Haplogroup I-M253, also known as I1, is a Y chromosome haplogroup. The genetic markers confirmed as identifying I-M253 are the SNPs M253,M307.2/P203.2, M450/S109, P30, P40, L64, L75, L80, L81, L118, L121/S62, L123, L124/S64, L125/S65, L157.1, L186, and L187. It is a primary branch of Haplogroup I-M170 (I*).
The haplogroup reaches its peak frequencies in Sweden (52 percent of males in Västra Götaland County) and western Finland (more than 50 percent in Satakunta province). In terms of national averages, I-M253 is found in 35–38 per cent of Swedish males,32.8% of Danish males, about 31.5% of Norwegian males, and about 28% of Finnish males.
Haplogroup I-M253 is a primary branch of haplogroup I* (I-M170), which has been present in Europe since ancient times. The other primary branch of I* is I-M438, also known as I2.
Before a reclassification in 2008, the group was known as I1a, a name that has since been reassigned to a primary branch, haplogroup I-DF29. The other primary branches of I1 (M253) are I1b (S249/Z131) and I1c (Y18119/Z17925).
