Conclusions

Based upon the graph and the data, Patient 2 is positive and Patient 1 is negative. This is supported by the graph because Patient 2's data values lie above the line of best fit while Patient 1's data value lie below the regression line.



SNP Information & Primer Design

Background: About the Disease SNP

The disease is located on chromosome 21:34370656 on the KCNE2 gene. KCNE stands for potassium voltage-gated channel and joins with KCNH2 gene product, which is a pore forming protein, and alters its function. The mutation is a single nucleotide polymorphism and it is pathogenic in nature. It causes a Cardiovascular disease called Long QT syndrome. This mutation is found in Homo Sapiens by changing the genes that are responsible for encoding the ion channels present within the heart. The normal allele is TTC but it changes to CTC when a person has the disease.

Primer Design and Testing

By inputing the non-disease forward primer and reverse forward primer the PCR database successfully matched the sequence meaning it is found in the healthy human genome. When the disease SNP was inputed with the single nucleotide change, the database could find no matches.
