Findings

In a North American study, the L205P variant was found in one of 210 Alzheimer’s patients and none of 233 controls (p = 0.45) (Ghani et al., 2016).

Neuropathology

No data.

Biological Effect

The leucine-to-proline substitution at amino acid 205 was predicted by SIFT to be damaging, but by Polyphen2 to be benign (Ghani et al., 2016).
