Check your Lactase Persistence

@Garaad Awal on my raw data file it says RS41380347 AA what does that mean. I carry both alleles? No alleles or one allele im not sure how this works

You are right. Seems most of us in this thread don’t have the Arabian variant

Went through it and found I had rs41525747 C/G so it works atleast

"It’s common in Arabian Peninsula, North-East Africa, and parts of East Africa populations that historically practiced pastoralism." Wonder if it was spread by pastoralist Cushites into Arabia.

Yeah, seems I got the the alleles confused when I used GPT's help. 23andme uses a different system from these studies:

The T/G−13915 variant upstream of the lactase gene (LCT) is the founder allele of lactase persistence in an urban Saudi population - PMC

The prevalence of lactase persistence is high in Saudi Arabia. To identify a DNA variant for the lactase persistence/non‐persistence trait in adult Arabs in Saudi Arabia. We sequenced DNA from 432 anonymous neonatal blood donors from five different ...

A is the ancestral allele, C is the derived allele. . And it seems none of us have it.

Wallahi, it's been so long since I bothered SNP hunting. I should have checked SNPedia. Thank you, walaalkay. @Xareen your Wawat larp is back on. Granted, we still have Arabian T-L208, E-M84, J-P58 and mtDNA HV1b1 lineages that make it pretty apparent Somalis have at least some clear post-Copper Age admixture from Arabians specifically.

@Garaad Awal My bad, walaal!

Cushitic admixture across the Red Sea most likely. Plenty of Cushitic paternal & maternal lineages among the Yemenis & Hijazis.
