Diagnosing Genetic Disorders


Dr. Murray Barr co-discovered an inactive chromatin linked to genetic disorders such as Down’s, Klinefelter’s and Turner syndromes. The discovery of the chromatin, known as the Barr Body, led to a simple diagnostic test for certain genetic abnormalities. It also spurred new research into genetically caused diseases.

The Western University researcher’s study of sex chromatin bodies helped us better understand and manage certain genetic disorders, including those associated with cognitive problems.
