We study the dependence of the $D_{ s0}(2317)$ mass on the light quark mass through the analysis of data from QCD lattice simulations. Combining HH$\chi$PT and model selection tools as the LASSO method we fit the lattice data of the low-lying charmed mesons masses, obtaining their extrapolation to the physical point and extracting results for the quark mass dependence of the exotic resonances $D_{ s0}(2317)$ and $D_{ s1}(2460)$, taking as input the energy levels from a lattice simulation.
