Mitotic and meiotic instability of a telomere association involving the Y chromosome.

Abstract

Constitutional telomere associations and jumping translocations (JTs) are rare events and usually occur post-zygotically. We report a telomere association involving the Y chromosome which "jumped" during meiosis. A 21-year-old woman was referred for amniocentesis due to non-immune hydrops seen in a previous pregnancy.
