Early Onset of Fragile X Associated Tremor and Ataxia Syndrome: A Case Report from Iran
نویسندگان
چکیده مقاله:
Background: Different alleles of Fragile X Mental Retardation1 (FMR1) gene with separate molecular etiologies cause Fragile X Syndrome (FXS) and Fragile X-associated Tremor and Ataxia Syndrome (FXTAS). Premutation alleles with 55 to 200 repeats in the FMR1 gene lead to FXTAS. It is carried by 1 in 209 women and 1 in 430 men. FXTAS commonly appears in 50- to 70-year-old adults. Case Presentation: An 11 months old boy was referred to the hospital due to clinical presentations of productive cough seizure, mental disability, and ataxia. Magnetic Resonance Imaging (MRI), Electroencephalography (EEG), hematology, biochemistry, hormone, and genetic tests were done. Triplet repeat PCR (TP PCR) showed 99 CGG repeats as permutation alleles. Conclusion: In this study, the authors reported the early onset of FXTAS in an 11 months old boy for the first time.

Fragile X-associated tremor/ataxia syndrome.
Fragile X-associated tremor/ataxia syndrome (FXTAS) is a hereditary neurodegenerative disorder caused by a mutation on the X chromosome. The major signs and symptoms are tremor, ataxia and parkinsonism. Up to one in 2 000 persons over 50 years of age will develop the syndrome. There is reason to believe that too few individuals in Norway undergo testing for this condition.

Carriers of fragile X mental retardation 1 (FMR1) premutation alleles (55 to 200 CGG repeats) are generally spared the more serious neurodevelopmental problems associated with the full-mutation carriers (>200 repeats) of fragile X syndrome. However, some adult male premutation carriers (55-200 repeats) develop a neurological syndrome involving intention tremor, ataxia, dementia, parkinsonism, a...

Fragile X-associated tremor/ataxia syndrome (FXTAS) is an adult-onset neurodegenerative disorder clinically characterized by intention tremor and gait ataxia, in addition to other conditions including hypothyroidism, autonomic dysfunction, hypertension, peripheral neuropathy, and cognitive decline. FXTAS affects some males (approximately 40%) and in less degree female premutation carriers (8-16...

FXTAS (Fragile X-associated tremor and ataxia syndrome) is a late- onset neurodegenerative disorder affecting mainly men, over 50 years of age, who are carriers of the FMR1 gene premutation. The full mutation of this gene causes the fragile X syndrome (FXS), the most common cause of inherited mental retardation. Individuals affected by FXTAS generally present intention tremor and gait ataxia th...

We present the first case report of fragile X-associated tremor ataxia syndrome (FXTAS) in the Republic of Korea. A 75-year-old male developed progressive gait ataxia, parkinsonism, and a mood disorder. Magnetic resonance imaging revealed T2 high signal intensity within the middle cerebellar peduncles. Analysis of the fragile X mental retardation 1 gene revealed a CGG trinucleotide repeat numbe...

Fragile X-associated tremor/ataxia syndrome (FXTAS) is an adult-onset neurodegenerative disorder that affects carriers, principally males, of premutation alleles (55-200 CGG repeats) of the fragile X mental retardation 1 (FMR1) gene. Clinical features of FXTAS include progressive intention tremor and gait ataxia, accompanied by characteristic white matter abnormalities on MRI. The neuropatholog...
