R-L20 
L20 S144 rs7067305
 Found in haplogroup R1b under U152 on ISOGG, YFull, and FTDNA trees. hg38 Ref does not match ancestral allele value. Example is ancient DNA sample VK373 from 11th century Viking grave in Galgedil, Denmark. Note that an L20 lineage was one of the three samples used to compose the hg19 and hg38 human reference sequences.
DNA lineage L20 is estimated to have originated in about the year 2,680 bce based on its position in the phylogenetic tree.
