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.
Epidermolysis bullosa simplex?
Hello, I see you are asking "What are the causes for epidermolysis bullosa?" EB is caused by a faulty gene (gene mutation) that makes skin more fragile. A child with EB might have inherited the faulty gene from a parent who also has EB. Or they might have inherited the faulty gene from both parents who are just "carriers" but don't have EB themselves.

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 there a certain age for fragile x syndrome to occur?
Fragile X is a genetic abnormality which is inherited and individuals therefore have the condition from birth, although, depending on the severity of the symptoms it is often undetected until early childhood. The average age of diagnosis is 8 years old. If however, parents are known to be carriers of Fragile X, the child may be given a blood test early on which is used to diagnose fragile x.
What cause fragile X syndrome?
The fragile X syndrome is a genetic disorder caused by mutation of the FMR1 gene on the X chromosome.
What do chromosome do?
In simple words, Chromosomes are the carriers of the gene or unit of heredity.
What are some specific studies of gene silencing?
Gene silencing has several specific studies including Meiotic, Transcriptional, Post-transcriptional, and Cellular components of gene silencing. Gene silencing is basically when scientists turn off a gene, so to speak.
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.
Is fragile X syndrome related to klinefelster?
No, Klinefelter is due to an extra chromosome, Fragile X is due to the FMR1 gene being turned off and producing no FMR1 protein
What has the author E Gene Frankland written?
E. Gene Frankland has written: 'Global Studies'
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.
What carriers that are related to biology?
carriers are a parent carrying the particular recessive gene for a disease but is not affected by that disease. However, its offspring will have that gene as dominant increasing its chances of being affected by that disease if the parent mates with another parent of the opposite gender who is also a carrier.
