Once More Into the Breach with FamilyTree DNA – May 22, 2020

I was poking around FamilyTree DNA (FTDNA), looking for a specific DNA test. It’s the CCR5 autosomal test. The test is only $39.00 USD so not that expensive. Here’s the blurb from FTDNA about it: https://learn.familytreedna.com/test-types/ccr5-test-genealogical-test/

Among the many advances and discoveries of modern DNA and genetics are ‘scientific’ oddities. These genetic wonders make it into popular culture and develop a life there that far outpaces their academic worth. These factoids are best used as ‘cocktail conversation’ starters. We present them to our current customers (those who have already ordered a standard test) as just that.


The Black Death Plague Mutation

CCR5 is a gene on chromosome 3. Our CCR5 test is for a 32 base deletion (delta 32) that has been speculatively linked to survival during the Black Death and the Small Pox Plagues (Galvani 2003) that decimated the population of Europe during the Middle Ages.

The delta 32 mutation is found in between 5% and 14% of Europeans and is rare in Asians and Africans (Sabeti 2005). Plague theories are belied by its discovery in a Bronze Age gravesite (Hummel 2005).

Remember: Results are not intended to diagnose disease or medical conditions, and they do not serve the purpose of medical advice. They are offered exclusively for curiosity purposes, i.e., to see how your results compare with what the scientific papers say. Other genetic and environmental variables may also impact these same physiological characteristics. They are merely a conversational piece or a “cocktail party” test, as we like to call it.

Decades ago, I received three vaccinations for Small Pox over whatever the standard time period between vaccinations for the same vaccination. I did not have the standard reaction to any of the Small Pox vaccinations. The doctor told me that meant I was immune to Small Pox. Don’t know if what he said was true, but he said it with conviction so he believed it. I ordered the above test to see what it shows for me and that was before I realized there was a correlation between Small Pox and Bubonic Plague or HIV.

In doing some additional research after ordering the test, I came across a clearer understanding – https://www.sciencedaily.com/releases/2003/11/031120074728.htm. The article makes a claim HIV and Small Pox have more in common than Small Pox and Bubonic Plague if I am understanding it correctly.
