Abstract: The present invention provides methods and compositions to dedifferentiate a cell. The ability of the methods and compositions of the present invention to promote the dedifferentiation of differentiated cells, including terminally differentiated cells, can be used to promote regeneration of tissues and organs in vivo. The ability of the methods and compositions of the present invention to promote the dedifferentiation of differentiated cells, including terminally differentiated cells, can further be used to produce populations of stem or progenitor cells which can be used to promote regeneration of tissues and/or organs damaged by injury or disease. Accordingly, the present invention provides novel methods for the treatment of a wide range of injuries and diseases that affect many diverse cell types.

Abstract: A method is disclosed for diagnosing Hereditary Neuropathy with Liability to Pressure Palsies (HNPP). A submicroscopic deletion of about 1.5 million basepairs on chromosome 17p11.2 is associated with the disorder in three unrelated pedigrees. The deletion includes all the markers known to map within the Charcot-Marie-Tooth type 1A (CMT1A) duplication. The method involves detecting the presence or absence of the deletion in DNA extracted from a patient sample. The deletion may be detected by Southern analysis or fluorescence in situ hybridization analysis (FISH). Sequences or probes that may be used to detect the deletion are provided, as are components of a kit for diagnosing HNPP.
