Findings

This variant was found in a cognitively healthy African individual from the Bantu population. It alters a residue that is not conserved between PSEN1 and PSEN2 (A137 in PSEN1), and is located in the second transmembrane domain of the protein. It is thought to be a benign polymorphism (Guerreiro et al., 2010).

Neuropathology

Not applicable.

Biological Effect

Unknown.
