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 once among the AD cases (Holstege et al., 2022).

A previous report from the European Early-Onset Dementia Consortium identified one of 1255 AD cases and two of 1938 controls as heterozygous carriers of the M1697I variant (Verheijen et al., 2016).

The M1697I variant is classified as likely benign by the criteria of Holstege et al. (Holstege et al., 2017).

Functional Consequences

The M1697I variant was predicted to be tolerated by SIFT, neutral by Mutation Taster, and benign by PolyPhen-2 (Campion et al., 2019).
