Background on Disease Markers Alzheimer's An SNP related to Alzheimer's disease is rs1466662 (http://www.ncbi.nlm.nih.gov/projects/SNP/snp_ref.cgi?rs=1466662). It is located on chromosome four, the intron region of NM_001142552.1 and arises from a missense mutation replacing an A with a T. It is the most significant SNP outside of the SNP linked to APOE.
The backwards primer is TAT TTT TAG AAG CGA TAA AA. The forwards primer is GCC TCT TTG CCC TCT GTT TT. An allele not containing the disease will not have the sequence that allows the primers to bind. If the primers cannot bind, then that means Taq polymerase does not know where to bind. If Taq polymerase does not bind, then the sequence does not get replicated. Therefore, there will be no PCR product. Conversely, if the disease allele is present, the primers will bind. Taq polymerase will then be able to bind to the DNA and replicate the strands, creating more double-stranded DNA yielding a PCR product.
