title: Recent advances in the molecular analysis of inherited disease.
abstract: Many important human genes have been cloned during the last ten years. In some cases, using reverse genetic techniques [Orkin, S. H. (1986) Cell 47, 845-850], disease-causing genes have been isolated whose product was previously unknown. Important examples include the dystrophin protein which, when mutated, gives rise to either Duchenne or Becker muscular dystrophy [Koenig, M., Hoffman, E. P., Bertelson, C. J., Monaco, A. P., Feener, C. and Kunkel, L. M. (1987) Cell 50, 509-517; Monaco, A. P., Bertelson, C. J., Liechti-Gallati, S. & Kunkel, L. M. (1988) Genomics 2, 90-95; Koenig, M., Monaco, A. P. & Kunkel, L. M. (1988) Cell 53, 219-228] and the cystic fibrosis transmembrane conductance regulator (CFTR) [Riordan, J. R., Rommens, J. M., Kerem, B.-S., Alon, N., Rozmahel, R., Grzelczak, Z., Zielenski, J., Lok, S., Plavsic, N., Chou, J.-L., Drumm, M. L., Ianuzzi, M. C., Collins, F. S. & Tsui, L.-C. (1989) Science 245, 1066-1073]. Recently the technology for systematically detecting single base-pair changes by chemical methods, enzymatic methods or direct DNA sequencing has greatly expanded and simplified. In addition to providing structural information about these clinically important genes and information on disease-causing mutations, these studies have led to an increased understanding of mechanisms of mutation, to the discovery of novel genetic mechanisms and to important clinical applications of carrier detection and pre-natal diagnosis. The recent rapid progress has been made possible by the development of DNA amplification using the polymerase chain reaction (pcr) invented by Saiki and colleagues [Saiki, R. K., Chang, C-A., Levenson, C. H., Warren, T. C., Boehm, C. D., Kazazian, H. H. & Ehrlich, H. A. (1988) N. Engl. J. Med. 319, 537-541].
