“You know, in a year or two we won't need any clinicians anymore who do genetics, you know, clinical geneticists.” I thought that was really pretty crazy because there are 23,000 genes, and there are only 8000 or so diseases known to be associated with those genes, so there are bound to be many, many more discovered, and then there are variations, and so we'll always need people to discover new diseases associated with genes and new therapies and to identify the variants in those particular disorders.
