But because of the gene's large size and the high number of possible mutations that can occur, genetic testing is usually not practical - and very expensive. contraindicaciones viagra y alcohol Physicians usually won't recommend genetic testing for two simple reasons: a diagnosis of nf1 is fairly easy to confirm on the basis of its physical signs, and genetic testing offers no extra benefits for treatment at this time. One exception to this is for people who have a family history of nf1. the safest viagra If another family member has been tested, and the mutation has been identified, then it becomes relatively easy to look for that same mutation in other family members.
