The strongest biomarker-oriented hypothesis is not that Rab12 is the main pathogenic target, but that pRab12 may outperform pRab10 as a translational readout under chronic lysosomal stress or disease-relevant compartmentalization. This could reflect substrate usage, compartment retention, or reduced phosphatase masking, making paired pRab12:pRab10 measurements more informative than either alone.
The most supported model is that pathogenic G2019S shifts the basal catalytic set-point upward, producing higher baseline phospho-Rab output while leaving the core lysosomal volume-sensing response architecture largely intact. In this view, mutant cells begin from a higher activity floor, and the key experimental discriminator is whether baseline-normalized EC50, slope, or Emax materially increase during graded swelling.
