Findings

The variant was found in one of 5198 Alzheimer's cases and none of 4491 controls in a dataset from the Alzheimer’s Disease Sequencing Project (ADSP), consisting of subjects of non-Hispanic Caucasian ancestry from whom whole-exome sequencing data were available (Campion et al., 2019). The carrier was classified as having early onset AD.

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

Functional Consequences

The P1481R variant was predicted to be tolerated by SIFT, but deleterious by Mutation Taster and PolyPhen-2 (Campion et al., 2019).
