Gene mapping and molecular pathology

The corresponding number of mapped genes
had risen to 928 by the ninth meeting in 1987 as molecular
techniques replaced those of traditional somatic cell genetics.
The total number of mapped X linked loci also rose, from 155
in 1973 to 308 in 1987. The number of mapped genes has
continued to increase rapidly since then, reflecting the
development of new molecular biological techniques and the
institution of the Human Genome Project.
