How does freidreich's ataxia differ from fragile x syndrome and myotonic distrophy?

Triplet repeats.... All three are caused by a form of genetic instability involving dna triplet repeats, however they affect three different genes and cause three different diseases: freidrich's = degenerative neuro-muscular disorder; fragilex = mental retardation and behavioral disorder; and myotonic = progressive muscle wasting and weakness.

How common is fragile x syndrome in us?

Depends on your dfn. Significant impairment (iq<70) in FAS is felt to represent 1/3600 of the population, mostly male. A lesser form of involvement with lesser alterations in this gene (add, behavior issues) may affect 1/130-250 female & 1/250-800 males.

I would like to know about fragile x syndrome?

Male dominated. The fragile x is named for a non staining region on the long arm of an x containing useless genetic material that results in mental impairment & physical changes(if you only have 1 x:males).The females usually show few if any features due to protection by a normal x, but not always & have a 50% chance of passing the fragile x to any offspring. This is a male dominated form of mental impairment. Read more...

What are the best ways to cure fragile x syndrome?

You don't. The fragile X defect exists in every cell of the person's body.The defective material has a variable effect on the function of each cell.There is no cure. Identification and support for intellectual challenges and any related health issues are the limit of current care. Read more...

Is there any drug available for fragile x syndrome?

No. The basic science evidence is that the affected chromosome is deficient in Folic Acid but that has not worked out clinically. Read more...
No. Those with this disorder have the abnormal chromosomal material in every cell of their body.There is no "pill" to correct its effects. The extra material is thought to confuse the cell by providing defective information as the cell tries to carry out its delicate metabolic functions.It is more important in some cells than others, which is why these individuals can appear so normal in most respects.

What number of people know what is fragile x syndrome?

A genetic disorder. Both males and females have an X chromosome (girls have two, boys have one and one Y chromosome). Fragile X is a genetic problem that causes a range of developmental issues, including learning disabilities. Males are more severely affected because they only have one copy of the X chromosome. They can have symptoms that resemble attention deficit disorder or learning issues. . Read more...

What happens to those with fragile x syndrome as an adult?

They grow up! Boys and girls with fragile x syndrome grow up to be men and women with fragile x syndrome: loved and loving people with full lives. Like many adults with disabilities, they need help with work, housing, food, transportation, and health care. A number of organizations, like the national fragile x foundation, can help. http://www.fragilex.org/treatment-intervention/adults-life-planning/. Read more...

Wondering if retardation in a teen boy is fragile x syndrome?

Delay. Fragile x syndrome is one of the most common reasons for inherited developmental delays in boys. Fragile x patients can be identified thru genetic testing and how they might look on physical exam. Such delays can be seen in lots of kids without a diagnosis of fragile x. So that means that boys w/developmental delays can't be labeled as fragile x, w/o genetic test confirmation. Read more...
Have chromosome test. to diagnose fragile X, a chromosome test is needed. There are other causes of retardation which might be diagnosable with other gene/chromosome related disorders. Read more...

What is the definition or description of: Fragile X syndrome?

Fragile X. Fragile X syndrome is a genetic disorder. The abnormality is found on mutation of the fragile X mental retardation 1 (FMR1) gene on the X chromosome. The mutation is repetition of FMR1 gene Affected males have intellectual and developmental delays and 33% of affected females have intellectual delays. Affected individuals may have large heads and long faces. Read more...
