The two diseases we decided to analyze are Alzheimer's and Anencephaly. Alzheimer's disease is a form of dementia that affects the brain by gradually deteriorating an individual's brain function, leading to memory loss and impairing cognitive skills. The gene responsible for Alzheimer's is labeled PSEN1 and a mutation in this gene can cause toxic protein to build up in the brain leading to symptoms described above. The gene is found on chromosome 14 and the reference number for this gene is rs63751320. The allele sequence is GCTCATCTTGGCTGTGATTTCAGTAT[A/C]TGGTAAAACCCAAGACTGATAATTT. For more information on this gene can be found on this link.

Anencephaly is a relatively common neural tube defect that occurs during early fetal development; it causes parts of the brain and skull to not develop and results in fetal mortality in almost all cases. Although most occurrences of anencephaly are attributed to environmental toxins or low folic acid intake during pregnancy [http://www.ncbi.nlm.nih.gov/pubmedhealth/PMH0002547/], but has also been affiliated with Meckel syndrome, a rare genetic disorder that affects the RPGRIP1L gene [http://omim.org/entry/610937#0006]. The most severe phenotypes of Meckel syndrome are present with complete inactivation of the RPGRIP1L gene. | |||

Alzheimer- Alleles: [A/C] Forward Primer:5'CGTGGCTCATCTTGGCTGTGATTT3' Reverse Primer:3'CCCGACACTAACCTCGTCTAACAC5' The disease allele, in this case C, will give a PCR product because the PCR detects the specific allele difference or mutation and gives a positive reading. Since the PCR detects the specific allele mutation, a non-disease allele will not produce a product.
