Genetic Predisposition of Atherosclerotic Cardiovascular Disease in Ancient Human Remains
Abstract
Background: Several computed tomographic studies have shown the presence of atherosclerosis in ancient human remains. However, while it is important to understand the development of atherosclerotic cardiovascular disease (ASCVD), genetic data concerning the prevalence of the disease-associated single nucleotide polymorphisms (SNPs) in our ancestors are scarce.
Objective: For a better understanding of the role of genetics in the evolution of ASCVD, we applied an enrichment capture sequencing approach to mummified human remains from different geographic regions and time periods.
Methods: Twenty-two mummified individuals were analyzed for their genetic predisposition of ASCVD. Next-generation sequencing methods were applied to ancient DNA (aDNA) samples, including a novel enrichment approach specifically designed to capture SNPs associated with ASCVD in genome-wide association studies of modern humans.
Findings: Five out of 22 ancient individuals passed all filter steps for calculating a weighted polygenic risk score (PRS) based on 87 SNPs in 56 genes. PRSs were correlated to scores obtained from contemporary people from around the world and cover their complete range. The genetic results of the ancient individuals reflect their phenotypic results, given that the only two mummies showing calcified atherosclerotic arterial plaques on computed tomography scans are the ones exhibiting the highest calculated PRSs.
Conclusions: These data show that alleles associated with ASCVD have been widespread for at least 5,000 years. Despite some limitations due to the nature of aDNA, our approach has the potential to lead to a better understanding of the interaction between environmental and genetic influences on the development of ASCVD.

But it's difficult to extract any useful autosomal SNPs, most likely because the capture process targeted only some specific SNPs associated with atherosclerotic cardiovascular disease (ASCVD)

Most of the Y-chr results of the Egyptian mummies are under R1b (which is questionable)

They used shotgun as well.

Old Kingdom Egyptian samples are mostly E-M35 according to reliable leaks both from eurogenes blog/athrogenica the same guy who leaked Etruscans were mostly R1b.

Aligning them now, will send to Davidski no later than tomorrow. Many are very low quality so keep expectations in check

Possibly, are they female?

Apparently they're contaminated European samples?

Thanks for the laughs:

Yes, they are useless. I've posted them somewhere else.
Clearly contaminated, GEDmatch implied so as well.
