Use of the World Wide Web ("the web") and our knowledge of human genetics a
re both currently expanding rapidly. By allowing swift, universal, and free
access to data, the web has already played an important role in human gene
tics research. It has also begun to change the way that information is shar
ed in clinical genetics and, to a lesser degree, affect how education in hu
man genetics occurs. There are scores of web sites helpful to those interes
ted in either research or clinical aspects of human genetics. The web and r
elated communication technologies should continue to play increasingly impo
rtant roles in human genetics.
