I2a2b L38+ - News

• all I-L38 samples had no result (mis-call) reported for SNP CTS3401;
• only one sample has a meaningfull result for SNP CTS3402;
• differences were observed at SNPs F3320 (no-call) and PF112 (mis-call) and PF3590 (mis-call for 2 samples) See the table below for more detail.

*: partial raw data results were compared (potentially these samples could harbour other mutations - the FTDNA SNP summary (cfr the project's SNP page) however shows no differences)

Terry D. Robb interpretes PF112 as a mutation. Since Holmes belongs to the I-L38 "21-9" subgroup it would be interesting to know the PF112 result of other members of this subgroup.

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).

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 positive.

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).

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: http://sites.google.com/site/haplogroupil38/i-l38-distribution-map
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.
