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).

In a French cohort of 852 early onset Alzheimer’s disease cases, 927 late-onset cases, and 1273 controls from the Alzheimer Disease Exome Sequencing France (ADESFR) project, one patient with early onset AD was found to be a heterozygous carrier of this variant (Bellenguez et al., 2017). The ADESFR contributed to the 2022 study cited above.

Functional Consequences

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