[quote=Anonymous][quote=Anonymous]Fragile X is a recessive trait that can cause intellectual disabilities. OP: If you are worried about this, your intended and you can have genetic testing for these things. National Children's did mine. I didn't marry my cousin but did come from a family with known fragile X and I wanted to make sure I was not a carrier. Genetic testing is kind of fun. [/quote] Fragile X is x-linked, not recessive. It also gets worse as the mutation is passed from generation to generation (the term for this is anticipation). Females are generally unaffected because they have two copies of the X chromosome. But it is not a classic recessive disease, which requires inheritance of two mutated copies of the gene to cause disease. Affected males have one X chromosome that carries the mutation. [/quote]
