Analysis of L526 SNP

SUMMARY OF SNP (September, 2012)

Classification of SNP: Private or near private - son of DF13.

Estimated Breadth of SNP (speculative estimate of positive submissions) = 2 = 2 x 95 % (14 of 14) + 0 x 90 % (13 of 14) + 0 x 85 % (12 of 14) + 0 x 80 % (11 of 14) + 0 x 60 % (10 of 14) + 0 x 30 % (9 of 14) + 0 x 10 % (8 of 14) + 1 x 5 % (7 of 14). Very isolated fingerprint with only two matches above 70 % and only one transitional match between 50 and 70 %. Accuracy of the L526 fingerprint is speculative based only on two submissions that have the surname Lurz and have no mutations between the two submissions.

Scope of Testing within Fingerprint: Only Two.

Dominant Surname: Lurz (2).

Year that SNPs were discovered: July, 2012.

Source of SNP: FTDNA - WTY discovery.

Baseline for SNP: Lurz, FTDNA ID 64047, Y-Search ID 6C3CZ.

Number of Positive Tests: Only two.

Number of Negative Broad Tests: 36 (mostly WTY tests).

Number of Negative Tests within Fingerprint: None.

Possible Candidates (70 % match): None found.

Pending Tests (within Fingerprint): Not applicable (no matches found)..

 

ANALYSIS OF FINGERPRINT MARKERS

 

With such an isolated fingerprint and so few matching submissions, no analysis of fingerprint markers is really possible. Several marker values within the L526 fingerprint are multiple step mutations from the L21 modal marker value.

 

TRENDS OF TESTING CANDIDATES

Note that the number of known testing candidates do not appear to be a typical for L21 SNP where the number of testing candidates declines down to 70 % matches and then sees a sharp rise as non-L193 submissions dominate the under 50 % matches. L526 appears to be very genetically isolated within R-L21 or probably has a very poor sampling due to its origin in Romania. Since only two matching submissions are known, the fingerprint is speculative in nature due to lack of tested candidates and the lack of testing candidates to compare to.

ISOGG Status - Prove relationship of L526 to other L21 SNPs

 

Requirements for proving the position of L526 on the ISOGG haplotree have not been met and are unlikely to qualify in the near future due to the extreme genetic isolation of existing submissions and the lack of testing candidates. Most of these recommended tests will help determine the relationship between L564 and other L21 Y-SNPs.

ISOGG Status - Prove genetic and surname diversity of L526

 

L526 does not satisfy either the 15 % genetic diversity requirement or the surname diversity requirement for inclusion on the ISOGG haplotree. Two submissions of L526 must have at least a genetic distance of 10 (15 % x 67 markers = 10). It is unlikely that this Y-SNP will qualify in the near future due to lack of testing candidates.
