Haplogroup CF, also known as CF-P143 and CT(xDE), is a
human Y-chromosome DNA haplogroup
In human genetics, a human Y-chromosome DNA haplogroup is a haplogroup defined by specific mutations in the non-Genetic recombination, recombining portions of DNA on the male-specific Y chromosome (Y-DNA). Individuals within a haplogroup share ...

SNP P143, and its existence and distribution are inferred from the fact that haplogroups descended from CF include most human male lineages in

There are, as yet, no confirmed cases of living individuals or human remains belonging to the
basal, undivergent haplogroup CF*. In the year 2017, C-M217 (C2) & C-M130 were reported among males belonging to the

central-east Burma (as well as neighboring parts of China, Laos and Thailand). However, the researchers involved (Brunelli et al.) did not rule out all other subclades of CF, such as haplogroup
F, in these particular cases. (In haplogroup
F2 has previously been identified in the same geographical region.
