Location of Asp78, Gln79, and Asp95 within the protein S Gla-TSR-EGF1 model. Domains are labeled on the right side of the model. Residues mutated in the GLA2 variant, Asp78, Gln79, and Asp95, are in light gray on the left side surface model. Residues Asp78, Gln79, and Asp95 are highlighted by the box to show their proximal spatial location. The model is taken from Villoutreix et al.35
