Findings

In a Dutch sample of 640 Alzheimer’s cases and 1268 controls, a 54-year-old AD patient was found to be a heterozygous carrier of the I351I variant. The variant was not seen in a cohort of 1255 early onset AD cases and 1938 age-matched controls from the European Early Onset Dementia Consortium (Holstege et al., 2017).

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