (FXS), the most prevalent inherited cause of intellectual disability, remains under-diagnosed in the general population. Clinical studies have shown that individuals with FXS have a complex health profile leading to unique clinical needs. However, the full impact of this X-linked disorder on the health of affected individuals is unclear and the prevalence of co-occurring conditions is unknown.

Improved technique illuminates fragile X protein
Researchers at the Waisman Center made a significant step in understanding the function of a specific protein, FMR1, whose absence causes fragile X syndrome, or FXS. Waisman investigators Xinyu Zhao, PhD, and Anita Bhattacharyya, PhD, with research associate Meng Li, published their paper “Identification of FMR1-regulated molecular networks in human neurodevelopment” in the March issue of the journal Genome Research.

Fragile X syndrome results from a loss of the RNA-binding protein fragile X mental retardation protein (FMRP). How FMRP regulates neuronal development and function remains unclear. Here we show that FMRP-deficient immature neurons exhibit impaired dendritic maturation, altered expression of mitochondrial genes, fragmented mitochondria, impaired mitochondrial function, and increased oxidative stress.

This study investigated the production of demonstratives (e.g., this, that, these) and personal pronouns in school-age boys with idiopathic autism spectrum disorder (ASD) and school-age boys with fragile X syndrome (FXS) with a co-diagnosis of ASD (FXS+ASD).
Cell component breakdown suggests possible treatment for multiple neural disorders
UW-Madison research published today (Feb. 11, 2019) reveals how one mutation causes fragile X, the most common inherited intellectual disability. “Fragile X syndrome has been studied as a model of intellectual disability because in theory it’s comparatively simple,” says senior author Xinyu Zhao, a professor of neuroscience in the Waisman Center at the University of Wisconsin–Madison.
