Nine years after the tremor onset, he developed symptoms resembling Fragile-X-associated tremor/ataxia syndrome (FXTAS), including exacerbated (increased coarseness and amplitude) tremor in the right arm, ataxic gait, and brain MRI showed lesions in the bilateral middle cerebellar peduncles (MCP). Evidence of premutation in the form of 83 CGG repeats of the Fragile-X-mental retardation 1 (FMR1) gene confirmed the diagnosis of FXTAS. FXTAS causes various neurological symptoms including in some cases tremor resembling essential tremor in the early stages. FMR1 gene premutation should be checked when the patient develops intention tremor, cerebral dysfunction and/or a brain MRI shows MCP lesions.","is_dataset_classified":null,"base_score":2.639057329615259,"endowment":2.639057329615259,"datacite_reuse_total":0,"file_count":0,"downloads":0,"views":0,"has_version_chain":false,"is_dataset":false,"is_oa":false,"pmid":"20558944","pmcid":null,"openalex_id":"https://openalex.org/W1967263015","authors":[],"funders":[],"total_grants":0,"fwci":0.5269,"citation_percentile":0.69458671,"influential_citations":0,"citation_trend":[{"year":2012,"count":1},{"year":2014,"count":1},{"year":2016,"count":2},{"year":2018,"count":2},{"year":2020,"count":1},{"year":2021,"count":3},{"year":2026,"count":1}],"oa_status":"bronze","license":null,"oa_locations":[{"url":"https://www.jstage.jst.go.jp/article/internalmedicine/49/12/49_12_1205/_pdf","host_type":"journal"},{"url":"https://www.jstage.jst.go.jp/article/internalmedicine/49/12/49_12_1205/_pdf","host_type":"publisher"},{"url":"http://www.jstage.jst.go.jp/article/internalmedicine/49/12/49_12_1205/_pdf","host_type":"publisher"},{"url":"https://doi.org/10.2169/internalmedicine.49.3258","host_type":"journal"},{"url":"https://pubmed.ncbi.nlm.nih.gov/20558944","host_type":"repository"}],"fields_of_study":["Genetics and Neurodevelopmental Disorders","Genetic Neurodegenerative Diseases","Mitochondrial Function and Pathology","Aged","Asian People","Ataxia","Fragile X Messenger Ribonucleoprotein 1","Fragile X Syndrome","Humans","Male","Tremor"],"mesh_terms":["Aged","Ataxia","Fragile X Syndrome","Humans","Male","Tremor","Asian People","Fragile X Mental Retardation Protein","Fragile X Messenger Ribonucleoprotein 1"],"keywords":["Intention tremor","Gait Ataxia","Ataxia","FMR1","Medicine","Essential tremor","Ataxic Gait","Fragile X syndrome","Cerebellar ataxia","Gait","Movement disorders","Physical medicine and rehabilitation","Pediatrics","Audiology","Fragile x","Psychiatry","Pathology","Disease","Genetics"],"sdg_mappings":[{"sdg_number":0,"sdg_label":"Good health and well-being"}],"linked_datasets":[],"clinical_trials":[],"software_tools":[],"database_accessions":[],"source":"live","citation_network_status":"fetched"},"created_at":"2026-08-04T00:20:54.136488Z","pmid":null,"pmcid":null,"fwci":null,"citation_percentile":null,"influential_citations":0,"oa_status":null,"license":null,"views":0,"total_file_size_bytes":0,"version_count":0,"fair_f":null,"fair_a":null,"fair_i":null,"fair_r":null,"fair_zscore":null,"fair_rationale":null,"fair_model":null,"fair_agent_version":null,"fair_fulltext_source":null,"fair_has_llm":null,"fair_computed_at":null,"clinical_trials":[],"software_tools":[],"db_accessions":[],"linked_datasets":[],"topics":[]}
