The DYS464X (Extended) Test
The original report can be found at the following link. I is copied here for your convenience.
Definition of DYS464X
DYS464X is a special method of testing the DYS464 STR alleles. R1b males have a G/C SNP in some of their DYS464 flanking regions very close to the reverse primer of the DYS464 locus. The DYS464X test uses altered primer sequences that end with their last base exactly at the SNP. One primer ends with a "G", while the other primer ends with a "C". These primers allow us to test the different SNP variants and their corresponding DYS464 STR alleles separately.
If the primer ending with G yields a peak, the allele is classed as a G-type.
If the primer ending with C yields a peak, the allele is classed as a C-type.
FAM-ttacgagctttgggctatg (exactly from the Redd paper)
JOE-cctgggtaacagagagactctttcag (ending with G)
TMR-cctgggtaacagagagactctttcac (ending with C)
PCR parameters: 30 x (90°, 65°, 70°) and 60° end-elongation 1/2 h
Peaks with a green fluorescence (JOE) are called G type.
Peaks with a yellow fluorescence (TMR) are called C type.
There are some sample electropherograms in my library:
If you want to see a sequence alignment of the DYS464 DNA sequences and the primers you can download a BioEdit file from my alignment library:

What is the use of the DYS464X test?
Most R1b males that we have tested show 3 C-types and 1 G-type.
All other haplogroups (including R1a) show 4 G-types.
The DYS464X method can verify, if a person is really R1b
In many cases we can determine, if a single large peak really represents two different alleles
Some DYS464 patterns look similar when the conventional test is used, but really consist of completely different alleles. For example:
DYS464X is a method that helps us observe recombinational loss of heterozygosity (recLOH)
Some DYS464 examples from an arbitary surname project:
surname A, 1: 15-15-16-17
surname A, 2: 15-15-16-17
surname A, 3: 15-15-16-17
surname B, 1: 15-15-16-18
surname C, 1: 15-15-15-17
If all the 5 persons are R1b then they can be typed with an extended DYS464 test.
We might get the following results:
surname A, 1: 15c-15c-16g-17c
surname A, 2: 15c-15c-16g-17c
surname A, 3: 15c-15c-16c-17g
surname B, 1: 15c-15c-16g-18c
surname C, 1: 15c-15c-15g-17c
From that result we could say:
- A1 and A2 match completely
- A3 has at least a genetic distance of 2 from (A1 & A2)
- B1 has a genetic distance of 1 from (A1 & A2)
- C1 has a genetic distance of 1 from (A1 & A2)
I hope this is not too technical! Feel free to ask questions.
