## Chromosome positioning is largely unaffected in lymphoblastoid cell lines containing emerin or A-type lamin mutations.

Gene-poor human chromosomes are reproducibly found at the nuclear periphery in proliferating cells. There are a number of inner nuclear envelope proteins that may have roles in chromosome location and anchorage, e.g. emerin and A-type lamins. In the last decade, a number of diseases associated with tissue degeneration and premature aging have been linked with mutations in lamin A or emerin. These are termed laminopathies, with mutations in emerin causing Emery-Dreifuss muscular dystrophy. Despite highly aberrant nuclear distributions of A-type lamins and emerin in lymphoblastoid cell lines derived from patients with emerin or lamin A mutations, little or no change in chromosome location was detected.
