We determine the quark mass dependence - light and heavy - of the
Ds0(2317) properties, such as, mass, coupling to DK, scattering lengths
and compositeness, from a global analysis of DK energy levels from LQCD. In
particular, we analyze the HSC energy levels for DK scattering in I=0 for
different boosts and two pion masses. The formalism is based in the local
hidden-gauge interaction of Weinberg-Tomozawa type which respects chiral and
heavy quark spin symmetries, supplemented by a term that takes into account the
DK coupling to a bare csˉ component. The isospin violating decay of
the Ds0(2317)→Ds+π0 is also evaluated
