Abstract
Medical genetics as a discipline has contributed basic knowledge of great applicability in environmental medicine, e.g. 1) the demonstration that environmental agents may cause chromosomal damage, 2) that chromosome aberrations are correlated with increased risks for cancer and spontaneous abortion, and 3) that the susceptibility to cyto- and genotoxic damage may be influenced by genetic factors. This paper discusses examples of applications of genetic knowledge in environmental medicine and areas for future research.
