Prosem Lecture: The FMR1 gene: Genotype-Phenotype Studies
February 1 @ 12:00 pm - 1:00 pm
Presenter: Nell Maltman, Ph.D., Postdoctoral Fellow Waisman Center, UW-Madison
Topic: The FMR1 gene: Genotype-Phenotype Studies
The FMR1 gene is essential for healthy neural development, and variation in the gene impacts a range of physical, cognitive, and language processes. FMR1 expansions (>200 CGG repeats) cause fragile X syndrome, the most common inherited cause of autism and intellectual disability. Smaller expansions, known as the premutation (>55 CGG repeats), can cause premature ovarian failure, a neurodegenerative disorder (FXTAS), and a range of clinical and subclinical differences in language, cognition, and mental health. The premutation expansion occurs in ~1 in 150 females and ~1 in 470 males, so understanding the relationships between genetic and phenotypic expression is vital from a public health perspective. The goal of this presentation is to 1) explore how FMR1-related variation influences cognition and language, and 2) examine how aspects of language (i.e., dysfluencies) predict later clinical symptoms associated with a neurodegenerative disorder. Findings from these studies suggest that FMR1 variation and environmental factors (i.e., stress) influence cognition, and that language fluency may be a potential preclinical marker of FMR1-associated neurodegeneration. Future directio ns and implications are discussed.
