SUMMARY OF SNP

Classification of SNP: Near Private.

Estimated Breadth of SNP: 10 to 20 submissions.

Scope of Testing within Fingerprint: (January, 2012) - Above average - Four tested within 14 possible candidates (within 70 % of fingerprint).

Dominant Surnames (positive): Lewis (2), Daniel (1) and Foerstner (1).

Year that SNPs were discovered: 2010 (estimate).

Source of SNP: FTDNA - WTY - FTDNA ID 9875 and Y-Search 5ZDMH.

Number of Positive Tests (October, 2011): Four known.

Number of Negative Broad Tests (October, 2011): Only 10.

Number of Negative Tests within Fingerprint: Lewis (1).

Possible Candidates (70 % match): Around 10.

Pending Tests (within Fingerprint): None known.

DNA FINGERPRINTS

L21 Off Modal Mutations:

Markers 1 to 37: 390 >=25, 19 >= 15, 439 >= 13, 389-II >= 30, 458 >= 18, 449 <= 29, YCAIIa >=23, 456 <= 15, 576 >= 19 and 570 >= 18 (10 mutations).

Markers 38 to 67: None (0 mutations).

Most Distant Positive Test Known (67 markers)
(from MRCA of positive submissions - not WTY):

Lewis, FTDNA ID 43525, Y-Search 59R8P, 10 of 10 fingerprint match and GD=4.

Closest Negative Test Known (67 markers)
(from MRCA of positive submissions - not WTY):

Lewis, FTNDA ID 203844, Y-Search (not uploaded), 7 of 10 fingerprint match and GD=11.

DNA Signature (Walsh): 2323.

Markers 1 to 37: 390 = 25, 19 = 15, 439 = 13, 389ii-i = 17, 458 = 18 and YCAII = 23,23 (7 mutations).

Markers 38 to 67: None (0 mutations).

Note: This is a fairly new researched Y-SNP that is near private Y-SNP. There are several very good testing candidates that still have not been tested. There are many other lower odds testing candidates between 50 to 70 % match of the DNA fingerprint. With one Lewis submission testing negative at a 70 % fingerprint match, L564 may be less broad than other Y-SNPs and makes under 70 % fingerprint testing more speculative.
