Pedigrees show the presence or absence of a trait as it relates to the relationship among parents, offspring, and siblings. In the future it may be possible to screen for newborns who have the mutations in the genes for neurexins and neuroligins that are associated with autism. What Tsien really showed was that manipulating the expression of a single gene coding for the subdomain of a neuroreceptor could increase learning ability in mice (Tang et al., 1999). For disorders, however, the ability to predict the likelihood of diseases can be vital for parents in family planning and early prevention or detection of disease.
