Title: Occurrence of aneuploidy for the X chromosome in over 1,300 unrelated specimens screened for the fragile X chromosome

Journal Article · · American Journal of Medical Genetics
OSTI ID:62053

An apparent association between the occurrence of the fragile X syndrome and Klinefelter and Down syndromes has been reported over the past few years. We reported 3 cells with extra X chromosomes [XXY (one cell), XXXY (2 cells)] in a fragile X male who exhibited 37 fragile X chromosomes in 200 cells studied. After making this observation, we decided to determine the number of X chromosomes in all fragile X chromosome analyses to see if there was any increased mitotic nondisjunction for the X chromosome. We conclude that there was no association between the fragile X syndrome and X chromosome mitotic nondisjunction/aneuploidy in this group of individuals. 9 refs., 1 tab.
