L362 Status (March, 2013)

This Y-SNP has tested positive for only seven submissions. Since an overlap of both positive and negative submissions has been observed at high fingerprint matches suggests significant overlap of positive and negative submissins is likely. Since the number of testing candidates remains somewhat flat with decreasing fingerprint matches, it is expected that much more overlap could be revealed with additional testing. With the L362 tracking so well with 557 >= 17, 617 >= 13 and 557 >=17, additional testing should be done with these key marker values being heavily considered as testing criteria.

1) For higher fingerprint matchs (83 % or higher), submissions should be tested that could test negative due to not matching the two key marker vaues 557 >= 17 and 617 >= 13. It is highly recommended that the following 557 = 16 and 617 = 12 submissions be tested: 55306 (Kenan) and 62298 and 55127 (Eubank). Other possible 557 = 16 only tests would be: N55690 (Crowley), 21275 (Driscoll) and 135483 (Carter). Since overlap of submissions testing positive and negative is expected with even high fingerprint matches, it is recommended that other submissions with different surnames be tested for matches 10 of 12 or higher (above 83 % fingerprint matches).

2) There are several more good testing candidates found that are between 50 % and 83 % of the L362 fingerprint. Since 557 >= 17 and 617 >= 13 are key to testing positive for L362, it is higher recommended that lower fingerprint matches with 557 >= 17 and 617 >= 13 should be tested: Short (165300) and Gilston (4R27F and FCT3N). Also, testing the only remaining 557 >= 17 should be tested: Ogan (26029).

3) Since overlap of submissions testing positive and negative is expected with even lower fingerprint matches, it is recommended that other submissions with different surnames be tested for matches between 6 of 12 through 9 of 12 (50 % to 75 %). Probably 80 % to 90 % of these submissions will test negative but those that do test positive will be critical on understanding the origin of L362.
