The ‘Christchurch mutation’: How good can overpower evil in the genetic determination of Alzheimer’s disease
by Gladstone Institutes New research, led by a Gladstone team including Maxine Nelson (left) and Yadong Huang (right), sheds light on protective mechanisms of the “Christchurch mutation.” Credit: Michael Short/Gladstone Institutes (2023) Researchers at Gladstone Institutes have discovered that a rare genetic variant known as the “Christchurch mutation” can block detrimental effects of apolipoprotein E4, the...
Duchenne Muscular Dystrophy Gene Therapy Safe, Effective at 4 Years
Nancy A. Melville November 06, 2023 PHOENIX — Children with Duchenne muscular dystrophy (DMD) treated with the only gene therapy to date to be approved for treatment of disease in the United States show sustained maintenance of motor function after 4 years, compared with untreated patients who showed significant decline over the same time period, new research...
187 new genetic variants linked to prostate cancer found in largest, most diverse study of its kind
by Keck School of Medicine of USC Credit: CC0 Public Domain A globe-spanning scientific team has compiled the most comprehensive list of genetic variants associated with prostate cancer risk—451 in all—through a whole-genome analysis that ranks as the largest and most diverse investigation into prostate cancer genetics yet. The research, led by the USC Center for...
Previous genetic association studies involving people with European ancestry may be inaccurate
by NIH/National Human Genome Research Institute Researchers have found that previous studies analyzing the genomes of people with European ancestry may have reported inaccurate results by not fully accounting for population structure.

Attacking the roots of pancreatic cancer
by Alan Dove, Columbia University Irving Medical Center The new model provides a unique opportunity to understand how adenosquamous tumors, which are essentially unresponsive to current treatments, arise in the pancreas. In the new study, the researchers found that Hmmr gene activity is important for the growth of ASCP tumors and could be a new therapeutic...
Envisioning a new era: Complete genetic information from routine, telomere-to-telomere genomes
Karen H. Miga Evan E. Eichler DOI:https://doi.org/10.1016/j.ajhg.2023.09.011 SummaryAdvances in long-read sequencing and assembly now mean that individual labs can generate phased genomes that are more accurate and more contiguous than the original human reference genome. With declining costs and increasing democratization of technology, we suggest that complete genome assemblies, where both parental haplotypes are phased...
