This test is an indirect test based on statistical probabilities. Inconclusive results are possible.
Who can participate?
An avuncular DNA test (aunt/uncle test) allows for the assessment of a biological relationship between a child and the siblings of the presumed parent. Genetically, a child inherits 50% of their DNA from each of their biological parents, and a parent shares approximately 50% of their genetic heritage with their brother or sister. Consequently, a child typically shares around 25% of their DNA with their uncle or aunt.
The laboratory analyses the genetic matches between the child and the presumed uncle or aunt, subsequently calculating a statistical probability of avuncular relationship. To ensure the reliability of the DNA test, it is imperative that the uncle or aunt are biological siblings of the presumed parent.
Although they originate from the same parents, they are not genetically identical; hence, this test generally allows for an estimation of approximately half of the genetic profile of the parent whose relationship is to be verified.
The aunt
The aunt must be the full biological sister of the parent being investigated. For a maternity search between an aunt and her nieces or nephews, a mitochondrial DNA test is often recommended.
The uncle
The uncle must be the full biological brother of the parent being investigated. For a paternity search between an uncle and a boy, it may be relevant to use the Y-chromosome test.
Nephew / Niece
One or more children may participate in the test, whether they are boys or girls. The participating children can be full biological siblings or half-siblings.
The Involvement of a Parent in a Parentage Test
An avuncular DNA relationship test is based on the comparison of genetic profiles between a child and the biological siblings of the presumed parent. A child shares, on average, 25% of their DNA with an uncle or aunt, which enables the laboratory to statistically assess the existence of an indirect biological link when the parent cannot be tested.
When feasible, it is strongly recommended to include the DNA of the relevant biological parent (mother or father) in the test. This additional participation assists the laboratory in better isolating the genetic contribution from the parent, thereby refining the analysis of the relationship with the uncle or aunt.
Result: more reliable and precise conclusions.
Generally, the greater the number of genetic profiles analysed, the more conclusive the avuncular DNA test results will be.
