This seems a bit counter-intuitive! Can you explain why? I'm used to thinking that genetic differences between cases and controls point to genes, which point to mechanism, but if you have genetically identical people, how does that help?If we have some gene leads established then twin studies are potentially very useful.
That's a big surprise that twins are not genetically identical! Fat lot I know about biology.Presumably because not all twins are genetically identical and for those that are it can help understand the non-genetic factors?
I’m 22 years old. I’ve been completely bedridden for almost 2 years now with MECFS. It was triggered by a stomach bug.I have a TWIN brother who had the same stomach bug a day earlier but is perfectly healthy. Any interest from researchers?
Twins come from different eggs being fertilised at the same time by different sperm, so they are not any more identical than regular siblings.That's a big surprise that twins are not genetically identical! Fat lot I know about biology.
I think most ppl think of identical when saying “twins” in conversation. I’ve always referred to the two egg as fraternal twins.Twins come from different eggs being fertilised at the same time by different sperm, so they are not any more identical than regular siblings.
Identical twins come from one fertilised egg that split into two embryos so they have nearly identical dna.
That baffles me, but I’ll take your word for itI think most ppl think of identical when saying “twins” in conversation. I’ve always referred to the two egg as fraternal twins.
Participants consisted of male identical twins, discordant for ME/CFS, as well as one extremely severe male ME/CFS patient and age-, and gender-, and BMI-matched healthy participant.
I did, that's why I was confused.That baffles me, but I’ll take your word for it
Interesting. So some people would never call a brother and sister born at the same time twins and 2 brothers and a sister born at the same time wouldn't be called triplets and people of different gender would never be called quadruplets and so forth according to the language some people use?I did, that's why I was confused.
I don't think gender comes into it - I just tend to forget about the existence of non-identical twins, and did so particularly in this context of someone offering themselves up for twin research because if they weren't identical, why would they be interesting to research any more than ordinary siblings...Interesting.

Ah ok I understand your thought process. You assumed he must be an identical twin because he assumes he's an interesting study subject. I thought you only refered to twins as being twins when they are genetically identically so I was wandering about the obvious things such a different sex twins (or more), something most people will have come across in their lives, which per definition cannot be identical.I don't think gender comes into it - I just tend to forget about the existence of non-identical twins, and did so particularly in this context of someone offering themselves up for twin research because if they weren't identical, why would they be interesting to research any more than ordinary siblings...
