The cradle was then moved so that the phone was 12 cm away from from where the drop would be measured. Pieces of bubble wrap were placed in between the phone and the cradle so that the phone was level with the drop.

The green was mostly at the bottom, with blue at the top. Patient 1 had an average initial PCR product concentration of 24 μg/mL. Patient 2-19967 : All of the images for patient 2 were also bright green. The green fluorescence was shown all throughout the drop. Patient 2 had an average initial PCR product concentration of 18.869 μg/mL. Conclusions Patient 1-33849 : Patient 1 had an average initial PCR product concentration that was 3.84 μg/mL less than that of the product concentration of the positive sample, and 50.76 μg/mL greater than that the product concentration of the negative sample. Since Patient 1 had a concentration closer to the concentration of the positive sample, Patient 1 is positive. All of Patient 1's initial concentrations were closer to the concentration of the positive sample than the negative sample. Patient 2-19967 : Patient 2 had an average initial PCR product concentration that was 8.9712 μg/mL less than that of the product concentration of the positive sample, and 45.6288 μg/mL greater than that the product concentration of the negative sample. Since Patient 2 had a concentration closer to the concentration of the positive sample, Patient 2 is positive. All of Patient 2's initial concentrations were closer to the concentration of the positive sample than the negative sample. Positive initial concentrations suggest that the patient is positive, while negative initial concentrations suggest that the patient is negative. SNP Information & Primer Design Background: About the Disease SNP A nucleotide is the basic building block of DNA and other nucleic acids. the four main nucleotides are A,C,T,and G. A polymorphism is a common change in DNA sequences that appears in the phenotypes of different groups of population. The SNP rs16991654 variation is found in homosapiens. This variation is found in the 21:34370656 chromosome. The clinical significance is this SNP is that it is pathogenic. This SNP is associated with the KCNE2 gene. This SNP is linked to the disease of congenital long QT syndromes. KCNE2 stands for potassium voltage-gated channel, Isk-related family, member 2. The molecular function of this gene includes regulating neurotransmitter release, heart rate, insulin secretion, neuronal excitability, epithelial electrolyte transport, smooth muscle contraction, and cell volume. An allele in an alternative to a gene sequence that are done through mutation of a nucleotide base pair. The disease-associated allele contains the sequence CTC. The numerical position of the SNP is 34,370,656. The non-disease forward primer is catggtgatgattggaatgt. The numerical position exactly 200 bases to the right of the disease SNP is 3,430,856. The non-disease reverse primer is cccttatcagggggacattt. The diseases forward primer is catggtgatgattggaatgc. The disease reverse primer is cccttatcagggggacattt. Primer Design and Testing When the non-disease forward primer was tested, it was found in the database. This is because a part of the DNA that was selected did not contain the sequence that causes the disease. The disease specific primers did not exist because one nucleotide was changed in the DNA sequence. While this may cause the disease, it affects the entire sequence, it does not exist since it did not change by a group of three nucleotides, or an entire codon.
