Disease Linkages and the Seven Daughters of Eve “DNA and Your Health” Presentation by Donald N. Yates, Ph.D.
Heterozygous disease • Sickle cell anemia and resistance to malaria • Longevity and Alzheimer’s --? • Autosomal dominant – only need one copy of gene (one parent will have full-blown disease, e.g. Huntington’s disease) • Autosomal recessive – need two copies of the disease
Review 1 • When did mitochondrial Eve live • What are mitochondria • Why does it allow tracing of lineages? • Difference between mitochondrial and autosomal disease • Difference between dominant and recessive
Before the Dawn • Before even prehistory • Homo sapiens sapiens was not alone • Homo erectus • Neanderthals • Homo florensiensis • Evolutionary theory • Nicolas Wade book
Daughters of Eve in Europe • Helena: 48% • Ursula: 19% • Jasmine: 10% • Tara: 8% • Katrina: 6% • Velda: 5% • Xenia: 2%
Jewish Ethnic Divisions • Sephardic • Ashkenazi • Khazars • Mizrahim • Romaniote • Kaifeng
The Great Migration • 1500-1789: Colonial Period • 1650-1790: 15 million Africans • 1789-1870: Western European • 1830-1850: Indians put on Western res. • 1870-1924: Eastern European • Since 1910: 7 million blacks to North • Since 1949: Jews to Israel • Hispanics in U.S., Arabs in Europe
Review 2 • Human peopling of the world • Indo-Europeans, Celts, agriculturalists • Barbarians • The Great Migration • Africans • Native Americans
Jewish Diseases • Tay-Sachs Disease • Familial Mediterranean Fever • Bloom’s Syndrome • Gaucher Disease • Machado Joseph Disease • Breast and Ovarian Cancer • Anemias • LHON
Types of Testing • Newborn • Diagnostic • Carrier • Predictive, presymptomatic • Forensic
Genetic Health Risks • Alcohol Flush Reaction • Age-related Macular Degeneration • Bitter Taste Perception • Non-ABO Blood Groups • Breast Cancer • Celiac Disease • Colorectal Cancer • Crohn's Disease
Genetic Health Risks - 2 • Earwax Type • Eye Color • G6PD Deficiency • Heart Attack • Resistance to HIV/AIDS • Lactose Intolerance • Lung Cancer • Lupus (Systemic Lupus Erythematosus) • Malaria Resistance (Duffy Antigen) • Multiple Sclerosis
Genetic Health Risks - 3 • Muscle Performance • Norovirus Resistance • Obesity • Prostate Cancer • Psoriasis • Restless Legs Syndrome • Rheumatoid Arthritis • Sickle Cell Anemia & Malaria Resistance • Type 1 Diabetes • Type 2 Diabetes • Venous Thromboembolism
Review 3 • Types of testing, screening • Types of genetic diseases • Examples of risk factors you can screen for
History of DNA Fingerprinting • 1985 PCR • 1988 FBI starts DNA casework • 1991 First paper reporting Y-STRs • 1998 FBI launches CODIS database • 2005 OmniPop population database • 2006 DNA Testing introduces DNA Fingerprint Test
Uses of CODIS Profiles • Forensic cases -- matching suspect with evidence • Paternity testing -- identifying father • Historical investigations • Missing persons investigations • Mass disasters -- putting pieces back together • Military DNA “dog tag” • Convicted felon DNA databases
DNA Fingerprint Test • Melungeons • Basis is CODIS-15 • OmniPop 360 • ENFSI • All customized and personalized Beth Hirschman
Linkage Disequilibrium for Mitochondrial Haplotypes • Helena is prone to developing Alzheimer’s • Jasmine is susceptible to passing all the Jewish diseases • Ursulas often have occipital strokes in old age
Other Linkages • Lactose intolerance: Jews, Mediterranean lineages, Asians • Graves’ Disease in Chinese Han • Sickle cell anemia: Africans and African Americans • Athletic gene: long-distance runners versus sprinters • “Intelligence gene”
Ongoing Genome-Wide Linkage Research • Diabetes • Rheumatoid arthritis • Coronary heart disease • Prostate cancer
Review 4 • CODIS markers • Alleles • DNA Fingerprint Test • OmniPop • ENFSI • Melungeons • Linkage disequilibrium
