Genetic Diseases In The 1950s

In the early 1900s, inherited diseases were first linked to chromosomes. Discoveries starting in the 1950s have helped scientists to develop genetic tests for genetic conditions such as Down syndrome, cystic fibrosis, and Duchenne muscular dystrophy. Genetic testing was initially used to make or confirm a diagnosis of a genetic condition, and to screen newborns for conditions such as phenylketonuria (PKU), so that early interventions and treatments could be administered. The screening of these genetic diseases led to appropriate assessment of the problem and assurance to the affected which are two of the core public health principles.
Currently, an example of genetic screening for familial hypercholesterolemia which came up in the 2000s is
