Unraveling Fragile X syndrome

نویسنده

چکیده

Imagine a ten-year-old boy with ninety pounds of raw, compressed energy. He has a particular attachment to his Playmobil trucks, rarely sharing his prized possessions with even his older brother. His long face, pronounced forehead, and goofy ears make him unique but it is his personality that is more striking. At the age of ten, he should be zooming around on his bike with his neighborhood pals or reading childhood classics like James and the Giant Peach with his fifth grade classmates. However, he lacks the balance to ride a two-wheeler and he can’t read, or speak, very well. He avoids eye contact with his parents and teachers and most of the time, prefers to be alone.

Early Onset of Fragile X Associated Tremor and Ataxia Syndrome: A Case Report from Iran

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 Presentatio...

Objective: Fragile X syndrome is the second etiology for inherited mental retardation. It may concomitant with other psychiatric disorders. Intellectual disability (ID) is a state of functioning that typically begins in childhood and is characterized by limitations in intelligence and adaptive skills. We intend to introduce a male young patient with Fragile X syndrome and Obsessive-Compulsive d...

Molecular Mechanisms Regulating the Defects in Fragile X Syndrome Neurons Derived from Human Pluripotent Stem Cells

Fragile X syndrome (FXS) is caused by the absence of the fragile X mental retardation protein (FMRP). We have previously generated FXS-induced pluripotent stem cells (iPSCs) from patients' fibroblasts. In this study, we aimed at unraveling the molecular phenotype of the disease. Our data revealed aberrant regulation of neural differentiation and axon guidance genes in FXS-derived neurons, which...

سندرم ایکس شکننده و گزارش 3 مورد (بررسی سیتوژنیک و ملکولی)

 ABSTRACT The fragile X syndrome is the most frequent cause of inherited mental retardation. The fragile site is on the long arm of X chromosome in X q27.3 region. Incidence of syndrome is 1 in 2000 in males and 1 in 2500 in females. This fragile site is visible only with using of special cultural technices. Since females have two X chromosomes, this signs apear less than males. The females who...

Cellular and synaptic network defects in autism.

Many candidate genes are now thought to confer susceptibility to autism spectrum disorders (ASDs). Here we review four interrelated complexes, each composed of multiple families of genes that functionally coalesce on common cellular pathways. We illustrate a common thread in the organization of glutamatergic synapses and suggest a link between genes involved in Tuberous Sclerosis Complex, Fragi...
