Findings

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

Previously, this variant was reported in one of 676 controls and none of 332 cases in a sample of North American and British Caucasians (Sassi et al., 2016).

The variant also was reported in one of 927 late-onset Alzheimer’s cases, none of 852 early onset cases, and none of 1273 controls from the Alzheimer Disease Exome Sequencing France (ADESFR) project (Campion et al., 2019). THE ADESFR was one of the cohorts included in the 2022 study cited above.

Functional Consequences

The variant was predicted to be tolerated by SIFT and benign by PolyPhen-2 and was classified as a polymorphism by Mutation Taster (Sassi et al., 2016).
