Computational Predictions
Clinical Evidence
Observed at very low frequency in gnomAD.
Structural Context
Position 824 in lumenal domain. Neighbors: PHE825 (2.4 Å — W700-F825 π-stacking partner!), ILE823 (2.5 Å), TRP700 (3.5 Å — direct contact with W700 Cat 2 region!), SER846 (3.7 Å).
E824 sits in direct contact with W700 and F825 — the same aromatic cluster identified in W700C and T699P Atlas cards. The wild-type E824 negative charge contributes to this microregion. Charge-flipping to K824 disrupts the local environment supporting W700-F825 π-stacking.
Mild ΔΔG; AM 0.566 borderline + DFNA6 confirm severe consequence.
Druggability Assessment
Mechanism: charge-flip in the W700-F825 aromatic cluster. Therapeutic: same W700-F825 microregion (with W700S/C, T699P/M).
