Can carriers of fragile X have symptoms?
A fragile X carrier is someone who has an altered FMR1 gene, but does not show any obvious signs or symptoms of fragile X syndrome. Women who are fragile X carriers have up to a 50 percent chance of having a child with fragile X syndrome.Which parent is the carrier for fragile X syndrome?
The gene for Fragile X is carried on the X chromosome. Because both males (XY) and females (XX) have at least one X chromosome, both can pass on the mutated gene to their children. A father with the altered gene for Fragile X on his X chromosome will pass that gene on only to his daughters.How do you test for fragile X carrier?
DNA studies are used to test for fragile X syndrome. Genotypes of individuals with symptoms of FXS and individuals at risk for carrying the mutation can be determined by examining the size of the trinucleotide repeat segment and the methylation status of the FMR1 gene.- Physical health symptoms such as chronic fatigue, chronic pain, fibromyalgia, autoimmune disorders, and sleep problems have also been identified at higher rates in people with the Fragile X premutation.
