I have wondered if there is a genetic component to RLS, meaning is it commonly found in certain genetic groups of people- not just in families? (Some other health issues are - like Sickle Cell anemia more common in people of African descent, or Cystic Fibrosis in Caucasians. Even things like being lactose intolerant or having the second toe longer than the big toe can be common among genetic groups of people.
The reason I wonder is that this website is from Britain and by far many people on here live there. There have been some Aussies, and Irish, and from the US, which has quite a few people of similar descents. I myself am half English/Irish/Scottish, and the other half is Bohemian/German.
We did have on here for awhile someone who was Chinese, born and raised, she told me, in China Town in Chicago. (I am from Chicago and live just south of the city myself.)
So, of the genetic type of RLS, (not that caused by spinal injury, etc.,) is this more common among Caucasians? Is it more common among those of British descent, altho I know that English, Scottish and Irish have Roman, Viking, Norman, Saxon blood etc., besides the indigenous peoples (the Celts, the Picts, etc.)
Are we just seeing these types of people on here because it is a British site? Do other groups of people also have RLS? Did they have it so much in the past, or is it more of a modern disease or at least made worse by many of the chemicals and pseudo foods in our environment?
Not that knowing these things changes anything particularly. If one has it then one must deal with it. I just wonder because that is how my mind works. I like to (armchair) study history, prehistory, genetics, etc. and so I think about these things.
I just found out that I am 4% Neanderthal (My sister had her DNA done.) Did Neanderthals get RLS? (!!??)
So, just a little aside one can think about and ponder.
