Haplogroup I-M253 is present in all populations, with higher frequencies in the east and lower frequencies in the west. There appears to be no discrete boundary as observed by Weale et al. (2002) In 2003 a paper was published by Christian Capelli and colleagues which supported, but modified, the conclusions of Weale and colleagues. [ 60 ]
Three Y chromosome haplogroups dominate the distribution among the Sami: N1c (formerly N3a), I1 – today more commonly known as I-M253 – and R1a, at least in the study carried out by K. Tambets et al. in 2004. The most common haplogroup among the Sami is N1c, with I1 as a close second according to that study.
Haplogroup I is a human mitochondrial DNA (mtDNA) haplogroup. It is believed to have originated about 21,000 years ago, during the Last Glacial Maximum (LGM) period in West Asia ( (Olivieri 2013); Terreros 2011; Fernandes 2012). The haplogroup is unusual in that it is now widely distributed geographically, but is common in only a few small ...
Good syndrome. Thymoma with immunodeficiency (also known as "Good syndrome") is a rare disorder that occurs in adults in whom hypogammaglobulinemia, deficient cell-mediated immunity, and thymoma (usually benign) may develop almost simultaneously. [1]: 82 [2] Most reported cases are in Europe, though it occurs globally. [3]
Haplogroup I-M253 (I1) at 4,3% of which L22, Z58 and Z63. According to a study published in 2010, I-M253 originated between 3,170 and 5,000 years ago, in Chalcolithic Europe. [44] A 2014 study in Hungary uncovered remains of two individuals from the Linear Pottery culture, one of whom was found to have carried the M253 SNP which defines ...
v. t. e. A haplotype is a group of alleles in an organism that are inherited together from a single parent, [1][2] and a haplogroup (haploid from the Greek: ἁπλοῦς, haploûs, "onefold, simple" and English: group) is a group of similar haplotypes that share a common ancestor with a single-nucleotide polymorphism mutation. [3]
Haplogroup I (M170) is a Y-chromosome DNA haplogroup. It is a subgroup of haplogroup IJ, which itself is a derivative of the haplogroup IJK. Subclades I1 and I2 can be found in most present-day European populations, with peaks in some Northern European and Southeastern European countries. Haplogroup I most likely arose in Europe, [1][2] with it ...
The 111 tested Y-chromosome markers (e.g. DYS391 = 10; DYS392 = 11; DYS393 = 10; DYS426 = 11; DYS447 = 23; DYS454 = 11; DYS455 = 8; YCA-IIa,b = 19, 21) from known descendants of Edmund are consistent with Haplogroup I-M253; this is an exceedingly rare haplogroup among the Welsh but is relatively common among inhabitants of East Anglia.
