(none catalogued)

Position 533 sits in a transmembrane helix (Transmembrane helix 8). Wolframin has eleven such helices anchoring it in the ER membrane; substitutions inside the bilayer-embedded segments can disrupt helix packing, lipid contacts, and the overall ER topology of the protein. The wild-type residue is rigid/helix-breaking (proline — kinks backbone); the mutant is medium hydrophobic (leucine — branched). The chemistry shift implies altered local packing, hydrogen-bonding, and/or electrostatics at this site.

Final Schema Categorization

Category 3/4 — Most Druggable

<strong>Category 3/4 — Most Druggable</strong><br/><br/>|ΔΔG|=0.01 < 2 kcal/mol (fold intact) + AlphaMissense 0.978 confirms functional impact. Specific local contacts disrupted — priority for docking and pharmacological chaperone screening.

Why this card matters. Wolframin's fold survives this substitution (|ΔΔG|=0.01 kcal/mol). The pathogenic signal is real — AlphaMissense places it at 0.978. Protein still folds, but a specific local site is broken. Pharmacological chaperones and small-molecule binders are the rational therapeutic vector.
