Findings

A control subject was found to be a heterozygous carrier of this variant in a group of 1273 controls, 927 late-onset Alzheimer disease cases, and 852 early-onset AD cases from the Alzheimer Disease Exome Sequencing France (ADESFR) project (Bellenguez et al., 2017).

In a study that included 15,808 Alzheimer’s cases and 16,097 control subjects from multiple European and American cohorts, including ADESFR, this allele was observed once among the controls (Holstege et al., 2022).

Functional Consequences

The variant was predicted to be damaging by SIFT, Mutation Taster, and PolyPhen-2 (Bellenguez et al., 2017).
