With the particle content of the 27 representation of ${\mathrm{E}}_6,$ a skew left-right supersymmetric gauge model was proposed many years ago, with a variety of interesting phenomenological implications. The neutrino sector of this model offers a natural framework for obtaining small Majorana masses for ${\nu }_e,$ ${\nu }_{\mu },$ and ${\nu }_{\tau },$ with the added bonus of accommodating 2 light sterile neutrinos.
