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 among the controls (Holstege et al., 2022).

Previously, the T1511I variant was seen in both Alzheimer’s patients and unaffected individuals in a family- and cohort-based study of Caribbean-Hispanics (Vardarajan et al., 2015). Joint linkage and association analysis, an analytical method that allows researchers to analyze together data from families and unrelated subjects, indicated that this variant associated with Alzheimer’s disease.

Functional Consequences

The variant was predicted to be benign by PolyPhen-2 (Vardarajan et al., 2015).
