Timeline
Middle Ages- infants with salty skin, a symptom of CF, said to be “bewitched”. Salty skin is a symptom of CF. Excessive amounts of salt can cause abnormal heart rythms and shock.
1908- Archibald Garrod says that some diseases are due errors in metabolism, resulting in a lack of a specific enzyme. This is significant because it shows that CF could be linked to genes in your body.
1936- Condition is named as Cystic Fibrosis, before this the condition had no name. This helped put a name to the condition many people faced.
1938- First list of CF symptoms is
created. This was created by
1949- Said that CF is a recessive genetic disorder. 2 genes must be present for Cf to appear in a patient.
1953- Sweat test, now the most
common test, is developed after a heat wave occurred in
1968- First successful embryo biopsy performed on a rabbit.
Early 1980’s- Researchers associate CF organ damage with epithelial tissue malfunction
Mid 1980’s- PGD for humans first
developed in the
1989- Discovery of the gene for CF,
known as CFTR. A hospital in
May 2001-current-About 30,000 Americans are said to have CF, this is according to the Cystic Fibrosis Foundation.
Also, more then 3,000 PGD clinical cycles in over 40 centers around the world.
