In replication analyses, 21 genes showed nominal support in UK Biobank and Alzheimer's Disease Genetics Consortium (ADGC) cohorts, with eight genes (TREM2, ACADS, MFSD12, NUP210L, PIEZO2, PSEN1, SMURF2, AKAP13) supported under identical masks. This evidence concerns the gene SMURF2 and early-onset autosomal dominant Alzheimer disease.
