Findings

Two control subjects were found to be heterozygous carriers of this synonymous variant in a Dutch sample of 1268 controls and 640 Alzheimer’s cases. The variant was not seen in a pan-European cohort of 1255 cases and 1938 controls from the European Early Onset Dementia Consortium (Holstege et al., 2017).

The N1181N variant is classified as likely benign by the criteria of Holstege et al. (Holstege et al., 2017).
