As with any information, genetic profiles can be used for good or ill. One suggestion is that presenting your children with a DNA map is a gift that they can use to safeguard against possible diseases in their future.

Tests are available to determine the genetic probability of several types of cancer, cystic fibrosis, and blood-clotting disorders, among other things. Knowing one’s probability for diseases or other health problems could prompt people to get advance screenings when treatment could make a difference, Phelan said. And assembling a family DNA profile could make future generations aware of their susceptibility to various diseases.”
