This variant was detected in a control individual in a study assessing 72 AD cases and 58 controls (Frigerio et al., 2015).  There was no family history of dementia. The age of the mutation carrier was not reported, nor were details regarding his or her cognitive health. Classification as a control was based on a lack of significant AD pathology in the brain.


Not applicable.

Biological Effect

Unknown. In silico, the A258T variant was predicted to be probably damaging by PolyPhen2.
