mtDNA Analysis

RESULTS

The HVSI mitochondrial DNA (mtDNA) sequence of Mary Joe belongs to the Eurasian Halogroup N1a and match sequences from numerous Eurasian populations.

METHOD

We determined your Halogroup by sequencing a segment of several hundred base pairs of DNA found in the mitochondrial genome, referred to as the "Hypervariable Segment I" or HVSI (nucleotide positions 16024 through 16383). This segment was sequenced and systematically compared to a database consisting of HVSI sequences of individuals worldwide. The results of the comparison identify those sequences around the world that exactly or closely match your own. 

Your sequence was also compared to the Cambridge Reference Sequence of CRS. The CRS was the first human mitochondrial genome published in 1981. By comparing your sequence to the CRS, we can identify the name of the lineage to which you belong. These lineages are also called halogroups. Many halogroups are continent specific and subdivisions of these halogroups are often regionally specific.

Halogroup Assignment

The HVSI sequence for Mary Joe differed from the CRS at positions np (nucleotide position) 16147, np 16172 and np16223 examined within the first hypervariable region of the mitochondrial DNA (mtDNA). Ms. Poole's sequence carries a transversion at np 16147 from a cytosine (c) to a guanine (G). This sequence is consistent with the Eurasian halogroup N1a.
