Irene Uchida

Irene Ayako Uchida, OC, geneticist (born 8 April 1917 in Vancouver, BC; died 30 July 2013 in Toronto, ON).

She discovered that women who receive X-rays during pregnancy have a higher chance of giving birth to a baby with Down syndrome and other chromosomal abnormalities. She also discovered that the extra chromosome that causes Down syndrome may come from either parent, not only the mother.
