Findings

In a Dutch sample of 640 Alzheimer’s cases and 1268 controls, an 85-year-old control subject was found to be a heterozygous carrier of this synonymous variant. No additional carriers were found in a pan-European cohort of 1255 cases and 1938 controls from the European Early Onset Dementia Consortium (Holstege et al., 2017).

The D1304D variant is classified as likely benign by the criteria of Holstege et al. (Holstege et al., 2017).
