We update a five-dimensional SO(10) grand unified model of fermion masses andmixing angles originally proposed by Kitano and Li. In our setup Yukawacouplings are anarchical and quark and lepton sectors are diversified by theprofiles of the fermion zero modes in the extra dimension. The breaking ofSO(10) down to SU(5) \times U(1)_X provides the key parameter thatdistinguishes the profiles of the different SU(5) components inside the same 16representation. With respect to the original version of the model, we extendthe Higgs sector to explicitly solve the doublet-triplet splitting problemthrough the missing partner mechanism and we perform a fit to an idealized setof data. By scanning the Yukawa couplings of the model we find that, for largetan\beta, both normal and inverted ordered neutrino spectrum can beaccommodated. However, while the case of inverted order requires a severe finetuning of the Yukawa parameters, the normal ordering is compatible with ananarchical distribution of Yukawa couplings. Thus, in a natural portion of theparameter space, the model predicts a normal ordered neutrino spectrum, thelightest neutrino mass below 5 meV, and |m_{\beta\beta}| in the range 0.1-5meV. No particular preference is found for the Dirac CP phase in the leptonsector while the right-handed neutrino masses are too small to explain thebaryon asymmetry of the universe through thermal leptogenesis.

Order and Anarchy hand in hand in 5D SO(10)
