Tracing the start of COVID-19 in GA

At a time when COVID-19 appears to be receding in much of Georgia, it’s worth revisiting the start of the pandemic in early 2020. Emory virologist Anne Piantadosi and colleagues have a paper in Viral Evolution on the earliest SARS-CoV-2 genetic sequences detected in Georgia. Analyzing relationships between those virus sequences and samples from other states and countries can give us an idea about where the first COVID-19 infections in Georgia came from. We can draw Read more

Reddit as window into opioid withdrawal strategies

Drug abuse researchers are using the social media site Reddit as a window into the experiences of people living with opioid addiction. Abeed Sarker in Emory's Department of Biomedical Informatics has a paper in Clinical Toxicology focusing on the phenomenon of “precipitated withdrawal,” in collaboration with emergency medicine specialists from Penn, Rutgers and Mt Sinai. Precipitated withdrawal is a more intense form of withdrawal that can occur when someone who was using opioids starts medication-assisted treatment Read more

CROI: HIV cure report and ongoing research

The big news out of CROI (Conference on Retroviruses and Opportunistic Infections) was a report of a third person being cured of HIV infection, this time using umbilical cord blood for a hematopoetic stem cell transplant. Emory’s Carlos del Rio gave a nice overview of the achievement for NPR this morning. As del Rio explains, the field of HIV cure research took off over the last decade after Timothy Brown, known as “the Berlin patient,” Read more

Four take-home thoughts on NGLY1

Please check out our feature in Emory Medicine magazine about two sisters with NGLY1 deficiency. This rare genetic disorder was identified only a few years ago, and now a surge of research is directed toward uncovering its mysteries.

  1. The Stinchcombs are amazing. Seth Mnookin’s July 2014 piece in the New Yorker, and especially, his comments at the end of an interview with The Open Notebook drove me to contact them. “The father cares for the two girls with this disease full time. The mother is working insane hours. And while all this is going on, they’re the most good-natured … I don’t know, they just seem like they’re happy.”
  1. Several research teams around the world are investigating NGLY1 deficiency and potential remedies. For the magazine article, I talked with Emory geneticist Michael Gambello, Hudson Freeze at Sanford Burnham and Lynne Wolfe at the NIH Undiagnosed Diseases Program. Even more: the Grace Science Foundation, established by the Wilsey family, is supporting research at Retrophin/Notre Dame and Gladstone/UCSF. The independent Perlstein lab is investigating NGLY1 deficiency in fruit flies (reminiscent of Emory research from a decade ago on Fragile X syndrome).
  1. There’s a long road ahead for rare genetic disorders such as NGLY1 deficiency. That’s why the title that EM editor Mary Loftus came up with, “In time to help Jessie,” is so poignant. When I read Abby Goodnough’s New York Times piece on RCDP, which is a rare inherited bone disease that also involves seizures, I thought: “That could be NGLY1 in ten years.” Still, progress is possible, as demonstrated by this recent NEJM report on exome sequencing and neurometabolic disorders from British Columbia.
