Fragile X syndrome is a genetic disorder that affects a person from birth. This is brought to you for free and open access by the Student Theses & Publications at The Keep. It is caused by a mutation of the FMR-1 (fragile-X mental retardation) gene located on the X chromosome. The exact number of people Fragile X syndrome is most common in females. It can cause a variety of mental effects ("Fragile X syndrome", 2017). Cognitive Characteristics While many children with fragile X score in the mentally retarded ranges on standardized tests, Fragile X syndrome affects about 1 in 4,000 males and between 1 in 5,000 and 1 in 8,000 females. Fragile X syndrome (FXS), a genetic condition known to be the most common form of inherited intellectual limitation in men, was initially seen as a single disorder associated with mutations in the fragile X mental retardation (FMR1) gene on the X chromosome. The spectrum ranges from learning disabilities to severe cognitive impairment (formerly . One of the characteristics of Fragile X syndrome is an impairment of this homeostatic control of arousal.

It appears in people of all ethnic, racial and socio-economic backgrounds and can affect both genders . Fragile X syndrome can differ from case to case in the severity of the disorder. It arises from the silencing of the fragile X mental . The average IQ in males with FXS is under 55, while about two thirds of affected females are intellectually disabled. This expansion causes a certain region of the X chromosome to repeat over and over again. Fragile X occurs across every culture and is not related to the age of the mother at the time of conception. Fragile X, whether you have the syndrome or not, affects the everyday lives of many. Fragile X syndrome is a genetic disorder that affects a person from birth. Some children are very obviously affected, whereas others have more subtle symptoms. But some children with Fragile X syndrome might have the following physical features: long and narrow face; prominent ears What Are the Symptoms of Fragile X?

CDC is working to learn more about fragile X syndrome and fragile X-associated disorders to improve the health and well-being of people with these conditions. Fragile X syndrome is a genetic disease characterized by the expansion of a region of the X chromosome. An excess number of repeats will determine what degree of the disease is present. When discussing Fragile X syndrome and behavior, it is important to note that - like every person - the focus should not only be on the challenging behaviors that you may see. The vast majority of individuals who have fragile X syndrome have not been diagnosed, and family members who carry the trait are unaware their unborn children could be at risk. Fragile X syndrome is caused by a change to a gene on the X-chromosome called the FMR1 gene. Depending on the FMRP concentration, a clinical spectrum develops.

As no consistent craniofacial abnormalities had been reported in animal models, we analysed micro-CT images of the fragile X mouse model. Fragile X syndrome is the most common cause of inherited mental impairment. A DNA part called the "CGG triplet repeat" expands within a gene called "FMR1," producing a mutation that causes fragile X syndrome. It is also the most common single gene cause of Autism Spectrum Disorder worldwide. In addition, they exhibit facial characteristics including a long narrow face, prominent ears and a high-arched palate. Around one third of people with Fragile X have enough of these characteristics to meet the criteria to be diagnosed with autism.

This contribution explores the genetic and molecular basis of the disease and methods for its detection, as well as neuropathological findings. Fragile X syndrome (FXS) is the most common known inherited cause of intellectual disability, learning disability, and autism spectrum disorder (ASD), with an estimated prevalence of about 1/4,000 ().Individuals with FXS display variable physical features such as large ears, long face, macrocephaly, macroorchidism, and variable levels of functioning, with a fairly stereotyped . Physical Characteristics There are some physical features associated with Fragile X, including a long narrow face with prominent jaw bones and ears however, these are rarely obvious in young children. FXS is caused by a mutation in a single gene on the long arm of the X chromosome. Therefore, a child who has speech/language or learning problems, in addition to any other characteristics typical of fragile X syndrome, should be referred for a more formal evaluation. About a third of those affected have features of autism such as problems with social interactions and delayed speech. Many people that suffer from Fragile X have long, narrow faces, large ears, and tend to be double jointed.

Fragile X syndrome (FXS) is an inherited genetic disease passed down from parents to children that causes intellectual and developmental disabilities. It is essential that parents look at the whole person. Of the 1,394 individuals (1,090 males and 304 females) with the full mutation, 14% of males and 6% of females reported seizures. Fragile X syndrome can differ from case to case in the severity of the disorder. It is caused by a CGG trinucleotide repeat expansion in the FMR1 gene on the X chromosome. Males are usually more severely affected than females. Fragile X syndrome (FXS) is the most common identifiable cause of inherited intellectual disability and autism spectrum conditions, and is associated with a range of physical, cognitive and behavioural characteristics. Yet, cluttering has not been systematically characterized in this population, hindering identification and intervention efforts. A normal part repeats five to 40 times, but in people with fragile X syndrome it repeats more than 200 times. Children with Fragile X Syndrome also present with a number of challenging characteristics.
