  In this work we demonstrate how Scotogenic model can arise naturally from an
$SU(7)$ grand unified theory. Our model also includes a low scale Pati-Salam
$SU(4)_c\times SU(2)_L\times U(1)_R$ symmetry which unifies quarks and leptons.
$\mathbb{Z}_2$ symmetry needed for the realization of Scotogenic scenario is a
residual symmetry and not $ad$ $hoc$. A short fermion masses and dark matter
analysis is included.
