We review previous work on neutrino mass textures in gauge theories. Such textures may arise as a result of flavour symmetries. In a given theory, it is possible to give a classification of heavy Majorana neutrino mass matrices, assuming the Dirac masses of the neutrinos to be of the same form as the ones of the upquarks. Heavy Majorana neutrino mass matrices leading to three degenerate neutrinos, are tabulated as an example.
