Introduction to Autosomal DNA

What is it?

Autosomal DNA is the DNA which makes up autosomal chromosomes and are found in the nucleus of the cell. Most cells in our body (somatic cells) contain 23 pairs of chromosomes consisting of 22 pairs of Autosomal chromosomes and 1 pair of sex chromosomes (the X and Y chromosomes). One copy is of each pair inherited from our biological mother, and the other copy is from our biological father.

We are all unique

No two individuals who ever lived are the same – we are all unique. With the exception of identical twins, no two individuals have the same autosomal DNA profile. That’s why autosomal DNA testing is also known as “DNA Profiling” or “DNA Fingerprinting”.

What is Autosomal DNA Profiling?

Autosomal DNA Profiling (DNA Fingerprinting) usually refers to the testing of STR (short tandem repeat) markers found in Autosomal DNA. STRs are short fragments of DNA, usually 2 to 6 base pairs in length which are repeated over and over again in a defined location of the autosomal DNA. The length of the repeat can vary from person to person, and is inherited within the Autosomal chromosome.

Examining Autosomal STRs

During DNA fingerprinting, a panel of known STR locations (locus, plural loci) are tested to examine the number of repeat “alleles” at each locus. Since each individual has two copies of each autosomal chromosome, each locus will show two possible “alleles”.

An example is locus D5S818 which is found on chromosome #5. D5S818 is known to have repeats ranging from 7 to 17. After testing an individual, the results will show two values, ie. 9, 11. That means the individual inherited a 9 from one parent and an 11 from the other parent.

When a panel of different Autosomal STR markers are examined, the results are known as a “DNA Profile” or “DNA Fingerprint”.

The DNA Profile Test

When a DNA profile is ordered, select “hypervariable” regions of DNA are tested. These are regions of DNA that tend to be very different between different people. By assessing a few of these regions, it is already possible to have a unique DNA profile of a person. At SecuriGene, we test a total of 16 genetic markers.

Applications of Autosomal DNA STR Testing

The unique characteristics of Autosomal DNA STRs make it a powerful tool for many applications. Some of the most popular applications of Autosomal STR tests are as follows:

Family Relationship Testing
Paternity testing
To seek the biological father of a child, or to seek the biological child of a father.
Maternity testing
To seek the biological mother of a child, or to seek the biological child of a mother.
Full Sibling testing
To seek the full biological sibling(s) of an individual.
Half Sibling testing
To seek the half biological sibling(s) of an individual (same father only or same mother only).
Grandparentage testing
To seek the biological grandmother or grandfather of a child, or to seek the biological grandchild of a grandparent.
Aunt/Uncle testing
To seek the aunt or uncle of an individual on both the paternal and maternal lineage.
Nephew/Niece testing
To seek the nephew or niece of an individual on both the brother’s or sister’s lineage.
Identity Testing
Child Identification
To record your child’s DNA fingerprint as part of your child’s safety program. In the event that a child is missing, the DNA profile will assist law enforcement to find and positively identify the lost child.
Personal Identification
To record the personal DNA fingerprint of a family member for personal identification. The DNA profile is a personal identifier for an individual and the identification can be attached to the family tree and passed on to future generations. DNA fingerprinting can also be used to positively identify a family member during a disaster. Autosomal DNA testing was used for identification in a number of disasters, including 9/11, earthquakes, airline crashes and US military casualties.
Record and Preserve the Integrity of your Family Tree
To record and preserve the integrity of your family tree. Every individual is connected in the family tree through a defined relationship type. The DNA profile can be attached to the family tree and passed on to future generations as positive proof of relationship and to ensure the ongoing integrity of your family tree, even after death. Proof of family relationship generated through Autosomal STR testing is much stronger and more definitive than birth certificates and other forms of identification.
Matching and Identification
To match the DNA found on a licked envelope, hair sample, or other forensic sample to an individual, whether living or deceased.
