The human glucagon gene is located on chromosome 2

DNA samples prepared from a panel of human-mouse cell hybrids with different numbers and combinations of human chromosomes were examined for the presence of the human preproglucagon gene by hybridization with a cloned segment of the human gene. The segregation of the human glucagon gene specific DNA fragment and human chromosome 2 in these cell hybrids indicated that the preproglucagon gene (designated GCG) is on chromosome 2 in humans.
