APP V695 Mutations
| Mutation | Pathogenicity | DNA Change | Expected RNA | Protein Consequence | Coding/Non-Coding | Genomic Region | Neuropathology | Biological Effect | Primary Papers |
|---|---|---|---|---|---|---|---|---|
| F690_V695del (Uppsala deletion, APP Δ690-695, APP delta690–695, Uppsala APP deletion) |
AD : Pathogenic | Deletion | Deletion | Deletion | Coding | Exon 17 | One reported carrier of this variant had autopsy-confirmed AD. |
Appears to largely eliminate non-amyloidogenic processing of APP and leads to the generation of rapidly aggregating Aβ peptides lacking amino acids 19-24. In mice, Aβ fibrils barely evoke a glial response. |

| V695M |
AD : Not Classified | Substitution | Substitution | Missense | Coding | Exon 17 | Unknown. |
Unknown. In silico algorithms yielded mixed results, but integrative PHRED-scaled CADD score was > 20, suggesting deleterious effect. |
