The Big Tree: R-Z38845
Z38845 is a G to A mutation at position hg19:7483249. This mutation is on the short arm of the Y chromosome in the IR1 region. There are 3 similar regions on the long arm of the Y chromosome and as such it does not show up cleanly in NGS tests if it shows up at all. NGS BAM files will usually show a mixture of G and A reads at this position. Paired end reads can pick up a difference between the regions and suggest that the mutation really is at hg19:7483249.

Mutations written with a red background fall within a region of the Y chromosome, such as the palindromic region, which has left the position of the mutation ambiguous. The true mutation may be at the indicated position, or at any one of a number of alternate positions.

Z18068
SNP names which are bold grey indicates that their exact position on the tree is uncertain. This SNP may belong further upstream or all downstream branches may not be positive for it. This is often the case for SNPs found in FGC kits or 1kG kits in regions not covered by BigY tests.
