Lineage A has the 200A-204T-16124A haplotype, lineage B the 200G-204C-16124G haplotype, and lineage C the 200G-204T-16124G haplotype (Vi33.16 reference sequence). In addition, all lineages differ from the Vi33.16 Neandertal by an A to C transversion at position 16177. Vi33.16 has the following haplotype at El Sidrón polymorphic positions: 200G,-204T-16124A.
