>Haplogroup DE is a human Y-chromosome DNA haplogroup. It is defined by the single nucleotide polymorphism (SNP) mutations, or UEPs, M1(YAP), M145(P205), M203, P144, P153, P165, P167, P183. DE is unique because it is distributed in several geographically distinct clusters. An immediate subclade, haplogroup D (also known as D-CTS3946), is mainly found in East Asia, parts of Central Asia, and the Andaman Islands, but also sporadically in West Africa and West Asia. The other immediate subclade, haplogroup E, is common in Africa, and to a lesser extent the Middle East and southern Europe
>It is thought that the haplogroups D-M55 (D1a2a) and C1a1 were frequent among the historical Jōmon period people of Japan. One 3,800-year-old Jōmon man excavated from Rebun Island was found to belong to Haplogroup D1a2b1(D-CTS 220). Today, haplogroup D-M55 is found in about 35% and haplogroup C1a1 in about 6% of modern Japanese people. D-M55 is found regularly only in Japanese (Ainu, Ryukyuans, and Yamato) and Koreans (albeit with much lower frequency). D-M55 also has been observed in Micronesia 5.1%, Timor 0.2%, China 0–0.4%, this is explained by recent admixture, dating back to the Japanese empire (1868–1945) occupation of those regions. Haplogroup C1a1 has been found regularly in about 6% of modern Japanese. Elsewhere, it has been observed sporadically in individuals from South Korea, North Korea (South Hwanghae Province), and China (ethnic Korean in Ning'an and Han Chinese in Linghai, Guancheng Hui District, Haigang District, and Dinghai District). A 2021 study estimated that the frequency of the D-M55 clade increased during the late Jōmon period. The divergence between the D1a2-M55 and the D1a-F6251 subclades (the latter of which is common in Tibetans, other Tibeto-Burmese groups, and Altaians, and has a moderate distribution in the rest of East Asia, Southeast Asia, and Central Asia)
