AGS Patient Registry Virtual Walkthrough, Enrolling and Participating

Join the AGSAA’s Research Director Patrick Winters for a hands-on virtual walkthrough of the AGS Patient Registry.

We'll be holding 3 online meetings to accommodate different time zones around the globe on Saturday, August 6th. Patrick will host to help you enroll and participate in the registry or to answer questions like "why is this important?" and "how do you protect my privacy?" See the available times and meeting details on our AGSAA FB events page.

In advance of the virtual event, please watch our walkthrough video. Translated subtitles provided.


Introducing AGSAA Grant Awardee, Dr. Jessica Garau

Dr. Jessica Garau is a postdoctoral researcher at IRCCS Mondino Foundation in Pavia, Italy. She has been working on Aicardi-Goutières Syndrome since 2015, first as an undergraduate and then as a PhD student. After obtaining a PhD in Biomedical Sciences in 2020, Dr Garau is now a researcher committed to genetic and molecular characterization of rare genetic neurological diseases.

Dr. Jessica Garau discussed her work with AGS.

Dr. Garau will spend the second half of 2022 exploring potential causes of the high degree of variability in AGS as awardee of our Rare Researcher ECR Grant (project title and summary provided below). Many families are aware that AGS can present with varying degrees of severity and symptoms, even between siblings that share the same AGS causing mutations. Using AGS patient samples and data already available at the Mondino Foundation, Dr. Garau will take a careful look at the genomes and gene expression profiles of AGS individuals that share identical RNASEH2B mutations in an effort to pinpoint additional genes or variations that contribute to the development of mild vs severe outcomes. Regardless of her findings, this important work will provide insights into the factors that give rise to AGS and help guide our efforts to anticipate needs and identify targets for new therapies. The AGSAA will hold an event towards the end of 2022, inviting Dr. Garau and our community to discuss her project and work. We wish her good luck and good science!


Transcriptome and Exome analysis of RNASEH2B patients with heterogeneous phenotypes

PI Name: Dr. Jessica Garau, PhD

Abstract/Summary of Project

Aicardi-Goutières syndrome (AGS) is a rare early-onset genetic neuroinflammatory disorder following recessive or dominant inheritance. AGS patients exhibit symptoms including acquired or congenital microcephaly, cerebral calcification, white matter abnormalities, and cerebral atrophy from birth or develop them within their first year of life. To date, mutations in nine genes have been discovered as pathogenic, all of which encode for proteins involved in nucleic acid-sensing and/or metabolism. AGS- associated mutations in these genes result in an accumulation of endogenous DNA, RNA:DNA hybrids, and/or double-stranded RNA (dsRNA) that are recognized as “foreign” and trigger type I interferon- mediated immune responses, analogous to anti-viral responses and led to classification as “primary type I interferonopathies”. Though defined by identical disease-causing mutations, clinical presentations of AGS patients can vary significantly, even within families. Thus, additional modifying molecular pathomechanisms are likely, including the coexistence of additional genomic variants or altered expression of coding and non-coding RNAs. However, scientific evidence for these hypotheses is currently lacking. In the study proposed, we aim to define molecular modifiers of disease in AGS patients with the p.A177T mutation in RNASEH2B, the most common variant seen in our group, but with different phenotypes (mild and severe). Molecular targets include: 1) Analysis of coding and non-coding RNAs by RNA-Seq or RT-qPCR 2) Analysis of patients’ exomes to identify possible digenic variants

AGS Patient Registry Introduction and Perspective

An introduction to the AGS patient Registry (https://agsaa.org/ags-patient-registry) by the AGSAA's Research Director, Patrick Winters.


Transcription:

Hi, everyone. I wanted to introduce myself and take a moment to give you some perspective on the AGS patient registry managed by the Aicardi Goutieres Syndrome Advocacy Association (the AGSAA). My name is Patrick, and I've taken on the responsibility of research director at the AGSAA. I'm a father of three children, the youngest of which has been impacted significantly by AGS. From the very beginning of this journey, I've dedicated myself to understanding this disease and working towards solutions to improve my daughter's care. I've recently taken the lead in communications and collaborations with scientists and clinicians working on AGS. And, one of the most important and compelling things we can offer potential collaborators is coordinated access to patients, data, samples, et cetera. This registry represents and reflects our rare disease community's level of organization. A scientist looking to research a disorder or a drug company evaluating the cost of pursuing treatments for a disease will consider this in their decisions. Over the next year I've volunteered to serve as co-chair for the Global Leukodystrophy Initiative's Coalition of Patient Advocacy Groups. In my involvement with GLIA, the National Institute of Health in the U.S. , and the Rare Disease Clinical Research Network, I'll be working to help other rare disease groups prepare themselves for clinical trials by establishing registries, just like ours.

The establishment of a patient registry is the number one recommendation made by these institutions. It's the most important thing advocacy groups can do to prepare for the development of future clinical trials. Since we launched the registry, we've tried to focus surveys on data and topics that would allow us to provide useful information to families quickly and directly. By doing so, we've hoped to build a group of engaged and active participants, a necessary precursor to attracting scientists for more in depth research.

Still, I believe there's compelling work and novel insights that we can publish directly. For example, our triggers and flare survey, which is open now, will allow us to publish a full and detailed characterization of AGS disease flares. And, this is something that isn't currently written about nor well understood by families or their doctors. I'd also like to comment on data and access and visibility. None of us. And I mean it, none of us have the ability to view your name, email address, or any other personally identifiable information. Luna, the software service we use, ensures that our registry remains anonymous to us and to every collaborator that we may invite to analyze the data. All of this puts our registry above board, making it compelling to a researcher that would be able to include registry information directly in their publications.

Our registry is official in that sense, it's considered reliable; and with it we're going to advance understanding and care for AGS. So we invite all families around the world to participate. Although we acknowledge that there will be some friction and shortcomings at times, we are still dedicated to making this an inclusive and comprehensive tool for our community.

I encourage and implore you to participate.

AGS Researchers Are Not So Rare!

The AGSAA is thrilled to announce the awardees of our community funded early career researcher grant. We’ve decided to fund projects by Dr. Jessica Garau (a postdoctoral researcher at IRCCS Mondino Foundation, Pavia, Italy) and Dr. Barney Viengkhou (a postdoctoral fellow at the University of Sydney, Australia). Both projects will explore aspects of AGS and disease development that are critical to better understanding and solving this complex disorder.
