The imperative for multigenerational genetic screening: A case report of fragile X-associated tremor/ataxia syndrome (FXTAS)

Due to the highly variable clinical presentation of FXS within families, clinicians should always consider fragile X testing and detailed family history when middle-aged and elderly males exhibit unexplained cognitive impairment or tremors. With the acceleration of aging in society, this case underscores the importance of multigenerational genetic screening for maternal grandparents, particularly males, in FXS families and prioritizing follow-up monitoring.
