“Most kids say they love their mom and dad equally, but there are times when even the best prefers one parent over the other. The same can be said for how the body’s cells treat our DNA instructions. It has long been thought that each copy – one inherited from mom and one from dad – is treated the same. A new study from scientists at the University of Utah School of Medicine shows that it is not uncommon for cells in the brain to preferentially activate one copy over the other. The finding breaks basic tenants of classic genetics and suggests new ways in which genetic mutations might cause brain disorders. ”
““Even 50,000 years after the last human-Neanderthal mating, we can still see measurable impacts on gene expression,” says geneticist and study co-author Joshua Akey of the University of Washington School of Medicine. “And those variations in gene expression contribute to human phenotypic variation and disease susceptibility.””
“The sensory thalamus, a small structure located between the brain stem and the cortex, is an important gateway to the brain. Sensory information-what we see, hear, taste or feel-first passes through the thalamus before being processed in higher brain areas and the sensory thalamus was long thought to be the brain’s relay station.”
“For many years, it was believed that a single wave of ancient immigrants made their way from Asia to North America and eventually to South America—the first people to exist in the New World. But that view has been challenged in more recent years. In this new effort, the researchers describe evidence they have found that suggests the first settlers of the New World may have come from more than one place.”
“SALT LAKE CITY — DNA research and its application in family history is changing family history, said CeCe Moore, a genetic genealogist who runs DNA Detectives, at the RootsTech family history and technology conference on Saturday at the Salt Palace.
“Our genealogy is truly coming alive through our DNA,” Moore said. “Genetic genealogy is turning traditional genealogy upside down.””
“”As a part of the clinical evaluation of young patients with a variety of developmental issues, we performed clinical genomic studies and analyzed the genetic material of more than 60,000 individuals. Most of the samples were analyzed at Baylor Genetics laboratories,” said lead author Dr. Pengfei Liu”
