title: Expression of galactose-1-p-uridyltransferase in Chinese hamster x human galactosemia somatic cell hybrids.
abstract: Lymphocytes from a patient with classic galactosemia (GALT deficiency) were hybridized with a Chinese hamster cell line.  Electrophoretic valuation of GALT in 31 independently derived interspecific hybrid clones failed to demonstrate expression of the human GALT gene even when human chromosome 9 was present. Possible mechanisms for this lack of expression are presented.
