So little is known about autism and asperger's that we cannot answer this question.

Where on the X chromosome does Fragile X take place?

Fragile X is a result of a mutation in the FMR1 gene on the X chromosome.


Is fragile-x-syndrome due to heredity or is it a mutation?

mutation


Does fragile x syndrom have a mutation?

Yes, fragile X syndrome is caused by a mutation in the FMR1 gene on the X chromosome. This mutation leads to a lack of production of a protein called FMRP, which is essential for normal brain development.


What cause fragile X syndrome?

The fragile X syndrome is a genetic disorder caused by mutation of the FMR1 gene on the X chromosome.


When does a fragile X premutation become a full mutation?

Once the size of the premutation exceeds 230 repeats, it becomes a full mutation and the FMR-1 gene is disabled. Individuals who carry the full mutation may have fragile X syndrome


Why are males more likely to have fragile X syndrome?

males have only one copy of the X chromosome. Males who inherit the full mutation are expected to have mental impairment. A female's normal X chromosome may compensate for her chromosome with the fragile X gene mutation


How many chromosome do you have when you have fragile x syndrome?

Fragile X syndrome is caused by a mutation that prevents the Fragile X mental retardation (Fmr-1) gene from being transcribed. This gene is located on the X chromosome (the sex chromosome). Since males only carry one of these chromosomes, they are twice as likely to be affected by the mutation than females.


How is Fragile X Syndrome Inherited?

Males and females can be carriers, male carriers can only pass on to their daughters, they will be carriers as well have a premutation. Females can pass on to their sons or daughters, they will have the premutation or the full mutation.


Fragile X syndrome affects only females?

No, Fragile X is on the X chromosome. Females have 2 X chromosomes and Males have an X and a Y Chromosome. Therefore, both males and females can have Fragile X (they can have the full mutation or be carriers). Males are usually more severly affected because they have only one X Chromosome.


What causes disease fragile x?

The fragile X syndrome is a genetic disorder caused by mutation of the FMR1 gene on the X chromosome.Expansion of the CGG repeating codon to such a degree results in a methylation of that portion of the DNA, effectively silencing the expression of the FMR1 protein.Mutation of the FMR1 gene leads to the transcriptional silencing of the fragile X-mental retardation protein, FMRP.


How many people in the world are fragile x carriers and what is their origin?

Fragile X syndrome is caused by a mutation in the FMR1 gene, and approximately 1 in 260 women and 1 in 800 men are carriers of the mutation globally. The prevalence can vary by population, with higher carrier rates observed in certain ethnic groups, particularly those of European descent. The origin of the fragile X mutation is believed to date back several generations, with the expansion of CGG repeats in the FMR1 gene being the primary cause. This genetic condition is inherited in an X-linked manner, meaning it is passed down through families.


Is fragile x a x linked disorder?

Yes, Fragile X syndrome is an X-linked genetic disorder that causes a range of developmental problems. It is caused by a mutation in the FMR1 gene located on the X chromosome. The condition is more commonly seen in males than in females because they have only one X chromosome.
