System Design Key Features Instructions Protocols Materials PCR Protocol DNA Measurement Protocol Research and Development Background on Disease Markers A very large disease that is wide spread all around the world is Alzheimer’s. Nearly one in every 85 people around the world has this disease. On average, one’s life will end seven years after the diagnosis. Fewer than three percent of patients live longer than fourteen years after the determination of the presence of Alzheimer’s. Of the type of Alzheimer’s that is autosomal, the DNA produces a protein that is different than the expected one. This misfolded protein causes the disease. The DNA sequence that codes for the specific amino acids that form these mutated proteins are called SNPs. An Alzheimer’s related SNP is called rs429358. It exists on the 19th chromosome of the human genome. More information about this SNP can be found by looking up the reference number, rs429358, on OMIM. The normal sequence appears TGC while the mutated Alzheimer’s sequence will show CGC. The respective amino acid produced changes from Cysteine to Arginine. This change in amino acid, causes the proteins to fold differently. Primer Design The reverse primer for this gene would be: GGCGGCCGCACACGTCCTCCCA. The critical sequence begins at 45,411,950 on the 19th chromosome. Now looking 200 base pairs to the left, a forward primer can be created. In this case it would go as follows: CATCCCAGCCCTTCTCCCGC.
