AD : Likely Pathogenic | Substitution | Substitution | Missense | Coding | Exon 7 | Unknown; MRI showed focal atrophy in the medial temporal lobe; SPECT showed bilateral hypoperfusion in temporoparietal regions. |
Increased Aβ42 and the Aβ42/Aβ40 ratio in cells, without significantly altering Aβ40 levels. |

| S175F |
AD : Not Classified | Substitution | Substitution | Missense | Coding | Exon 7 | Unknown, but in one case brain imaging showed atrophy and hypometabolism consistent with AD. |
Unknown, but multiple in silico algorithms suggest it is damaging. |
