The most common conditions that are caused by a x-linked recessive gene variant are hemophilia, duchenne muscular dystrophy and fragile X syndrome. In this case usually female genetic carriers of an x-linked recessive condition do not develop health concerns by being a genetic carrier. Clues for why a female might be a genetic carrier for x-linked recessive gene variants include having a family history of the condition that usually only affects males, so that is important to have a genetic counseling.
