    Irene Uchida

    Irene Ayako Uchida, OC, geneticist (born 8 April 1917 in Vancouver, BC; died 30 July 2013 in Toronto, ON). Dr. Uchida pioneered the field of cytogenetics in Canada, enabling early screening for chromosomal abnormalities (i.e., changes in chromosomes caused by genetic mutations). 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. Click here for definitions of key terms used in this article.
