The fate of prematurely condensed chromosomes (PCC) that are induced following fusion between a mitotic and an interphase cell was studied in the homokaryons of HeLa and 2 glycine-requiring mutants of Chinese hamster ovary cells. The data indicate: (1) the prematurely condensed chromosomes are often incorporated into daughter nuclei of the fused cells and hence they are functionally retained by...

We report on a phenotypically normal 41-year-old azoospermic man with a 45 chromosomes karyotype including one normal chromosome 21, one normal chromosome 22, and a der(22)ins(22;21). Array CGH showed a 1.8 Mb terminal deletion of bands 21pter to 21q21.1 and a 341 kb terminal deletion on band 21q22.3.
