Construction of probe sequences for computational APP gencDNA screening. We searched for the same sequence of 2 bases at the 3′ end and 2 bases at the 5′ end. A probe sequence of 30 bases was created by combining 16 bases, including 2 homologous bases at the 3′ end and 16 bases including 2 homologous bases at the 5′ end, and removing one pair of 2 homologous bases. The probe sequence's construction region was the APP gene's coding region, and homologous regions at least 10 bases apart were selected. Probe sequences with identical sequences in the APP mRNA (APP transcript variant 1, Accession number NM_000484) and duplicates were removed, resulting in a final set of 182,654 probe sequences.
