What can you tell me about fragile x syndrome?

Fragile X: Fragile X syndrome is the leading known inherited cause of intellectual disability, and leading known genetic cause of autism and can cause developmental and language delays, learning impairment, and behavioral and mental health issues. Females who are carriers of the Fragile X gene mutation have a 50/50 chance of passing the mutation to each of their children. Other associated syndromes exist.

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.
