title: A girl with an end-to-end fusion of two X'S.
abstract: An abnormal large chromosome was seen in the karyotype of a 3-year-old girl with features of Turner's syndrome: i.e., short stature, cubitus valgus, coarctation of aorta. With the banding technics this abnormal chromosome appears to be the result of a fusion of two X chromosomes, short arm-to-short arm. This chromosome has two regions with C-heterochromatin and is late replicating.
