Findings
The E887G variant was identified in Caribbean Hispanics in a family- and cohort-based study (Vardarajan et al., 2015). Joint linkage and association analysis, an analytical method that allows researchers to analyze together data from families and unrelated subjects, showed that this variant associated with Alzheimer’s disease.
Functional Consequences
The variant was predicted to be benign by PolyPhen-2, but deleterious by SIFT (gnomAD, v2.1.1, accessed 2021-10-06).
