I2a2b L38+ - News

21st of February 2014

Britains DNA published the results of their Chromo2 dataset https://www.britainsdna.com/download/C2_2000.zip.

Of the 2000 samples, 14 belong to haplogroup I-L38 which they call it I-S155 (this is another name for L39). So 0.7% of the Brits belong to I-L38.

Among the 14.200 SNPs the following 15 (S-series) mutations appeared in the I-L38 group:

S10269; S11558; S12480; S12547; S15855; S19763; S21118; S22679; S24121; S24647; S2488; S25490; S2606; S27697; S4556

The 14 I-L38 samples are all L69 (aka S163) and L533 (aka S295) negative, so we are taking about new subclades.

I-L38 project member Stephen Prata published a very interesting study on I-L38 network relations at https://sites.google.com/site/haplogroupil38/median-networks

February 2014
This far 13 members of the FTDNA I-L38 project shared their SNP results of the National Genographic's Geno 2.0 project to our project. Most of them shared their raw data file for comparision. More results of I-L38 Geno 2.0 participants should be compared to find out more about the structure of haplogroup I-L38.

This far the comparision of the more than 12.000 Ydna-SNPs can be summarized as follows:

SNP Prata Leblans Holmes Te Raa Rowland Deterding Sutherland Attwood Hammond Suarez Odom McKinney Knezevic
L533 G,G G,G G,G G,G G,G G,G G,G   G,G G,G C,C G,G G,G

PF3590 T,C T,T T,T T,T T,T T,C T,T T,T T,T T,T T,T T,T T,C

L69: this SNP is not included in Geno 2.0, the results that are shown come from 23andme

F780: One of the FTDNA I-L38 project members (Deterding/confirmed L38) took the Geno2.0 test. His paternal line is typed by the Genographic project as I-F780. Deterding had A,G for SNP F780. All other I-L38 members with known F780 23andme results tested G,G on this SNP. SNP F780 probably indicates the third branch of I-L38.

CTS3402: some I-L38 BigY samples display an ancestral "A"-value for this SNP, making the "G" result of Te Raa definatelly a new branch of I-L38

Less likely suspects:

CTS3401: are these I-L38 specific no-calls? Deletion?

PF112: Holmes, belonging to the I-L38 "21-9" subgroup, reported a miscall (A,T) for PF112. Other members of this subgroup tested PF112-. National Geographic does not interprete PF112 as a mutation since they describe the paternal haplogroup of Holmes as I-L38 and not as I-PF112.

PF3590: Ken Nordtvedt does not interprete PF3590 as a mutation because he thinks the mis-reading is due to a calibration change between the 12316 ysnps reports from Geno2 and the later 12062 ysnps reports.  All haplogroup I customers got the same result (T,C) in the first batch of results, and all those in later batch got the same different result (T,T).

PF3514: Probably Geno 2.0 has recalibrated/fixed PF3514 recently. Bernie Cullen has multiple PF3514=A,A in I-P37.2 since November, before that they were almost all A G.

In her book "Ancestral Journeys - the peopling of Europe from the first venturers to the Vikings" (Thames & Hudson, 2013, p.149) Jean Manco relates haplogroup I-L460 (from which I-L38 is a branch) to the Neolithic Usatovo culture and the villages around the Dniester. According Manco this relation explains why I-L38 appears alongside R1a(11) after apparently migrating up the Dniester and around the Carpathians into present-day Germany.

August 2013

The 23andme results of two I-L38 project members: Prata and Marotta (both belonging to the "22-14" cluster), show that they share the same L69/S163/rs9786274 = T,T mutation. It seems that SNP L69 (after L533) determines the second branch of I-L38.

At the YDNA SNPS Comparison Project (on Facebook: https://www.facebook.com/pages/YDNA-SNPs-Comparison-Project/166307390055000) the (23andme) SNPs of 10 I-L38 samples can be found. One of these samples, named Marotta, tested  L69/S163/rs9786274  positive. 

Pilgrim Captain Myles Standish (

July 2012
During the years 2005 and 2006 approximately 2000 archaeological finds ranging from the Neolithic Period to Late Antiquity were found on the Kletthamer Feld (Erding, Upper Bavaria). Out of this context a burial site was examined comprising 13 individuals, some of them rich in precious grave goods. The inhumations were dated to the second half of the 4th to the first half of the 5th century – a time of upheavals in relation to the demographic structure of the former Roman province Raetia (today southern Bavaria).
Inserting the 9 displayed STR values of samples 1664 and 1704 in Cullen's Haplogroup I Predictor, leads to the following haplogroup estimations: Ix-S23 =>25%  I-S24 =>25%    J2-M102 =>22%  I-S31* =>14%  I-M253 =>9%  I-P37.2 =>3%  G , G2 =>2%
Ix-S23 is the name Cullen's predictor uses for I-L38. Although the DYS393 (=16) value of the samples 1664 and 1704 is very atypical for I-L38, it might be possible that these samples belong to haplogroup I-L38 (which would not be that surprising since Bavaria is not that far from the Upper Rhine region).

May 2012

In february 2012 Terry D. Robb presented frequency maps for several I2 haplogroups, among them “I2.0110*” (which is his code name for I-L38).
According to Terry, France and Switzerland come out the dominant (highest frequency) places. But also England, and even Norway, still have a significant frequency of I-L38.
This frequency map differs from the frequency map made by Hans De Beule in 2010:
According to Hans, I-L38 mainly spread in an area that can be described as a diagonal “belt” going from the NW of Europe to the SE. In his view, the highest concentrations (and STR diversity) are to be found in the Upper and Middle Rhine area.
Terry agrees that finer geographic binning will conclude that certain parts of France have higher frequencies than others. Also on Hans’ map France, (and especially the NE) has a significant I-L38 frequency.
Overall conclusion is that more (and especially French) samples are needed to finetune the current frequency maps.

May 2012
In 2012 it became clear that SNP L533 separates I-L38 in a modest way. Until now only few I-L38 families turned out to be L533 positive. Members with DYS385a,b=13, 14 AND DYS454=11 are encouraged to test for L533 since this combination looks like the "STR-signature" of I-L533.

March 2009

So far for the results returned for L38,L39, and L40 there has been no separation with members testing positive for all three SNP's.
