Can fragile x syndrome be inherited? Fragile X syndrome (FXS) is a genetic disorder. A genetic disorder means that there are changes to the person’s genes. FXS, or the risk for developing FXS, can be passed down from parents to children through genes.
Which parent passes on Fragile X? 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 is fragile X disease inherited? This condition is inherited in an X-linked dominant pattern. A condition is considered X-linked if the mutated gene that causes the disorder is located on the X chromosome, one of the two sex chromosomes. The inheritance is dominant if one copy of the altered gene in each cell is sufficient to cause the condition.
How common is it to be a carrier of Fragile X? Anyone can be a carrier of fragile X syndrome. It is found among all ethnic backgrounds and racial groups. Approximately 1 in 250 women in the general population are carriers of the abnormal gene that causes fragile X syndrome.
