Findings

This single-nucleotide deletion, within exon 1, results in a frameshift. It was discovered in an Alzheimer’s patient with early onset disease (age of onset 50 years) and APOE genotype E3/E4, in a study that included 484 French early onset AD cases recruited by the French National CNR-MAJ consortium and 498 ethnically matched controls (Nicolas et al., 2016). The patient’s family history included at least one first-degree relative with AD.

No additional carriers were found among 15,808 AD cases and 16,097 controls in a study that combined data from multiple European and American cohorts, including CNR-MAJ (Holstege et al., 2022).
