The assessment of SNVs residing in the nine AD genes using the gnomAD dataset revealed that some alleles that belonged to FGFR3, KRAS, PTPN11 and SETBP1 SNVs, which had evidence of mosaicism based on ExAC’s exome data, have been removed from the gnomAD dataset by gnomAD filters (Table 2). Here, KRAS is linked to Alzheimer disease.
