    Fragile X syndrome is a condition that relates to the mental capacity of an individual. This particular disease is inherited and is the number one contributing factor to mental retardation, aside from Down syndrome. There are a variety of different symptoms attributed to this disease as it is one of the most prevalent medical conditions .   You will often see lists of facts about Fragile X Syndrome being circulated, detailing medicalised information focusing on the challenges that people with the condition may face. However, this doesn’t fully represent Fragile X. In this piece, we celebrate the fact that the challenges associated with living with Fragile.

      What is Fragile X syndrome? Fragile X syndrome is a genetic disorder that affects a person’s development, especially that person’s behavior and ability to learn. In addition, Fragile X can affect: Communication skills Physical appearance Sensitivity to noise, light, or other sensory information Fragile X syndrome is the most common form of inherited intellectual and developmental.   Mutations (changes) in the FMR1 gene cause fragile X syndrome (FXS). The FMR1 gene contains a section of DNA called a CGG triplet repeat, which normally repeats from 5 to around 40 times. In most cases of FXS, this section of DNA is repeated more than times, which "turns off" the FMR1 gene and disrupts the function of the nervous system. In a small portion of cases, other types .

    Fragile X syndrome (FXS) is one of the more common known causes of intellectual disability that can run in families (inherited). FXS is caused by a change in the genetic material in each cell of the body. This change in genetic material makes it hard for cells to produce a protein that is necessary for normal brain development and normal brain. A guide for the newly-diagnosed and those already living with Fragile X.

Fragile X syndrome (FXS) is a genetic disorder. FXS is caused by changes in a gene that scientists called the fragile X mental retardation 1 (FMR1) gene when it was first discovered. The FMR1 gene usually makes a protein called fragile X mental retardation protein (FMRP).

FMRP is needed for normal brain development. Read an overview of CDC’s work on fragile X syndrome. Fragile X Syndrome Fact Sheet pdf icon[PDF – KB] Learn basic facts about fragile X syndrome. Available in English and Spanish.

Fragile X syndrome (also called Fragile X) is the most common inherited form of mental problems (mental retardation).; Fragile X syndrome is caused by changes in a single X chromosome (FMR1).FMR1 does not produce enough protein (FMRP) that works cell communication.; Normal X genes that control FMR1 levels have promoter regions consisting of about 6 to 40 CGG; Fragile X genes.

Fragile X Syndrome is an inherited disorder caused by genetics that affects a child's learning, behavior, appearance, and health. Learn more about the symptoms, causes, diagnosis, and treatment of.

Fragile X syndrome, also known as Martin-Bell syndrome, is a genetic syndrome and the most common form of inherited mental retardation, especially in males. Impairments caused by fragile X syndrome are ranging from learning disabilities to more serious cognitive and intellectual disabilities.

Fragile X syndrome most commonly manifests as autism. Fragile X syndrome is an X-linked condition. X-linked conditions occur when there is a genetic variation on the X-chromosome. For these conditions, the sex of the parent who passes on the gene variation influences the risk for the children.

If the father is affected, all his daughters will have a variation on one of their X-chromosomes and be. Fragile X syndrome is a genetic disorder characterized by a moderate degree of intellectual disability. It is caused by a mutation in a gene located on the X chromosome, which makes the X chromosome appear constricted under the microscope; hence the condition was termed as Fragile X syndrome.

Book Appointment. Fragile X Syndrome: Symptoms, Causes, Diagnosis, and Treatment. Fragile X syndrome affects a child’s learning, behavior, appearance, and health. Symptoms can be mild or more severe. Boys often have a more serious form of it than girls.

The X chromosome is one of two sex chromosomes (the other being the Y chromosome). Males have one X and one Y chromosome; females have two X chromosomes. The male who receives the fragile-X chromosome will be affected by the syndrome, which is thought to be one of the major causes of intellectual disability in males.

About one-third of the females who receive one fragile-X chromosome. When there is a mutation or change in the gene called the Fragile X Mental Retardation1 (FMR1), Fragile X will occur.

The FMR1 gene produces a protein which is needed by the body in order for the brain to develop properly. If the body does not produce enough of the protein or produces none at all, Fragile X syndrome will develop.

Fragile X syndrome is a genetic disorder caused by a change to one of the genes on the X chromosome. It is the most common inherited cause of intellectual disability. Fragile X syndrome is also linked to features of autism spectrum disorder. Fragile X syndrome affects around 1 in 3, boys and between 1 in 4, – 6, girls.

Get this from a library. Facts about fragile X syndrome. [National Institute of Child Health and Human Development (U.S.);]. Fragile X Syndrome: From Genetics to Targeted Treatment provides a structured overview of the molecular and clinical background of the disorder as well as treatment options.

The book discusses the detailed molecular information on each of the pathways involved with sufficient details for all whose research touches this pathway.

Fragile X Syndrome Treatment Cause Of FXS - There is no cure for FXS. -Symptoms can be treated. -Often special education, different kinds of therapy and certain medications are used to target symptoms from a young age. - FXS is caused by having mutations to a gene in the X.

This gene is found on the X chromosome, one of the two chromosomes (X and Y) that determine gender. In people with fragile X, a particular section of the DNA code — CGG — is "fragile" and gets repeated an unusually large number of times, compared with the normal 5 to 50 times.

Nearly all cases of fragile X syndrome are caused by an alteration (mutation) in the FMR1 gene where a DNA segment, known as the CGG triplet repeat, is expanded. Normally, this DNA segment is repeated from 5 to about 40 times. In people with fragile X syndrome, however, the CGG segment is repeated more than times.

These Fragile X Syndrome 5 characteristics can consist of prominent ears and forehead, high palate, flat feet, and flexible finger joints (FX Syndrome, ).

Although many characteristics are similar to Downs Syndrome, children with Fragile X have been found to have fewer mistakes in many areas of speech than the children with Downs Syndrome. Fragile X syndrome (FXS), also known as Martin-Bell syndrome, is the most common cause of inherited intellectual disability.

FXS is caused by a change in a gene on the X chromosome. This change results in an inability to make a protein needed for normal brain development.

FXS affects both males and females, but is more common in males. Fragile X Syndrome. FXS is a single gene, X-linked neurodevelopmental disorder with an estimated prevalence of 1 in 4, males and 1 in 8, females (Sherman, Pletcher, & Driscoll, ; Turner, Webb, Wake, & Robinson, ).FXS is caused by an expansion of the cytosine-guanine-guanine trinucleotide repeat on the Fragile X Mental Retardation-1 (FMR1) gene located on the long arm of the X.

1. Introduction. The fragile X mental retardation 1 gene (FMR1) which causes fragile X syndrome if fully mutated (more than CGG-repeats in the polymorphic region- 5′UTR), was discovered in This discovery led to the description of premutation carriers (individuals with smaller alleles, 55– CGG repeats) and was followed by a better understanding of the transition propensity.
