Did I ever ask whether they were interested in getting "donations" from family members who *don't* have ME, as a comparison?
I can't remember if you did but we aren't I'm afraid.

Excellent. That applies to all four participants: Andy, Sonya, Chris and whoever the presenter was (sorry, didn't catch his name). Well worth listening to and good for sharing with people not already deeply steeped in ME advocacy or research. :thumbup:
Oh good. Thanks for the feedback :)

I also listened last night, well done to all, and would recommend it too, as Ravn has said above.
 
I haven't had a chance to listen to this yet, so anybody who does will have to tell me how well or not I did.

I have just listened to this podcast. Thank you @Andy, Sonya and Chris. A truly excellent overview of all aspects of the situation for pwME - the need for patients to be listened to and believed, the urgent need for more and better research, the severity of ME, and the lack of belief, support and research for the last 40 years.
Andy you spoke eloquently for us all.
 
I just started listening to the webinar. I’m at the point where the discussion is about how to make sure only people with ME take part (ie not misdiagnosed people). Chris Ponting mentioned exclusion criteria. Could someone involved, expand on exactly what the criteria is to take part & what the exclusion criteria is? Thank you. I would really like to take part and have been really looking forward to it for a long time! but it suddenly occurred to me that I’m not sure if I should / would be allowed to.

We will ask you for confirmation that you have had a diagnosis of ME, CFS, ME/CFS or CFS/ME from a clinician. After confirming that, you will then need to complete a questionnaire which will assess you against the Canadian Consensus and NAM (was IOM) criteria. We hope that the vast majority of patients will be able to complete the questionnaire online but there is the option of a paper questionnaire should that be easier for you. So long as you match one of those criteria then you will be sent a spit kit.

Exclusion criteria is not having an official diagnosis, not having PEM and not matching either of the criteria. Hope that helps.

What if you used to meet the criteria but you don't anymore? (I met the criteria for several years but, whilst I am still very disabled by ME-like symptoms, no longer meet them.) (And I have a clinician diagnosis.)

Then unfortunately you wouldn't be able to take part as you wouldn't meet our inclusion criteria.

I have a question. Will the DNA looked at in this study include mitochondrial DNA?
Good question. I don't think so but I would need to check to be certain.
 
I don't really understand what that means haha, but good to know they'll be looking at it!

I tried to do some reading to understand it, maybe this helps others too?

Common genetic variants are those that are found more commonly in the general population, but which don’t usually (by themselves) cause disease.

from https://medlineplus.gov/genetics/understanding/mutationsanddisorders/genemutation/: “Most variants do not lead to development of disease, and those that do are uncommon in the general population. Some variants occur often enough in the population to be considered common genetic variation. Several such variants are responsible for differences between people such as eye color, hair color, and blood type. Although many of these common variations in the DNA have no negative effects on a person’s health, some may influence the risk of developing certain disorders.”

So if a GWAS only looks at common variants, it won’t be looking at rare variants (ie those that are found less commonly in the general population, at a “minor allele frequency” of less than 1%). I think most rare diseases which are directly attributed to a certain gene eg mitochondrial diseases that are currently known about, are caused by rare variants. So the GWAS wouldn’t be looking at the sort of variants that cause genetic mitochondrial diseases. It’s not like testing the whole genome (WGS).

However, common genetic variants can lead to increased risk of disease, and so if we find that common genetic variants pop up in the GWAS, it can help give clues as to what is contributing to the illness.

(Does this mean though, that it could potentially miss some clues to be found in rare variants?)

(If I’m wrong, please correct me!)
 
From my understanding, GWAS is done from the DNA; extracted presumably from every cells, may it be blood, epithelial cell (skin) and mucosa. Mitochondrial DNA requires an extra step of getting into the mitochondria and extracting the DNA from there. I believe that you need to extract it from mito rich tissues, such as muscles, via muscle biopsy.

I may be all wrong and confused, but i had that done and i needed a muscle biopsy.
 

Podcast Review: The Challenges Facing ME/CFS Patients and the Future of Personalised Treatments
29 November 2021
By Ara Schorscher-Petcu

Appeared in BioNews 1123

My first encounter with myalgic encephalomyelitis (ME), also known as chronic fatigue syndrome (CFS), was through my flat mate when I moved to London in 2015.

Having worked in the biomedical field for 15+ years, I had not heard about the disease before meeting Sarah (not her real name), then in her late 40s. I could not help myself but raise a doubtful brow when she first told me about her decade-long struggle with both, the disease, and the medical care (or lack thereof). The combination of symptoms, from outright exhaustion and brain fog to intricate food-intolerances seemed bewildering and skittish to me. However, witnessing one of Sarah's relapse crises, made my scepticism vanish promptly. In fact, seeing her collapse and shake, then recover her senses slowly but not being able to stand or walk by herself for hours, was scary, to say the least.

Indeed, the clinical understanding of ME/CFS is vast and at times confusing, as symptoms and disease progression vary greatly between patients. Profound fatigue and inability to cope with physical and/or mental effort are at its core. Chronic pain, recurrent infections, low mood, and cognitive impairment are also common. The causes behind the illness are equally mysterious, although a previous episode of viral or bacterial infection has been linked to at least a subset of cases. Not surprisingly, there are parallels to be drawn between ME/CFS and the emerging picture of long COVID, as they share several key symptoms.

Not only is ME/CFS a devastating disease, but patients are left painfully alone with it.

The Genetics Podcast, hosted by Dr Patrick Short, brings this message across with power and dignity. This episode has the format of a round-table with three founding members of DecodeME, a project led by Professor Chris Ponting from the University of Edinburgh. Professor Ponting's team has secured funding for the first large scale genome-wide association study (GWAS) into ME/CFS and recruited 25,000 participants to identify gene-variants linked to the disease. Sonya Chowdhury, CEO of Action for ME, and Andy Devereux-Cooke, co-founder of the Science for ME forum were the other guests from the DecodeME project.

Hi, i'm not sure if this has been covered already, but i couldn't find anything in the FAQs, so thought i'd ask here in case anyone knows. If something serious, other than ME is found on someone's sample, will they be notified of this so they can get the relevant medical treatment / preventative care, or not because there's too many subjects?

I'm not sure i'd want to know or not, on the one hand it would be good to know, but on the other hand i'm not sure i could cope with knowing anything else is wrong with my body... it's something that's always stopped me being too curious about the home genetics testing. But either way it would be good to know in advance of submitting a sample.

Thanks in advance to anyone who can answer and also to all those working hard to make this study happen!
