This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. Dr. Hall's research project is to determine the prevalence of fragile X gene mutations in subjects with tremor, ataxia, and/or parkinsonism. Dr. Hall will recruit subjects from her clinics with the three phenotypes and gene testing. The primary outcomes to be measured are the prevalence of gene mutations in the three groups combined and each subgroup. The age of onset, age of diagnosis of neurological signs, and correlations the gene mutation are also outcomes to be measured. This study is important because it may elucidate the etiology of genetic risk factors and result in improved diagnosis and treatment of individuals with illnesses that represent an important public health problem.
