SUMMARY OF SNP

Classification of SNP: Private.

Estimated Breadth of SNP: 4 to 10 submissions.

Scope of Testing within Fingerprint: (December, 2011) - Above Average - Two tested out of four possible candidates (over 70 % match of DNA fingerprint).

Dominant Surnames (positive): McKenzie (1).

Year that SNPs were discovered: 2010 (estimate).

Source of SNP: FTDNA WTY - McKenzie (150594 & KJP3F).

Number of Positive Tests (December, 2011): Only one known.

Number of Negative Broad Tests (December, 2011): 25 tested (R-L21 project).

Number of Negative Tests within Fingerprint (70 %): One.

Possible Candidates (70 % match): Around 4.

Pending Tests (within Fingerprint): None known.

DNA FINGERPRINTS

L21 Off Modal Mutations:

Markers 1 to 37: 390 <= 23, 459b <= 9, 448 <= 18, 449 <= 29 and 464d >= 18 (5 mutations).

Markers 38 to 67: 406S1 >= 11, 413a <= 22 and 617 >= 13 (3 mutations).

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

None known - only WTY submission found positive.

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

FP (6 of 8 match) and GD = 5, Cameron (37986 and WGGSQ).

DNA Signature (Walsh): 513-1113-E.

Markers 1 to 37: 448 = 18 and 464d = 18 (2 mutations).

Markers 38 to 67: 406S1 >= 11 and 617 >= 13 (2 mutations).

Note: There are four good testing candidates that have not been tested (above 70 % match). Any lower odds candidates (50 to 70 % fingerprint match) would be more speculative since no positive submisisons have been tested at lower than than a 70 % DNA fingerprint match.
